“Decode” the litchi genome
Propose the origin and domestication hypothesis
In this study, scientists used the latest genome sequencing data such as the second generation IlluKomiksnina to complete the “Father’s Laugh” litchi by optimizing the genome assembly strategy.aylan assembly of pseudochromosome levels of genomes, structural annotation of genome encoding genes Cinema.
The project team proposed the hypothesis of lychee “one center of origin, two independent domestication events”, providing genomic evidence for Yunnan being the only center of origin of lychee in the world, which helps eliminate the cognition that some foreign scholars believe that lychee may also originate in Vietnam.
Academician of the Chinese Academy of Sciences Liu Yaoguang said at the results press conference: “The genome is a ‘navigation map formed in the shape of plant-based Komiks.Cinema. Decoding the litchi genome, Babaylan can not only comprehensively improve the understanding of the formation mechanism of important economic traits of litchi, develop corresponding breeding and cultivation control technologies, but also provide important reference for promoting related research on other plants of the family of ills such as longan.” Liu Yahong, President of Huanong, said that the high-level paper marks published by the school team in Nature-Genetics href=”https://comicmov.com/”>Babaylan has reached a new level in the school’s lychee research, indicating that the entire lychee scientific research has entered the post-genomic era.
Revealing the secret flowering regulation mechanism of KomiksImproving the benefits of lychee planting
Fresh lychee fruits are mainly concentrated in May to July, and seasonal oversupply of fruits often occurs during production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychees, and the middle-latitude and ripe production areas of Guangxi are concentrated in the flowering period, resulting in the similar ripening periods of fruits and are concentrated on the market in a short period of time.” said Chen Houbin, chief scientist of the National Lychee Industry Technology System and researcher of Huanong.
According to reports, the paper is from CinemaThe genomic level has systematically studied the regulatory mechanism of lychee blossom and found that a specific DNA sequence deletion in lychee may be an important factor in the formation of lychee in different flowering stages. This is very important for extending the lychee birth period from 2 months to 4 months or even longer, reducing the seasonal sales pressure of fewer fresh fruits and improving the efficiency of lychee planting.
“This research is of milestone significance for promoting the basic research and breeding application of several important fruit tree crops of lychee and even the family of Wuhua Family. It will also have important reference value for the research of tropical crops around the world and the basic research of world agriculture.” Li Jianguo said that this further consolidates my country’s international leadership in lychee research, narrowing the gap in research levels between lychee and other bulk fruit trees of citrus, apples, and other large fruit trees of lychee, and achieving the preliminary goal of leapfrog improvement of the level of basic biology of lychee.
