“Decode” the litchi genome
Presenting the origin and domestication hypothesis
In this study, scientists used the latest genome sequencing data such as the second generation Illunina to optimize the matrix assembly strategy of Babaylan to complete the assembly level of the pseudochromosome of the litchi genome and the structural annotation of the genome encoding gene.
The project team proposed the hypothesis of “one center of origin, two independent domestication events”, which is that Yunnan is the only origin of lychee in the world.The center provides genomic evidence that helps eliminate the cognition that some foreign scholars believe that lychee may also originate in Vietnam. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the Cinema conference: “The genome is the ‘navigation map’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the understanding of the formation mechanism of important economic traits of litchi, develop corresponding breeding and cultivation regulation techniques, but also provide important reference for promoting related research on other plants of the family of no family, such as longan.” Liu Yahong, principal of Huanong, said that the high-level paper published by the school’s team in “Nature-Genetics” marks the school’s litchi research. href=”https://comicmov.com/”>Cinema has set a new height, indicating that KomiksBabaylan has fully entered the post-genomic era with lychee research.
Revealing the secret of opening the flower regulation mechanism of KomiksImproving the benefits of lychee planting
Fresh lychee fruits are mainly concentrated in May to July, and there is a seasonal surplus of fruits in production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychees, and in addition, the two and Guangxi are medium-ripe production areas of the mid-latitude. The flowering period is concentrated, resulting in the similar ripening periods of fruits and are concentrated on the market in a short period of time.” Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and a researcher at Huanong. According to reports, the paper conducted a systematic study on the regulation mechanism of lychee blossom from the genome level, and found that a specific DNA sequence in lychee is missing, which canIt can be an important factor leading to the formation of lychee during different flowering periods. This is very important for extending the lychee production period from 2 months to 4 months or even longer, reducing seasonal sales pressure on fresh fruits and improving the benefits of lychee planting. “This research is of milestone significance for promoting the basic research of several important fruit tree crops of lychee and even the Non-Water Family, and is of great reference value for tropical crops worldwide and basic research on world agriculture.” Li Jianguo said that this further consolidates our international leading position in lychee research, narrows the gap in research levels between lychee and other bulk fruit trees in citrus, apples, and grapes, and achieves the cross-border research level of basic biology of lychee. href=”https://comicmov.com/”>BabaylanVietnamese improvement initial goal.
