“Decoded” litchi matrix Cinema proposed 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 pseudochromosome levels of the litchi genome and structural annotation of the gene encoding of the gene.
The project team proposed the hypothesis of “one center of origin, two independent domestication events”, which is that Yunnan is the only origin of lychee in the world.The Center provides gene Cinemaomic evidence, which helps to eliminate the perception that some foreign scholars believe that lychee may also originate from Vietnam. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the results press conference: “The genome is the ‘navigation map’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the understanding of the mechanism of economic trait formation in litchi, develop corresponding breeding and Komiks cultivation and regulation technologies, but also provide important reference for promoting related research on other plants of the family of no family, such as longan.” Liu Yahong, president of Huanong, said that the school team published in Nature-Genetics href=”https://comicmov.com/”>CinemaHigh-level papers mark a new height for the school’s lychee research and herald the full entry of the post-genomic era of lychee research.
Revealing the flowering regulation mechanism
Improving the benefits of lychee planting
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. “There are many medium-ripe varieties of lychees. In addition, the middle-ripe production areas of Guangxi are centralized in the middle-latitude. The flowering period of Komiks is a similar ripening period, which leads to the similar fruit ripening periods and is launched 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 genomic level and found that a specific DNA sequence of lychee, named Komiks in lychee is missing, which may be an important factor that causes the formation of lychee to be different flowering stages.m/”>Babaylan. 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 fruits in Cinema, and improving the efficiency of lychee planting. “This study is of milestone significance for promoting the basic research and breeding application of several important fruit trees in lychee and even the Non-Africa seedlings. It will also have important reference value for the research on tropical crops in the world and basic research on 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, and achieves the preliminary goal of lychee to improve the basic biology research level of lychee.
