Why do trees need a genetic passport

In the future, each forest will have its own genetic passport. Why you need it, and why you need to spend millions of dollars on it, we tell in the material RBC Trends

How to decode the genome of trees Imagine that a stack of identical logs is passed through a shredder, the pieces are mixed and then restored to the original texts. Figuratively — this is the technology of sequencing (decoding) of nucleotide sequences of DNA — the material of heredity. DNA is isolated from a test sample (e.g., leaves, needles, bark, or tree saw). Then it is cut randomly into small fragments, each of which needs to be 'read'. After that, short reads (reads) of 100–300 nucleotides are collected into successive logical chains corresponding to chromosomes of the genome. This is what bioinformatics does. Trees have much longer genomes than humans. Unlike animals or humans, whose genome was “purified” of unnecessary information and unnecessary DNA in the course of evolution, this process was significantly slowed down in trees. For example, coniferous species have gigantic DNA chains. The spruce or pine genome is larger than the human genome in 6–9 ra...
