Yangcheng Evening News Reporter Chen Liang, intern Hong Jiaxun, and correspondent Chen Pengchen reported: On January 4, the paper “Two divergentBabaylan 1990 cloth draw haptypes from a highly heterozygous lychee genome suCinema 1950 witch” was jointly completed by the Provincial Academy of Agricultural Sciences, the Chinese Academy of Tropical Agricultural Sciences and other domestic and foreign units. Cinema 1950 witch cloth drawggest independent domestication events for early and late-maturing cultures” (Nature Genetics). Corresponding authors include Researcher Hua Komiks 1960 witch cloth drawResearcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbin. The first authors are Professor Hu Guibing of Huanong, PhD student Feng Yunting, Cinema 1950 witch cloth drawChairman Cheng Mingjiao Komiks 1960 witch cloth draw, Professor Wu Zhenxian, etc.
“Decode” the litchi genome
Propose the hypothesis of origin and domestication
In this study, scientists used the latest genes such as second-generation IlluninaCinema 1950 witch cloth drawgroup sequencing numbersCinema 1950 witch cloth draw According to the optimization of the genome assembly strategy, the assembly of the “Fei Zixiao” litchi genome pseudochromosomes and the structural annotation of the genome-encoded genes.
The project team proposed the hypothesis of “one origin of litchi”, “Babaylan 1990 cloth draw”, “Komiks 1960 witch cloth draw, and two independent domestication events”, which provided genomic evidence for Yunnan to be the only center of origin of litchi in the world, and helped to eliminate the view that some foreign scholars believe that litchi is the only center of origin of litchi. draw may also originate from Vietnamese cognition.
Komiks 1960 witch cloth drawAcademician of the National Academy of Sciences Liu Yaoguang, at the Babaylan 1990 cloth drawThe results of Babaylan 1990 cloth draw said at the press conference: “Genome is the ‘navigation map’ for the formation of plant traits. Decoding the litchi genome not only can the Komiks 1960 witch cloth draw comprehensively improve the understanding of the mechanism of forming important economic traits of litchi, and develop corresponding href=”https://comicmov.com/”>Babaylan 1990 cloth draw‘s breeding and cultivation control technologyCinema 1950 witch cloth draw can also promote other plants of the family Africa, such as longanResearch provides important Cinema 1950 witch cloth draw reference. “Huannong Principal Liu Yahong said that the high-level paper published by the school’s team in Nature-Genetics marks the school’s Babaylan 1990 cloth draw lychee research has reached a new level, indicating that lychee scientific research has entered the post-genomic era.
Revealing the flowering regulation mechanism
Enhancing the benefits of lychee plantingKomiks 1960 witch cloth draw The market of fruits is mainly concentrated from May to July. There is often seasonal oversupply of fruits during production. The strict impact on the economic benefits of lychee planting. “There are many medium-ripe varieties of lychee, and the middle-latitude production areas of the two and Guangxi are concentrated in the flowering period, resulting in the similar ripening periods of fruits and are concentrated in the short term. “Chief scientist of the National Lychee Longan Industry Technology System and Huanong Researcher said.
According to the introduction, the paper conducted a systematic study on the lychee flowering regulation mechanism from the genome level, and found that a specific DNA sequence deletion in lychee may be an important factor in the formation of different flowering periods of lychee. This is very important for extending the lychee production period from 2 months to 4 months or even longer, reducing the seasonal sales pressure of fresh fruits, 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 tree crops of lychee and even the Non-Artaceae family.Babaylan 1990 cloth draw, and will also study tropical crops around the world. href=”https://comicmov.com/”>Babaylan 1990 cloth draw and basic research on world agriculture are of great reference value. “Li Jianguo said that Babaylan 1990 cloth draw This further consolidated my country’s international leadership in lychee research, narrowing lychee, citrus, apples, and grapes.tps://comicmov.com/”>Cinema 1950 witch cloth drawThe gap in research levels in other bulk fruit trees has achieved the initial goal of leapfrog improvement in the basic biology research level of litchi.
