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 lyCinema Huanong Subtropical Agricultural Bioresources Protection and Utilization” was jointly completed with the Guangdong Agricultural Sciences Komiks Institute, the Chinese Academy of Tropical Agricultural Sciences and other domestic and foreign units, “Two diverse haplotypes from a highly heterozygous lyCinemachee genome suggesteKomiksst independent domestication eCinemavents for early and late-maturing cultureCinemavars” (two different haplotypes in the litchi genome indicate that the early and late-maturing cultivars are domesticated independently) were published in Nature Genetics. Corresponding authors include Researcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbin. The first authors are Professor Hu Guibing of Huanong, PhD student Feng Yunting, Professor Liu Chengming, Professor Wu Zhenxian, etc.
“Decoding” the litchi gene, Komiks group, proposed the origin and domestication hypothesis of Cinema
In this study, scientists Cinema using the latest genome sequencing data such as the second generation Illunina, to optimize the genome assembly strategy, complete the assembly and genome encoding base of the “Fai Zixiao” litchi genome pseudochromosome level and genome encoding base. href=”https://comicmov.com/”>Komiks structure comments.
Project GroupKomiks proposed the hypothesis of “one center of origin, two independent domestication events”, which provided genomic evidence for Yunnan to be the only center of origin of lychees in the world, and helped to eliminate the cognition that some foreign scholars believe that Babaylan lychees may also originate from Vietnam.
Academician of the Chinese Academy of Sciences Liu BabaylanYoguang said at the results press conference: “Genome is a ‘navigation map’ for the formation of plant traits.KomiksDecoding 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 regulatory 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 school team published in Nature-Genetics. href=”https://comicmov.com/”>Babaylan‘s high-level paper marks a new high in the school’s lychee research. Cinema indicates that lychee research has entered the post-genomic era in full.
Revealing the flowering regulation mechanism
Improving the benefits of lychee planting
Fresh lychee fruits are mainly concentrated in May to July. Seasonal surplus of fruits often occur in production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychees, and the middle-ripe production areas of Guangxi are concentrated in the flowering period, resulting in the similar ripening periods of fruits, and they are concentrated in a short period of time. ” said Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and a researcher of Huanong. According to reports, the paper conducted a systematic study on the litchi flowering regulation mechanism from the genome level and found that litchiKomiks‘s DNA sequence deletion may be an important factor in the formation of lychees in different flowering periods. This is very important for extending the lychee production period from 2 months to 4 months or even longer, reducing the sales pressure of fresh fruits in seasonal sales, and improving the benefits of lychee planting. “This study is of milestone significance for promoting the basic research and breeding application of several important fruit crops of lychee and even the Non-Artaceae family. It will also provide a basic research on tropical crops around the world and basic research on world agriculture. href=”https://comicmov.com/”>Babaylan has important reference value. “Li Jianguo said that this Komiks 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 level of basic biology research in lychee.
