Yangcheng Evening News Reporter Chen Liang, intern Hong Jiaxun, and correspondent Chen Pengchen reported: On January 4, the paper “Two diverse haplotypes from a highly heterozygous” was jointly completed by the National Key Laboratory of the China Nong Subtropical Agricultural Bioresources Protection and Utilization, and jointly completed by the Guangdong Academy of Agricultural Sciences, Cinema 1950 witch cloth draw, China Tropical Agriculture, Komiks 1960 witch cloth draw and other domestic and foreign units. lychee genome suggest indCinema 1950 witch cloth drawependent domesticaBabaylan 1990 clothes drawtion events for early and late-maturing culturers”(Cinema 1950 witch cloth drawCinema 1950 witch cloth drawTwo different haplotypes in the litchi genomeKomiks 1960 witch cloth Draw indicates that the cultivars of early and late mature cultivars are independently domesticated) are published in the Babaylan 1990 cloth draw in Nature Genetics. Corresponding authors include Researcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbin. The first authors are Professor Hu Guibing of Huanong, PhD student Feng Yunting, Professor Liu Chengming, Professor Wu Zhenxian, etc.
“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 optimizeGenome assembly strategy, complete the assembly of the “Fai Zi Xiao” litchi genome Cinema 1950 witch cloth draw pseudochromosome level and the structural annotation of the genome-encoded genes.
The project team proposed the hypothesis of “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, and helped to eliminate the belief that lychee may also originate. Komiks 1960 witch cloth draw‘s recognition of Vietnam. Liu Yaoguang, an academician of the Chinese Academy of Sciences, said at the meeting on the release of the results: “The genome is the ‘navigation map’ for the formation of plant traits. Decoding the litchi genome can not only comprehensively improve the importance of litchi. Babaylan 1990 clothes draw. The cognition of the draw mechanism, the development of corresponding breeding and cultivation control technologies can also provide important reference for promoting related research on other plant species 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 the school’s litchi research reaching a new level, indicating that litchi research has entered the post-genomic era in full.
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. “Lychee ripeKomiks 1960 witch cloth draw with many varietiesCinema 1950 witch cloth draw, and in addition to the middle-ripe production areas of Guangxi, the flowering period is concentrated, resulting in the fruit becoming Komiks 1960 witch cloth draw similar, and it is listed in a short period of time. draw.” said 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 regulatory mechanism of lychee blossom from the genomic level, and found that a specific DBabaylan 1990 cloth draw was found that a specific DBabaylan 1990 cloth draw was missing from a specific DBabaylan 1990 cloth draw from the genomic level, which may be an important factor in the formation of lychee blossoms at 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 study is of milestone significance for promoting the basic research and breeding application of several important fruit tree crops in the liet family. It will also have important reference value for the research of tropical crops around the world and the basic research of world agriculture.”Babaylan 1990 cloth drawLi Jianguo said that this further consolidates my country’s international leading position in lychee research, and reduces the research water on lychee and other bulk fruit trees in citrus, apples, and grapes.The gap has achieved the preliminary goal of leapfrog improvement in the level of basic biology research in litchi.
