Current Position: Beijing Genomics Institute (BGI), bioinformatics engineer

Education: 2018-2021 Master of Tree Genetics and Breeding, Beijing Forestry University.

Brief biography: From 2018 to 2121, I was studied in the Department of Tree Genetics and Breeding of Beijing Forestry University, and has been following Professor Yuepeng Song to conduct research on forest molecular breeding and genomics since entering in 2018, mainly focusing on leaf configuration and plasticity of Populus. After graduation, I worked at BGI, engaged in bioinformatics analysis. In this study, we profiled two distinct leaf morphology types (serrated and smooth) using the PHMF in two poplar species. A combined GWAS and eQTN mapping were applied to create a leaf morphology control module using data from Populus tomentosa and Populus simonii populations. Natural variation in leaf margins was associated with YAB11 transcript abundance in poplar, and the early termination of YAB11 translation led to the loss of positive regulation of NGAL1 and RBCL. In conclusion, in poplars, In poplar, YAB11-NGAL1 modules which is sensitive to environmental conditions regulate nature variation of poplar leaf serrations and increase stomatal density and light damage repair ability.

个人简历：2018-2121年就读于北京林业大学林木遗传育种学科，自2018入学以来始终跟随导师宋岳朋教授进行林木分子育种与基因组学的研究，主要方向为毛白杨叶片构型与可塑性。毕业后进入北京华大生命科学研究院从事生物信息学分析工作。本研究中，我们利用PHMF对两种杨树的叶片形态(锯齿状和光滑状)进行了分析。采用GWAS和eQTN图谱分析相结合的方法，利用毛白杨和小叶杨群体数据建立了叶片形态调控模块。发现杨树叶缘的自然变异与YAB11转录丰度相关，且YAB11提前翻译终止导致其失去了对NGAL1和RBCL的正调控。总之，在杨树中，对环境条件敏感的YAB11-NGAL1模块调节了杨树叶片锯齿的自然变化，提高了气孔密度和光损伤修复能力。
