Brief bio: I started my research when I joined Prof. Yang Jinghua’s lab in 2018 at Zhejiang University with a focus on the mechanism of watermelon resistance to Cucumber green mottle mosaic virus (CGMMV). In this study, we mapped a WPRb gene that could affect callose deposition after CGMMV infection, which contributes to resistance or tolerance to CGMMV in plants. At the same time, I took part in the breeding of viruses resistance watermelon varieties and constructed several viruses resistant populations. I also developed some KASP molecular markers for field-assisted breeding of watermelon and melon. In addition, a set of efficient genetic transformation systems for watermelon was optimized, which laid the foundation for the identification of functional genes in watermelon. Currently, the host factors associated with CGMMV are still being explored, and it is expected to provide new ideas for the breeding and improvement of watermelon in the future.

个人简介：我于2018年进入浙江大学攻读研究生，师从杨景华教授，硕博期间主要从事西瓜抗黄瓜绿斑驳花叶病毒病抗病机制研究。该研究利用正向遗传学手段定位到一个WPRb基因，在植物感染黄瓜绿斑驳花叶病毒后，WPRb通过影响胼胝质的沉积使得植物表现出抗病或耐病。同时我开展了西瓜抗病毒病品种选育工作，构建了多个抗病群体，开发了数个西甜瓜KASP分子标记用于田间辅助育种。此外，优化了一套西瓜高效遗传转化体系，为西瓜功能基因鉴定奠定了基础。目前，仍然在挖掘与黄瓜绿斑驳花叶病毒病相关联的寄主因子，期待未来能够为西瓜抗病毒病育种改良提供新思路。
