“Decode” the litchi genome
Propose the origin and domestication hypothesis
In this study, scientists used the latest genome sequencing data such as second-generation Illunina to optimize genome assembly strategiesomittedly, complete the assembly of the pseudochromosome level of the litchi genome and the annotation of the genome Cinema structure of the gene encoding.
The project team proposed the hypothesis of lychee “one center of origin, two independent domestication events”, which provided genomic evidence for Yunnan being 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. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the results press conference: “The genome is the ‘Komiks navigation map’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the understanding of the litchi important economic traits, develop corresponding breeding and cultivation regulation technologies, but also provide important reference for promoting related research on other illicholae plants such as longan.” Liu Yahong, principal of Huanong, said that the high-level paper published by the school’s team in “Nature-Genetics Cinema” marks a new height in the school’s litchi research, which indicates that the litchi research has entered the full entry of litchi research. href=”https://comicmov.com/”>Komiks Group era.
Revealing the regulatory mechanism of floweringBabaylanBabaylan
Improving the benefits of lychee planting
The 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 in addition, the middle-ripe production areas of Guangxi are concentrated in the middle-latitude Cinema period, 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 Dragon Eye Industry Technology System and researcher of Huanong.
According to the genomic level, the paper has carried out a systematic approach to the regulation mechanism of lychee blossom from the genomic level.Komiks‘s general study found that a specific DNA sequence missing in lychees may be an important factor in the formation of lychees in different flowering periods. This is very important for extending the lychees’ yield period from 2 months to 4 months or even longer, reducing seasonal sales pressure on fresh fruits, and improving the benefits of lychees’ planting. “This study is of milestone significance for promoting the basic research and breeding application of several important fruit tree crops of lychees and even Babaylan’s family. href=”https://comicmov.com/”>Komiks 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 consolidated my country’s international leadership in lychee research, narrowed the gap in research levels between lychee and other bulk fruit trees in citrus, apples, and grapes, and achieved the initial goal of leapfrog improvement in the basic biology research level of lychee.
