“Decoding” the litchi genome
Komiks proposed the origin and domestication hypothesis
In this study, scientists used the latest genome sequencing data such as the second generation Illunina to complete the assembly of pseudochromosome levels of the litchi genome and the structural annotation of the genome encoding genes by optimizing the genome assembly strategy. The project team proposed the hypothesis of “one center of origin, two independent domestication events” of lychee, providing genomic evidence for Yunnan to be the only center of origin of lychee in the world, which helps 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 mechanism of forming important economic traits of litchi, but also develop corresponding breeding and planting regulatory technologies, but also promote related research on other plants of the family zodiac family such as longan. href=”https://comicmov.com/”>Babaylan research provides important reference. “Hua Nong Principal Liu Yahong said that the high-level paper published by the school’s team in “Nature-Genetics” marks a new height for the school’s lychee research, indicating that lychee scientific research has entered the post-genomic era in full.
Revealing the Flowering TemperatureCinema Control Mechanism
Improving the benefits of lychee planting
The market of fresh lychee fruits is mainly concentrated from May to July. There is often a seasonal surplus of fruits in production, which seriously affects the economic benefits of lychee planting. “There are many medium-ripe varieties of lychees, and the medium-ripe products of Guangxi are mid-latitude Komiks District, the flowering period is concentrated, resulting in the similar ripening periods of the fruits and is launched in a short period of time. “Chen Houbin, chief scientist of the National Lychee Longan Industry Technology System and researcher of Huanong.
According to reports, the href=”https://comicmov.com/”>Babaylan‘s paper systematically conducted a systematic study on the litchi flowering regulation mechanism from the genome level, and found that a specific DNA sequence missing in litchi may be an important factor in the formation of different flowering periods of litchi. This is very important for extending the litchi yield period from 2 months to 4 months or even longer, reducing the seasonal sales pressure of fresh fruits, and improving the benefits of litchi planting.
“This study is of milestone significance for promoting the basic research and breeding application of several important fruit tree crops of litchi and even the family of litchi 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 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 realizes the preliminary goal of leapfrog improvement in the basic biology research level of lychee.
