We demonstrated that ectopic overexpression of GhFT1 in tobacco, other than promoting flowering, promoted lateral shoot outgrowth at the base, induced more axillary bud at the axillae of rosette leaves, altered leaf morphology, increased chlorophyll content, had higher rate of photosynthesis and caused flowers abscission. Analysis of gene expression suggested that flower identity genes were significantly upregulated in transgenic plants. Further analysis of tobacco FT paralogs indicated that NtFT4 , acting as flower inducer, was upregulated, whereas NtFT2 and NtFT3 as flower inhibitors were upregulated in transgenic plants under long-day conditions, but downregulated under short-day conditions. Our data suggests that sufficient level of transgenic cotton FT might disturb the balance of the endogenous tobacco FT paralogs of inducers and repressors and resulted in altered phenotype in transgenic tobacco, emphasizing the expanding roles of FT in regulating shoot architecture by advancing determine growth. Manipulating the ratio for indeterminate and determinate growth factors throughout FT -like and TFL1 -like gene activity holds promise to improve plant architecture and enhance crop yield. Plants sense multiple environmental cues and endogenous signals to determine the appropriate timing of flowering, which is an orchestrated process through the integration of multiple environmental cues and endogenous signals. Genetic and molecular analyses of flowering-time mutants in Arabidopsis have established the current model, in which five major pathways mainly control the transition from the vegetative to reproductive phase. FT -like and TFL1 -like genes modulate flowering transition and inflorescence architecture Kobayashi et al. FT promotes the transition to reproductive development and flowering, whereas TFL1 represses this transition. Numerous studies have concluded, FT orthologs possessing floral inductive function in woody perennials Hisada et al. Previously study suggests a conserved ancestral function of FT -like proteins in transmitting inductive signals in plants. However, recent studies showed that FT -like genes in numerous species play important roles in various physiological aspects other than flowering Pin and Nilsson, FT and TSF modulate lateral shoot outgrowth in Arabidopsis , and link the floral transition and lateral shoot development to maximize the reproductive success of a plant Hiraoka et al. FT has also been demonstrated to be involved in multiple steps of axillary bud development, likely to coordinate axillary shoot development with flowering Niwa et al. Ectopic overexpression of FT in cotton through virus-induced flowering uncouples flowering from photoperiodic regulation and promotes determinate growth habit in all aerial organs McGarry and Ayre, Florigen is thus established as a plant protein functioning as a general growth hormone. Also, allelic variation at the SFT locus is implicated in heterosis of yield Krieger et al. Some members of FT -like gene family modulate growth of underground storage organs. The Gossypium Cotton is one of the most important cash crops worldwide, having a large impact on our economy and everyday life. Gossypium species are naturally a photoperiodic that does not flower until the shorter days of late summer or fall. Domestication of the two allotetraploid that comprise the majority of world-wide cultivations, Gossypium hirsutum and G. Cotton originated from a tropical region, and its growth is very sensitive to low temperature and soil conditions in temperate cultivation regions. Flowering earliness is an important objective in most cotton breeding programs. However, the molecular mechanisms regulating the transition from vegetative to reproductive growth in cotton are less well characterized than in other plant species, mostly due to the complexity of cotton genome and scarcity of cotton flowering time mutants. In this study, we further dissected its roles by ectopic expression of GhFT1 in wild-type WT tobacco. As expected, GhFT1 obviously promotes the floral transition in transgenic tobacco plants by producing terminal flower. However, boosting flowering is just one of the pleiotropic functions of GhFT1. In addition to precocious flowering, we observed that tobacco plants carrying 35S::GhFT1 had more lateral shoots outgrowth at the base, axillary buds at rosette axil, altering leaves morphology and causing flower abscission. Our data suggests that sufficient level of transgenic cotton FT homolog might disturb the balance of endogenous FT -like proteins and disorder the ratio of inducer and repressors, resulting in inflorescence and plant architecture change. The seeds of N. NC89 and N. The aseptic seedlings of N. The N. The 5. Tobacco plants N. NC89 plants stably by A. The transient expression assays in tobacco were performed according to the method described by Voinnet et al. The A. The agrobacteria cells were left to standing for 3 h at room temperature and then infiltrated into the abaxial side of leaves of 4-weeks-old N. Primers information used in this research are listed in Supplementary Table S5. U , which was used as an internal control. At least three replicate assays were performed with independently isolated RNA for all experiments. PCR products were subsequently separated on a 1. Determination of chlorophyll content in transgenic plants grown under LD and SD conditions were estimated according to the method described by Xu et al. The homogenate was centrifuged