monkey head mushrooms
genetic research has made important progress. Based on the single
nucleotide
polymorphism in the whole
gene
group, the scientists indicated the monkey head mushroom recombination exchange
event
, which is the first time that quantitative genetics has been used in large
fills
to analyze the genetic mechanism of recombinant variation, and the results are conducive to deepening the understanding of large fungal subtracting spl uprooting and combination. The findings have been published online.
according to Yu Wenbing Associate Researcher, monkey head mushroom as an important large fungus, with high edible and medicinal value, has "shanzhen monkey head, sea odor bird's nest" said. Based on the genome-wide polymorphism of single nucleotides, the scientists indicated the recombinant exchange event of monkey head mushrooms, identified 59 recombinant exchange hot spots and their rich base sequence, and excavated the genetic site of regulating recombinant variation. Isogen recombination is a key link in de-degeneration division, which provides a large number of genetic variations for sexual reproductive organisms and is the basis of genetic diversity and species evolutionary adaptability. The obtained monkey head mushroom genome, single nucleotide polymorphism marker in the whole genome, high-precision genetic map is an extremely valuable big data resource, which lays the foundation for the study of monkey head mushroom biology and genetic improvement. Combined with second- and third-generation sequencing techniques, the scientists completed the high-quality genome assembly of monkey-headed mushrooms in advance, and constructed the first microsatellial marking database of monkey-headed mushrooms. Using genome resequencing, the first high-precision chain map of monkey-headed mushrooms is constructed, and it is also the highest density genetic map of edible bacteria.
research has been supported by projects such as the Science and Technology Innovation Project of the Chinese Academy of Agricultural Sciences, the National Natural Science Foundation of China and the Natural Science Foundation of Hunan Province. (Communicator Liao Yongfeng)
