Babaylan cloth lychee birth period is expected to be extended, Huanong’s latest research deciphers the gene code of lychee

Yangcheng Evening News Reporter Komiks 1960 witch cloth draw Chen Liang, intern Hong Jiaheng, and correspondent Chen Pengchen reported: On January 4, led by the National Key Laboratory of Conservation and Utilization of Subtropical Agricultural Bioresources in Huanong, jointly with Guangdong Province Agricultural Science and Technology Department Babaylan 1990 clothes The paper “Two divergent hBabaylan 1990 cloth drawaplotypes from a highly heterozygous lychee genome suggest indepeBabaylan 1990 cloth drawon events forBabaylan 1990 cloth drawndent domesticatiBabaylan 1990 cloth drawon events forKomiks 1960 witch cloth draw early and late-maturing cultivars” (two different haplotypes in the high heterozygous litchi genome indicate that the early and late-maturing cultivars are domesticated independently) 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 Cinema 1950 witch cloth draw, Professor Liu Chengming, Professor Wu Zhenxian, etc. Cinema 1950 witch cloth draw

“Decode” litchi genome

Propose the origin domestication hypothesis

Komiks 1960 witch cloth drawIn this study, scientists used the latest gene sequencing data of the second-generation Illunina and other genes, and completed the “Father Xiao” litchi genome false staining by optimizing the genome assembly strategy. The assembly of drawbody level, structural annotation of gene encoding genes in the Cinema 1950 witch cloth draw group. The project team proposed the hypothesis of “one center of origin, two independent domestication events” of lychee, which provided genomic evidence for Yunnan being the only lychee originating in the world, which helped to 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 press conference on the results of Komiks 1960 witch cloth draw: “The genome is the ‘navigation map’ for the formation of plant traits. Cinema 1950 witch cloth draw decoding the litchi genome can not only comprehensively improve the importance of litchi rituals. DrawThe understanding of the mechanism of formation of economic traits, and the development of corresponding breeding and cultivation Komiks 1960 witch cloth draw control technology can also provide important reference for promoting related research on other trouble-free plants such as longan. “Hua Nong Principal Liu Yahong said that the high-level paper published by the school team in “Nature-Genetics” marks a new height for the school’s lychee research, indicating that the lychee scientific research has entered the post-genomic era.

Fresh lychee fruits are mainly concentrated from May to July, and there is often seasonal oversupply of fruits in production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychee, and the two and Guangxi are medium-ripe production areas in the middle latitude, and the flowering period is concentrated, resulting in the similar ripening periods of fruits. In a short period of time Cinema 1950 witch cloth draw is listed in a centralized manner. “Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and a researcher at Huanong, 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 Komiks 1960 witch cloth draw DNA sequence deletion in lychee may be an important factor in the formation of different flowering periods of lychee. This will extend the lychee production period from 2 months to 4 months or even longer, and reduce the seasonal sales pressure of fresh fruits. Draw and improve the efficiency 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 Novada Family. At the same time, the Komiks 1960 witch cloth draw will have important reference value for the research on tropical crops around the world and the basic research on world agriculture. “Li Jianguo said that this further consolidates my country’s international leadership in lychee research, and reduces the research water on lychee and other bulk fruit trees, such as lychee, apple, and grapes.The gap has realized the preliminary goal of leapfrog improvement in the basic biology research level of litchi.