at 10, rpm for 10 min. Leaf area was measured using paper-cutting method described by Hattersley with some modification. We digitally photographed leaves of different transgenic tobacco lines and WT plants. Photos of different lines were printed randomly with A4 paper No. Then the printed photos were cut off carefully. Weight of leaves W1 and their corresponding cut-off papers W2 were weighed. At least three replicate assays were performed independently in this experiment. Light curve data were analyzed using the built-in program in LI system. We next to observed the green fluorescence using CLSM. To exclude the possibility of cell wall association of GhFT1-GFP, we performed the plasmolysis assay by sucrose treatment. However, we were not able to observe an ideal picture of plasmolysis due to the very thick cell wall of tobacco root tips. Green fluorescence was detected in the peripheral cytoplasm surrounding the vacuole as well as in the nucleus, which was similar to the cells expressing GFP alone Figure 1. As our previous report Guo et al. Micrographs showing cells expressing GFP control, upper lane or GhFT1-GFP bottom lane fusion protein, which were examined under fluorescent-field illumination left to examine GFP fluorescence, and under bright-field illumination middle , and by confocal microscopy right for an overlay of bright and fluorescent illumination. Arrow, plasma membrane; triangle, nucleus. As shown in Supplementary Figure S3B, GhFT1 was expressed in all the selected transgenic lines, and the flowering time was positively correlated with expression level of GhFT1 in transgenic lines. To explore the potential of GhFT1 in the regulation of flowering in tobacco, this gene was overexpressed in N. We obtained numerous transgenic lines from two times of independent transform assays, and all of them were confirmed by PCR data was not provided. The majority of 35S::GhFT1 primary transformants flowered much early than the WT, both in terms of time and the number of leaves before flowering Supplementary Table S2. In the homozygous T3 plants, 14 showed significantly early flowering phenotype under LD line 1 and line 2 are shown as an example in Figure 2A , and 12 also showed precocious flowering compared with the WT plants under SD conditions line 15 and line 16 are shown as an example in Figure 2B. In addition, transgenic lines had rapidly elongated internodes and reduced internodal length, and thereby developed dwarf stature when flowering than the controls under both conditions. Phenotype analysis of transgenic tobacco Nicotiana tabacum lines that ectopically expressed GhFT1. E Appearance of 53 days WT tobacco and 5. Scale bars: 3. Previously, it has been shown that a transgene consisting of 5. To further analyze the function of GhFT1 in promoting flowers, we designed the 5. The average flowering time for these 5. These data combined with previous report by Guo et al. Nicotiana tabacum is an annually grown herbaceous plant with little branches. Many flowered inflorescences arise at the terminal after floral transition of the plant Amaya et al. Axillary buds are formed at the axillae of foliage leaves, and will further develop into an inflorescence shoot Figure 3A. Surprisingly, we also observed that the 35S::GhFT1 transgenic plants produced more axillary buds after floral transition under LD conditions, but these axillary buds could not further develop into lateral shoots Figures 3B,D , whereas the WT tobacco plants could. Conversely, more lateral shoots were generated at the base of transgenic plants, which do not usually appear in the WT plants of laboratory accession, N. They also could not develop into lateral shoots finally, and more lateral shoots were generated from stem base at early buds stage Figures 3F,G ; Supplementary Figure S4C. These observations suggested that ectopic expression of GhFT1 in tobacco could modulate lateral shoot outgrowth and axillary bud set in additional to floral transition. Ectopical overexpression of GhFT1 promotes lateral shoot outgrowth in tobacco. A The non-transformed WT tobacco plant develops lateral shoots white arrow at the axillary buds after flowering. Scale bars: 2 cm. Surprisingly, we also noted that change of leaf morphology appeared in all the 35S::GhFT1 transgenic plants. We compared leaves morphology from apical to basal position among the transgenic lines and the WT tobacco siblings. The leave area in the transgenic lines was significantly smaller than in the WT plants. Under LD conditions, the leaves in line 5 appeared to be much longer and narrower than that in the WT plants, but leaves in line 6 appeared to be much shorter and wider Figure 4A. We then measured chlorophyll content, suggesting both line 5 and line 6 had higher total chlorophyll content than the WT plants Figure 4C. Leaf mass per area LMA is a key trait in plant growth and an important indicator of plant strategies, which is most closely correlated with a relative growth rate, and has been used wildly in plant ecology, agronomy, and forestry Poorter et al. Overexpression of GhFT1 in tobacco has a powerful influence on leaf development. A Comparison of apical left , medial middle two , and basal bottom leaves among WT plant and the 35S::GhFT1 transgenic line 5 and line 6 at 7 weeks under LD conditions. Scale bar: 1 cm. We next set out to explore whether the change of leaf morphology and increasing of chlorophyll content in transgenic plants could enhance photosynthesis. The efficiency of photosynthesis