“Decode” litchiCinemaGenome
Propose the hypothesis of origin and domestication
In this study, CinemaScientists use the latest genome sequencing data such as second-generation Illunina to optimize genome assemblyKomiks strategy Cinema, completing the assembly of pseudochromosome levels of the litchi genome and structural annotation of the 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 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 ‘navigation map’ for the formation of plant traits. 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 planting regulatory technologies, but also provide important reference for promoting related research on other plants of the family of no family, such as longan.” Liu Yahong, principal of Huanong, said that the high-level paper published by the school’s team in Nature-Genetics marks a new height for the school’s litchi research, which indicates that litchi scientific research has entered the post-genomic era.
Revealing the flowering regulation mechanism
Improving the benefits of lychee planting
Fresh lychee fruits are mainly concentrated in May to July, and there is often an overseasonal surplus in production during fruit season, which seriously affects the economic benefits of lychee 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 maturity periods of fruits and will be launched in a short period of time.” Chen Houbin, chief scientist of the national lychee industry technology system and researcher of Huanong.
According to reports, the paper BabaylanA systematic study was conducted on the regulatory mechanism of lychee blossom from the genomic level and found that a specific DNA sequence was missing in lychee. Komiks may be an important factor in the formation of lychee different flowering stages. This is very important for extending the lychee production period from 2 months to 4 months or even longer, reducing seasonal sales pressure on fresh fruits, and improving the benefits of lychee planting. “This research is of milestone significance for promoting the basic research and breeding application of important fruit tree crops in lychee and even several Babaylan, and will also have important reference value for tropical crops worldwide and basic research on world agriculture.” Li Jianguo said that this further consolidates my country’s international leadership in lychee research. href=”https://comicmov.com/”>Komiks narrowed the gap in research levels between lychees and other bulk fruit trees in citrus, apples, and grapes, and achieved the preliminary goal of leapfrog improvement in the basic biological research level of lychees.
