2021年8月2日，我室孙蒙祥教授课题组在Journal of Experimental Botany 杂志发表了题为Autophagy in sexual plant reproduction: new insights for thought 的观点论文，文章主要对自噬在植物生殖中的具体作用进行了论述，这将为进一步的研究提供新的思路。
自噬是一种降解受损或不需要的细胞，并回收其成分的机制。在过去的几十年里，自噬的研究已经从酵母扩展到哺乳动物和植物，并且调节自噬的核心机制在不同物种中似乎是保守的。在植物中，自噬在应对胁迫条件方面具有重要作用，也有助于植物的正常发育，尤其是在植物的繁殖过程中。 不同植物谱系的最新进展揭示了植物生殖中，自噬的几个关键方面。首先，负责自噬体形成的核心ATG 基因在不同的植物谱系中是保守的，存在于单细胞绿藻到被子植物。其次，自噬对植物生殖的贡献因物种而异。最后，自噬参与细胞命运的决定和雄配子体的育性。 Compartmental autophagy-mediated cytoplasm deletion is essential for compatible pollen germination. 本文基于最近对自噬作用和分子机制的理解，重点论述了自噬在植物生殖中的具体作用，这为进一步研究提供了新的思路。原文链接：https://doi.org/10.1093/jxb/erab366