was determined by LI portable photosynthesis system in different light intensity. As shown in Figure 5 , the transgenic tobacco lines showed higher photosynthetic efficiency than the WT plant in LD as well as SD conditions. This suggests, GhFT1 might play important roles in the modulation of leaf development in cotton by increasing photosynthesis and chlorophyll content other than floral transition. Overexpression of cotton GhFT1 increased photosynthetic efficiency in tobacco. The WT plant and transgenic plants were 7 weeks-old after transfer to the phytotron. Nicotiana tabacum cv. NC89 is a typical cymose inflorescence in which the first-formed flower develops from the growing region at the top of the flower stalk, and the development of the flower at the apex is followed by two new flower axes developing from buds opposite on another Amaya et al. For example, in the 35S:GhFT1 line 18, after the first flower opened, it abscised form the stalk Figure 6B under SD conditions, so it produced very few flowers and few mature seeds. In transgenic line 17, it could not present the regular flowers, due to their abscission before opening Figure 6C. One of the reasons may be their flowers failed to enter meiosis, and eventually the plants did not produce any seed capsules. No cymose inflorescences similar to the WT plants Figure 6A were formed in all these transgenic lines. Similar to SD conditions, we also observed that these transgenic lines showed buds abscission at the initiation of early bud set under LD conditions Figures 6D,E. However, the extent of floral bud abscission was alleviated, and flowers could normally open and seed set at later developmental stage Figures 2A,C. Flower abscission behavior of transgenic tobacco lines that overexpressing GhFT1 with severe phenotype. A The cymose inflorescence in the WT flowers with no flowers abscission at flower opening. Arrow indicated the abscised flower. Scale bars: 1 cm. Viewed form outside, the transgenic plants showed normal flower development, produced fertile flowers and normal seeds Supplementary Figures S6A,E. For example, line 5 and line 6 showed a smaller flower than the WT control, but no difference of phenotype in stamen, stigma, petal, ovary, and sepal were observed Supplementary Figures S6B—D , suggesting that the product of GhFT1 had no influence on the development of flower organs. In the present model, FT protein, is now widely established as a major component of florigen, a systemic signal that induces flowering in responsible to daylength, which is translocated through the phloem to the SAM Corbesier et al. The MADS-domain transcription factor AP1 is a key regulator of Arabidopsis flower development, controlling the onset of flower development Wigge et al. SOC1 integrates multiple flowering signals including photoperiod, temperature, hormone, and age-related signals, involving in the process of floral organ formation, meristem determinacy, and prevention of secondary growth and shoot longevity Lee and Lee, ; Hiraoka et al. LFY , which encodes a plant specific transcription factor, plays dual roles in determining floral meristem identity and floral organ patterning via AP1 and other floral homeotic genes Moyroud et al. We next detected the expression profiles of the tobacco flower meristem identity genes among the transgenic and the WT siblings by qRT-PCR. NtAP1 , JQ Four FT -like genes have been identified in N. To explore whether the early flowering phenotype was correlated with the endogenous NtFTs expression in 35S::GhFT1 transgenic lines, we next further detected the expressions profile of the four FT paralogs. We were unable to detect NtFT1 expression under both conditions, while Harig et al. A wide spectrum of research of FT orthologs from angiosperms has been demonstrated their conserved function in the regulation of flowering time Pin and Nilsson, However, the developmental mechanisms targeted by FT orthologs to transform vegetative meristems into reproductive organs remain unclear. To investigate the developmental mechanism targeted by GhFT1 protein, we further unveiled its overall growth effects by overexpressing GhFT1 in tobacco. Furthermore, the 5. The precocious flowering phenotype regardless of photoperiod indicated its conserved roles in floral induction. Although FT orthologs have been identified and characterized from numerous plant species, the subcellular distributions of many of them have not been clearly studied. FT-GFP fusion protein in transgenic plant has been detected to move through the phloem from the leaves as the place of light perception to the shoot apex as the position of flower formation only in limited plant species Supplementary Table S3. However, the size of the fusion protein restricted the long-range function of FT. Previously publication have shown that overexpression of FT orthologs in tobacco could accelerate flowering in different plant species Supplementary Table S4 , including tomato Shalit et al. Therefore, GhFT1 might have upregulated them to regulate flowering in transgenic tobacco plants. Tobacco is a determinate species in which main shoot terminates by converting into a flower, with subsequent growth occurring only from lower meristems Figure 3A. A number of axillary meristems generated below the apex also develop into terminal flowers in a cymose pattern Amaya et al. Although florigen was originally proposed as a flowering hormone, it is now apparent that FT is a universal growth factor affecting several