四、报告人简介
张维肖，四川农业大学作物遗传育种专业博士研究生，预计 2026 年 12 月毕业，师从卢艳丽教授、冯宣军副教授。研究方向聚焦玉米抗病与抗逆分子机制，形成了 “基因挖掘 — 信号通路 — 功能验证 — 育种应用” 的全链条研究范式。
抗病研究层面，系统解析玉米受镰孢菌侵染引发穗腐病、茎腐病的抗性分子机制，首次证实 MPEL1-MAPK16-JAZ20 级联通路在多种病害防御中的作用，同时阐明组胺是红光提升玉米抗轮枝镰孢菌能力的关键物质；抗逆方向上，深入解析 LBD 转录因子家族 II 类成员在玉米、拟南芥干旱胁迫应答过程中的功能与分子调控机理。
代表性成果：
以共同第一作者（导师一作）身份在《The EMBO Journal》刊发研究，阐明 MPEL1 协同 MAPK16 调控玉米抵御镰孢菌的分子机制，为玉米广谱抗病育种提供新理论与关键基因资源；以共同第一作者在《iMeta》发表红光介导玉米抗轮枝镰孢菌关键化合物的挖掘成果，拓展光生物学与植物免疫交叉领域研究；另有多项以共同第一作者完成的研究发表于《The Plant Journal》《Plants-Basel》，聚焦 LBD 基因家族调控干旱胁迫响应方向。
五、报告内容预告
本次报告紧扣玉米抗病、抗旱育种两大前沿方向，依次介绍玉米抗镰孢菌病害分子调控通路、红光诱导玉米抗病的代谢调控机理、LBD 转录因子调控干旱应答的分子网络，同时讲解基因功能验证体系以及抗病抗逆性状在分子育种中的落地思路，可为玉米抗性育种、作物逆境分子生物学领域的相关研究提供理论参考。

IV. Biographical Information of the Reporter
Zhang Weixiao is a doctoral student majoring in Crop Genetics and Breeding at Sichuan Agricultural University. She is expected to graduate in December 2026 and is supervised by Professor Lu Yanli and Associate Professor Feng Xuanjun. Her research focuses on the molecular mechanisms of disease resistance and stress tolerance in corn, forming a complete research paradigm of "gene mining - signaling pathway - functional validation - breeding application".
In the aspect of disease resistance research, she systematically analyzed the molecular mechanism of resistance of corn to stem rot and stem blight caused by Fusarium infection, and for the first time confirmed the role of the MPEL1-MAPK16-JAZ20 signaling pathway in the defense against various diseases. At the same time, she clarified that histamine is the key substance for red light to enhance the resistance of corn to Rhizoctonia solani. In the direction of stress tolerance, she deeply analyzed the functions and molecular regulatory mechanisms of the II-class members of the LBD transcription factor family in the drought stress response processes of corn and Arabidopsis thaliana.
Representative achievements:
As the co-first author (with the supervisor as the first author), she published a study in The EMBO Journal, clarifying the molecular mechanism of MPEL1 collaborating with MAPK16 to regulate corn's resistance to Fusarium, providing new theories and key gene resources for broad-spectrum disease resistance breeding of corn; as the co-first author, she published the research results of the mining of key compounds for corn's resistance to Rhizoctonia solani mediated by red light in iMeta, expanding research in the intersection of photobiology and plant immunity; and she has also completed multiple studies as the co-first author and published them in The Plant Journal and Plants-Basel, focusing on the direction of regulating drought stress responses by the LBD gene family.
V. Report Content Preview
This report focuses on the two cutting-edge directions of corn disease resistance and drought tolerance breeding. It successively introduces the molecular regulatory pathway of corn's resistance to sclerotinia disease, the metabolic regulatory mechanism of red light-induced corn resistance, and the molecular network of LBD transcription factors regulating drought response. At the same time, it explains the gene function verification system and the implementation ideas of disease and stress resistance traits in molecular breeding. This can provide theoretical references for corn resistance breeding and related research in the field of crop stress molecular biology.
