Yangcheng Evening News Reporter Chen Liang, intern Hong Jiaxun, and correspondent Chen Pengchen reported: On January 4, the paper “Two diverse haplotypes from a highly heterozygous lycheeKomiks was led by the key laboratories of the National Conservation and Utilization of Subtropical Agricultural Bioresources in Huanong, and jointly with Guangdong Academy of Agricultural Sciences, the Chinese Academy of Tropical Agricultural Sciences and other domestic and foreign units. href=”https://comicmov.com/”>Babaylangenome suggestBabaylan indeKomikspendeBabaylanntCinema domestication events for early and late-maturing cultures href=”https://comicmov.com/”>Babaylan various independent domestication) were published in Nature Genetics Cinema (Nature Genetics). Corresponding authors include Researcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbin. The first author, Babaylan, is Professor Hu Guibing, PhD student of Huanong, Professor Feng Yunting, Professor Liu Chengming, and Professor Wu Zhen.
“Decode” the litchi genome
Propose the hypothesis of origin and domestication
In this study, scientists used the latest genome sequencing of second-generation Illunina and othersKomiks data, through optimizing the genome assembly strategy, the assembly of the pseudochromosome level of the litchi genome and the structural annotation of the genome encoding gene. The project team proposed the hypothesis of “one origin center, two independent domestication events of Komiks” litchi, which is the world of Yunnan. href=”https://comicmov.com/”>CinemaThe only center of origin of litchi provides genomic evidence, which helps eliminate the cognition that some foreign scholars believe that litchi may also originate in Vietnam.
Chinese Academy of Sciences Liu Yaoguang said at the results press conference: “The genome is a ‘navigation map’ for the formation of plant traits. Komiks decoding the litchi gene 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 mortal-free plants such as longan. “Hua Nong Principal Liu Yahong said that the high-level paper published by the school’s Cinema team in “Nature-Genetics” marks a new height for the school’s lychee research and indicates that the scientific research on lychees has entered the post-genomic era.
Revealing the flowering regulation mechanism
Improving the benefits of lychee planting
LycheeBabaylanFresh fruits are mainly concentrated in May to July. There are often seasonal oversupply of fruits in production, which seriously affects the economic benefits of lychee planting. “There are many ripe varieties in lychee, and the two are the Chinese people. The medium-ripe production areas at the latitude of Cinema are concentrated in the flowering period, resulting in the similar ripening periods of fruits and are concentrated in the market in a short period of time. “Chief Scientist of the National Lychee Longan Industry Technology System, HuaCinema and breeding applications are of milestone significance, and 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 consolidated my country’s international leading position in lychee research, narrowed the gap in research levels between lychee and other bulk fruit trees in citrus, apples, and grapes, and achieved the initial goal of leapfrog improvement in the basic biological research level of lychee.