aspects of plant architecture. In addition to promoting flowering, we observed that the transgenic tobacco plants showed pleiotropic phenotype different from the WT control, suggesting that GhFT1 played multifaceted roles during plant development. That Arabidopsis FT is involved in the promotion of lateral shoot outgrowth and axillary bud initiation were previously proposed Hiraoka et al. It has been previously reported that elevation of FT concentration promotes more determinate habit, and influences leaf development Shalit et al. Here, we also observed that leaf morphology of the 35S::GhFT1 transgenic tobacco lines was very different from that of WT. Firstly, the leaves of transgenic lines appeared much more dark green and fleshy compared with WT plants. Accordingly, the chlorophyll content in transgenic lines was higher than that in the control plants Figure 4C ; Supplementary Figure S5C. Secondly, compared with other WT plants, leaves were shorter and wider in some transgenic lines, whereas leaves were longer and narrower in other transgenic lines. Likewise, transgenic lines showed higher photosynthetic efficiency than the WT plants Figure 5. We surmised that GhFT1 could link the transition to floral with leaf development. The leaf morphological change in the 35S::GhFT1 transgenic tobacco lines is reminiscent of resent reports on overexpression FT orthologs in different plant species. When Arabidopsis FT is ectopically overexpressed in ancestral cotton accession TX through virus-induced flowering, it also generated the lanceolate leaf shape McGarry and Ayre, Endo et al. Xiang et al. Overexpression of tobacco NFL1 in tobacco results in dwarf stature, reduced internode length, and thickened leather-like leaves Ahearn et al. Furthermore, Flachowsky et al. The high expression of NFL1 Figure 7 in tobacco driven by the overexpression of GhFT1 might contribute to the leaf shape and plant architecture. Ectopically overexpressed transgenic plants containing FT orthologous genes exhibited similar phenotype in leaf shape and plant architecture, suggesting that the function of FT -like gene family is highly conserved during evolution. Surprisingly, we also observed obvious premature flowering abscission in early developmental stages in the extremely early flowering transgenic lines carrying 35S::GhFT1 , resulting in fewer mature seeds Figure 6. In tomato, SFT was also reported to accelerate mature and promote abscission zone formation Shalit et al. Overexpression of Arabidopsis FT in the ancestral cotton accession TX delivered by virus-induced flowering caused many of flowers abscission before producing mature bolls McGarry and Ayre, The abscission trait is considered as an innovation in angiosperms, and is regulated by multifactor, including auxin, ethylene, and jasmonic acid even day length Shalit et al. Further study would clarify the possible mechanism for the precocious floral organ abscission in tobacco plants overexpressing cotton GhFT1. It is now apparent that the relative ratios of FT to other members of the PEBP gene family have influenced the balance of indeterminate and determinate growth in many plant species, and play important role in the floral transition and architecture formation. The recent report showed N. However, the exact mechanism in the control of floral transition remains very unclear. As expected, NtFT4 showed significantly upregulated expression in all the transgenic tobacco plants under both light conditions Figures 8A,B. The balance model predicts that FT and TFL1 concentration fluctuate, and balance are re-fined in local tissues to give rise to different architecture McGarry and Ayre, The expression levels of GhFT1 in LD condition tobaccos were much higher than that in SD condition Figure 2 , suggesting that in LD and SD conditions, tobacco might have different concentration of florigen for mediating floral transition. High expression of cotton GhFT1 completely influenced the expression level of endogenous FT genes in tobacco. The problem balance will further influence the expression levels of flowering meristem identity genes, such as NAP1 , NFL1 , and NtSOC1 Figure 7 , resulting in developing multifaceted phenotypes: early flowering, axillary buds set, lateral shoot outgrowth, leaf development change and flower abscission. However, further extensive research is needed to clarify these scenarios. Taken together, overexpression of cotton GhFT1 in tobacco promotes precocious flowering uncouple from photoperiod, showing that FT paralog evolves a conserved function of floral promoter in fiber plants. Introducing of transgenic cotton FT disturbs the balance of endogenous FT paralogs including inducers and repressors, and further disturbs other PEBP family members balance through antagonistic functions. We here present evidences that sufficient levels of FT activity might modulate axillary and lateral shoot outgrowth, influence leaf development and promote flower abscission, supporting the view that florigen functions as general growth hormone mediating growth and termination. These finding further extends the knowledge for plant florigen. Judicious manipulation of the ratio for indeterminate and determinate growth factors, mediated by a balance of FT -like and TFL1 -like gene activities by transgenic technology, holds promise for improved plant architecture optimized for region-specific environment and enhanced crop yield in order to meet the agricultural demand of the rapidly expanding global population.
