Litchi delivery period is expected to be extended. Huanong’s latest research Babaylan cloth deciphers the lychee gene code

Corresponding authors include Researcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbinyan Babaylan 1990 cloth draw, etc. Cinema 1950 witch cloth drawThe authors are Professor Hu Guibing of Huanong, PhD student of Feng Yunting, Professor Liu Chengming, Professor Wu Zhenxian, etc.

“Decode” the litchi genome

Propose the origin and domestication hypothesis

In this study, scientists used the latest genome sequencing data such as the second generation of Illunina to optimize the genome assembly strategy of Komiks 1960 witch cloth draw to complete the assembly level of the pseudochromosome of the litchi genome and the structural annotation of the genome encoding gene.

The project team proposed the hypothesis of “one center of origin, two independent domestication events”, providing genomic evidence for the only center of origin of litchi in the world, which helped to eliminate the belief that litchi in some foreign scholars may also originate from Vietnam. cognition of draw. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the press conference on the “genome”: “The genome is the ‘navigation map’ for the formation of plant traits. Decoding the litchi gene gene Cinema 1950 witch cloth draw can not only comprehensively improve the understanding of the mechanism of forming important economic traits of litchi, develop corresponding breeding and cultivation control technologies, but also provide important considerations for promoting related research on other mortal-free plants such as longan.” Liu Yahong, president of Huanong, said href=”https://comicmov.com/”>Cinema 1950 witch cloth drawThe schoolKomiks 1960 wiThe high-level paper standard published by the tch cloth draw team in Nature Genetics is to achieve a new high in the school’s lychee research, indicating that lychee research has entered the post-genomic era.

The market launch of fresh lychee fruits is mainly concentrated from May to July. There is often a seasonal surplus of fruits during production, which seriously affects the economic benefits of lychee planting. Komiks 1960 witch cloth draw “There are many medium-ripe varieties of lychees, and the two and Guangxi are medium-ripe production areas in the middle latitude. 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, the paper conducted a systematic study on the litchi flowering regulation mechanism from the genome level, and found that a specific DNA sequence deletion in litchi may be an important factor in the formation of litchi different flowering stages. This is very important for extending the lychee production period from 2 months to 4 months or even longer, reducing seasonal sales pressure on fresh fruits, and improving the benefits of lychee planting.

Babaylan 1990 cloth draw“This study has a milestone significance for promoting the basic research of several important fruit crops of lychee and even the Novada family, as well as the breeding application of Babaylan 1990 cloth draw, and will also provide basic research on tropical crops worldwide and the world’s agricultureIt has important reference value. “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 in the basic biological research level of lychee.
