“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 Illunina to optimize the genome assembly strategy to complete the assembly of pseudochromosomes of the litchi genome and structural annotation of the genome encoding gene. The project team proposed the hypothesis of “one center of origin, two independent domestication events” to make the cloudf=”https://comicmov.com/”>Babaylan is the only center of origin of lychees in the world. Cinema provides genomic evidence and helps eliminate the cognition that some foreign scholars believe that lychees may also originate in Vietnam. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the results press conference: “The genome is the ‘navigationBabaylan figure’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the understanding of the important economic trait formation mechanism for litchi, develop corresponding breeding and cultivation regulation technologies, but also promote other dysfunctional plants such as Cinema family href=”https://comicmov.com/”>Komiks related research on longan provides important reference.” Liu Yahong, principal of Huanong, said that the high-level paper published by the school’s team in “Nature-Genetics” marks a new height in the school’s lychee research, heralding that the research of the lychee family has fully entered the post-genomic era.
Revealing the flowering regulation mechanism
Improving the benefits of lychee planting
Fresh lychee fruits are mainly concentrated from May to July. There is a seasonal surplus of fruits in Cinema production, which seriously affects the economic benefits of lychee branch planting. “There are many medium-ripe varieties of lychees, and the middle-ripe production areas of Guangxi are concentrated in the flowering period, 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. According to reports, the paper conducted a systematic study on the regulation mechanism of lychee blossom from the elementary level, and found that a specific DNA sequence was missing in lychee., may be an important factor in the formation of lychee during different flowering periods. This is very important for extending the lychee production period from 2 months to 4 months or even longer. Komiks reduces seasonal sales pressure on fresh fruits and improves 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 family of vasodil family. It will also have important reference value for the research of tropical crops around the world and the basic research of world agriculture.Komiks“Komiks“Komiks“Komiks 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 a preliminary goal of leapfrog improvement in the level of basic biology research in lychee. href=”https://comicmov.com/”>Babaylan tag.
