This project aims to determine how genetic manipulation of cell wall invertase (CWIN) activity could regulate pollen germination, elongation and fruit set under heat stress using tomato as a model. Plant reproductive processes are highly susceptible to heat stress, which often leads to pollination failure and fruit and seed abortion, hence irreversible yield loss. Research has established that CWIN-mediated sugar metabolism and signaling may play crucial roles in pollen growth and fruit set under heat stress. The intended outcome is the generation of critical knowledge that will advance understanding on reproductive development under heat stress, thereby providing significant benefits, such as novel ideas and solutions for improving crop yield.

本项目旨在以番茄为研究对象，研究基因调控细胞壁转化酶（CWIN）活性对热胁迫下花粉萌发、伸长和坐果的影响。植物生殖过程极易受到热胁迫的影响，热胁迫往往导致授粉失败和果实和种子流产，从而导致不可逆转的产量损失。研究表明，cwin介导的糖代谢和信号传导可能在热胁迫下花粉生长和坐果过程中起重要作用。预期的结果是产生关键知识，这将促进对热胁迫下生殖发育的理解，从而提供显着的好处，例如提高作物产量的新想法和解决方案。
