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 lychee genome sugCinemagest independent domestication events for early and late-maturing cultivaKomiksrs” (highly heterozygous Two different haplotypes in the Babaylan litchi genome indicate that the early and late mature cultivars are domesticated independently) published in Nature GenKomiksetics. Corresponding authors include Researcher Li Jianguo, Professor Xia Rui and Researcher Chen Houbin. The first authors are Professor Hu Guibing of Huanong, Professor Feng YuntingboKomiksSchool, Professor Liu Chengming, Professor Wu Zhenxian, etc.
“Decode” the litchi genome
Propose the origin and domestication pseudo-animation Cinema said
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 the structural annotation of the genome-encoded genes. Komiks
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, and helped to eliminate the cognition that some foreign scholars believe that lychee may also originate from Vietnam. Cinema research provides important references.” 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, indicating that lychee scientific research has entered the post-genomic era.
Revealing the flowering regulation mechanismBabaylan
Improving the benefits of litchi branch planting
Fresh litchi fruits on the Cinema city are mainly concentrated from May to July. Seasonal surplus of fruits often occurs in production, which seriously affects the economic benefits of litchi planting. “There are many medium-ripe varieties of lychees, and the medium-ripe production areas of Guangxi are concentrated in the middle-latitude Cinema, which leads to the similar ripening periods of fruits, and are listed in a short period of time.” Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and researcher of Huanong Cinema. According to reports, the paper conducted a systematic study on the litchi flowering regulation mechanism from the genome level and found that a specific DNA sequence deletion in litchi may be an important factor leading to the formation of litchi in different flowering stages. This will extend the lychee birth period from 2 months to 4 months or even longer, it is very important to reduce the seasonal sales pressure of fresh fruits and improve the efficiency of lychee planting. “This research is of great significance to promoting the basic research and breeding application of several important fruit crops of Cinema to the Wuwan Family. It will also have important reference value for the research of tropical crops around the world and the basic research of world agriculture.” Li href=”https://comicmov.com/”>Babaylan 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 in citrus, apples, and grapes, and achieves the preliminary goal of leapfrog improvement in the basic biology research of lychee.
