Recently，The internationally renowned academic journal New PhytologistN published bet365 online games an article entitled "Chromosome-scale genome assembly and insights into the metabolome and gene regulation of leaf color transition in an important oak species, Quercus dentata” research paper，Analysis of the chromosome-level genome of an important Quercus plant and revealing the regulatory mechanism of its autumn leaf color transition。This research was completed by the urban forestry team of our school and Beijing Forestry University，Jointly train doctoral student Wang Wenbo、Associate Professor He Xiangfeng and doctoral student Yan Xuemei are the co-first authors of the paper，Professor Leng Pingsheng of our school、Professor Hu Zenghui and Professor Mao Jianfeng of Beijing Forestry University are the co-corresponding authors，Professor Wang Wenhe of our school、Associate Professor Wu Jing and others also participated in this research work。bet365 bet365 online games sports bettingThis research has been approved by the National Key R&D Program、Beijing Municipal Education Commission-Beijing Natural Science Foundation Joint Project and Beijing Municipal Education Commission Ecological Restoration Project Interdisciplinary Innovation Project Funding。

Quake (Quercusdentata) widely distributed in Northeast Asia，Is an important forest establishment species in North China and Northeast my country，its wood、Acorn、The blades have high utilization value。Its leaves are large and unique in shape，Autumn leaves are red，Also known as Chinese red oak，Widely used in urban and rural greening landscape construction，However, there is still a lack of in-depth research on the genetic basis and genetic diversity of oak trees’ excellent traits。The autumn color change of trees is often accompanied by chlorophyll degradation and anthocyanin synthesis during leaf senescence，Under the influence of environmental signals such as low temperature and light changes in autumn，The important scientific question of whether the two processes of leaf senescence and coloration are coupled and how they are coordinated is still unclear。

This study combines Nanopore long-read sequencing and Hi-C technology，A high-quality genome assembly of Quercus spp. was obtained (893.54 Mb) and feature notes，Conducted comparative genome analysis and homologous species collinearity analysis，Identification of metabolic pathways related to flavonoid synthesis and chlorophyll degradation pathways during the autumn color change of oak trees。Joint analysis of transcriptome and metabolome in five stages of bet365 online games change，Constructed a temporal gene co-expression regulatory network for chlorophyll degradation and anthocyanin synthesis during the color change of oak leaves，And verified the key gene regulation model based on yeast single and double hybrid experiments。This study establishes the role of NAC in the color transformation process of oak leaves，MYB，Coordinated regulatory network of chlorophyll degradation and anthocyanin synthesis with HY5 transcription factor as the core，Revealing the molecular regulatory mechanism of autumn leaf discoloration and senescence，Lay the foundation for research on the adaptability and genome function of Quercus。
