“Decode” litchi genome
Propose the origin and domestication falsehoodKomiks said that in this study, scientific scientists used the latest genome sequencing data such as second-generation Illunina to optimize the genomeThe assembly strategy is to complete the assembly of the pseudochromosome level of the litchi genome and the structural annotation of the genome-encoded gene. The Cinema project team proposed the hypothesis of “one center of origin, two independent domestication events” of lychee, providing genomic evidence for YunCinema is 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. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the results press 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 mechanism of forming important economic traits of litchi, but also develop corresponding breeding and cultivation control technologies, but also provide important references for promoting related research on other plants of the family of no family, such as longan.” Liu Yahong, president of Huanong, said that the high-level paper published by the school’s team in Nature-Genetics marks a new height for the school’s litchi research. href=”https://comicmov.com/”>Cinema indicates that lychee scientific research has entered the post-genomic era.
CinemaBabaylan Revealing the mechanism for flowering regulation
Improving the benefits of lychee planting
The market launch of lychee fresh 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 ripe varieties in lychee, and in addition, the two and Guangxi are medium-ripe production areas at the middle latitude of Babaylan. 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, Komiks‘s paper is fromThe genomic level has systematically studied the regulatory mechanism of lychee blossom, and found that the DNA sequence deletion of a specific section of Cinema in lychee may be an important factor in the formation of lychee in different flowering stages. This is very important for extending the yield period of litchi from 2 months to 4 months or even longer, reducing seasonal sales pressure on fresh fruits and improving the benefits of litchi planting. “This research is of milestone significance for promoting the basic research and breeding application of lycheeKomiks and even several important fruit tree crops in the Wuwan 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 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 preliminary goal of leapfrog improvement of the basic biological research level of lychee.
