“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 IlluninaKomiks to optimize the genome assembly strategy to complete the pseudochromosome level of the litchi genome “Fei Zixiao”<a href="https://comicmov.com/”>Cinema assembly and structural annotation of genome-encoded genes.
The project team proposed the hypothesis of lychee “one center of origin, two independent domestication events”, which provided genomic evidence for Yunnan to be the only center of origin of lychee in the world, which helped to eliminate the cognition that some foreign scholars believe that lychee may also originate in Vietnam.
Academician Liu Yaoguang of the Chinese Academy of Sciences said at the results press conference: “Genome is a ‘navigation map’ for the formation of plant traits. Decoding 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 regulation technologies, but also provide important reference for promoting related research on other mortality-free plants such as longan. “Hua Nong Principal Liu Yahong said that the high-level paper published by the school’s team in “Nature-Genetics” marks a new height for the school’s lychee research and indicates that lychee research has entered the post-genomic era.

Improving the benefits of lychee planting
The market of fresh lychee fruits is mainly concentrated from May to July. There are often seasonal surplus of fruits in Cinema during production, which seriously affects the economic benefits of lychee planting. “LycheeBabaylan with many medium-ripe varieties. In addition, the middle-ripe production areas of Guangxi are concentrated in the middle-latitude, resulting in the similar ripening periods of the fruits and are concentrated in a short period of time. “Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and a researcher at Huanong, said.
According to the genomic level, the paper conducted a systematic study on the lychee flowering regulator system, and found that a specific DNA sequence in lychee is missing,It can be an important factor in the formation of lychee during the same flowering period. 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 fruit season and improving the benefits of lychee cultivation. “This research is of milestone significance for promoting the basic research and breeding application of lychee and even several important species of Cinema fruit crops, as well as breeding applications, 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 consolidates my country’s international leadership 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 level of basic biological research in lychee.
