报告题目：植物表皮毛：一场“毛发革命”背后的基因暗战

报告摘要：

 植物表皮毛不仅是抵御生物与非生物胁迫的重要屏障，分泌型腺毛还能合成具有经济价值的各种植物次生代谢物。作为植物表皮细胞的特化结构之一，也是研究细胞分化和命运决定的理想模型。植物HD-ZIP IV家族中多个成员基因在多种植物的表皮毛形成中的具有较为保守的功能，但其成员间的功能分化、协同调控及激素响应机制仍不十分清晰。此外，目前对表皮毛的生物学功能认知相对局限，更多生物学功能有待挖掘。报告人团队最近研究发现，番茄果实毛是影响果实采后的重要因子，有望开发成为延长采后货架期新靶标。

TITLE：Plant trichomes: The genetic battle behind the 'trichome formation'

ABSTRACT：

     Plant trichomes serve as an important barrier against biotic and abiotic stresses, while secretory glandular trichomes can synthesize various economically valuable secondary metabolites. As a specialized structure of plant epidermal cells, they serve as an ideal model for studying cell differentiation and fate determination. It has been determined that multiple genes within the plant HD-ZIP IV family exhibit conserved functions in the formation of trichomes across various plant species. However, the functional differentiation, synergistic regulation, and hormonal response mechanisms among its members remain poorly understood. Additionally, the current understanding of the biological functions of trichomes is relatively limited, with many biological functions yet to be explored. Our recent research has revealed that tomato fruit trichomes are a key factor influencing post-harvest fruit quality, offering potential as a new target for extending postharvest shelf-life.
