“Komiks decoding” litchi genome
proposes the origin and domestication hypothesis
In this study, the scientists used the latest genome sequencing data such as the second generation Illunina to optimize the genome assembly strategy to complete the assembly level of the pseudochromosome of the litchi genome and the structural annotation of the genome encoding gene. </pThe 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. Komiks helped to eliminate the cognition that some foreign scholars believe that lychee may also originate in Vietnam.
Academician of the Chinese Academy of Sciences Liu Yaoguang said at the results press conference: “The genome of “Komiks” is the “navigation of plant trait formation. Decoding the litchi genome can not only comprehensively improve the understanding of the formation mechanism of 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 plants without mortality plants such as longan.” Liu Yahong, principal of Huanong, said that the school’s team is in The high-level paper published in Nature-Genetics marks a new high in the school’s lychee research, indicating that lychee research has entered the post-genomic era in full.
Revealing the secret of opening the flower regulation mechanism of BabaylanImproving the benefits of lychee planting
BabaylanThe market is mainly concentrated from May to July. Fresh fruits in lychee are often in production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychees, and the two and Guangxi are medium-ripe production areas at the mid-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 different flowering periods of litchi. This is for putting lycheeBabaylan has been extended from 2 months to 4 months or even longer. It is very important to reduce the seasonal sales pressure of fresh fruits and improve the efficiency of lychee planting. “This Komiks study is of milestone significance for promoting the basic research and breeding application of several important fruit tree crops of Cinema and even the Non-Africa seedlings. It 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 the research of litchi, narrows the gap in research levels between litchi and other bulk fruit trees in citrus, apples, and grapes, and achieves the preliminary goal of leapfrog improvement in the research level of basic biology of litchi.
