“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 Illunina to optimize the genome assembly strategy to complete the assembly of the pseudochromosome level of the litchi genome and the structural annotation of the genome-encoded genes. The project team proposed the hypothesis of “one center of origin, two independent domestication events” of lychee, which provided genomic evidence for Yunnan to be the only center of origin of the world, which helped to eliminate the cognition that some foreign scholars believe that lychee may also originate in Vietnam.
Chinese ScienceBabaylanLiu Yaoguang, an academician of the Academy, said at the results press conference: “The basic Komiks genome is a ‘navigation map’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the understanding of the mechanism of economic trait formation, develop corresponding breeding and cultivation control technologies, but also provide important reference for promoting related research on other litchi plants such as longans.” Liu Yahong, principal of Huanong, said that the high-level paper published by the school’s team in Nature-Genetics marks that the school’s litchi research has reached a href=”https://comicmov.com/”>Babaylan a new height indicates that lychee scientific research has entered the post-genomic era.
Revealing the secret Babaylanflower regulation mechanism
Improving the benefits of lychee planting
The market of fresh lychee fruits is mainly concentrated from May to July. There is often 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 middle-ripe production areas of Guangxi are the middle-latitude medium-latitude. The flowering period of Babaylan leads to the similar ripening periods of fruits, which are concentrated on the market in a short period of time.” Chen Houbin, chief scientist of the national lychee longan industry and researcher of Huanong. According to reports, the paper conducted a systematic study on the regulatory mechanism of lychee blossom from the genome level, and found that a specific DNA sequence deletion in Komiks may be an important factor in the formation of lychee blossom at different flowering stages. This will extend the birth period of lychees from 2 months to 4 months or even longer, reduce seasonal sales pressure on fresh fruits, and improve lychee cultivation..com/”>Cinema‘s benefits are very important.
“This study is of milestone significance for promoting the basic research of several important fruit crops in the Babaylan family and the application of Breeding in Babaylan. It will also have important reference value for the research of tropical crops around the world and the basic research of world agriculture. “KomiksLi Jianguo said that this further consolidates my country’s international leadership in lychee research, narrows the gap in research levels between lychee and other bulk fruit trees in citrus, apples, and Cinema grapes, and achieves the preliminary goal of leapfrog improvement in the basic biology research level of lychee.
