Invertase (INV) hydrolyzes sucrose into glucose and fructose, thereby playing key roles in primary metabolism and plant development. Based on their pH optima and sub-cellular locations, INVs are categorized into cell wall, cytoplasmic, and vacuolar subgroups, abbreviated as CWIN, CIN, and VIN, respectively. The broad importance and implications of INVs in plant development and crop productivity have attracted enormous interest to examine INV function and regulation from multiple perspectives. Here, we review some exciting advances in this area over the last two decades, focusing on (1) new or emerging roles of INV in plant development and regulation at the post-translational level through interaction with inhibitors, (2) cross-talk between INV-mediated sugar signaling and hormonal control of development, and (3) sugar- and INV-mediated responses to drought and heat stresses and their impact on seed and fruit set. Finally, we discuss major questions arising from this new progress and outline future directions for unraveling mechanisms underlying INV-mediated plant development and their potential applications in plant biotechnology and agriculture.
转化酶（INV）将蔗糖水解为葡萄糖和果糖，从而在植物的初级代谢和发育中发挥关键作用。根据最适 pH 值和亚细胞定位，INV 可分为细胞壁、细胞质和液泡亚群，分别缩写为 CWIN、CIN 和 VIN。INV 在植物发育和作物生产力中的广泛重要性和意义引起了人们极大的兴趣，从多个角度研究 INV 的功能和调控。本文回顾了过去二十年该领域的一些令人兴奋的进展，重点介绍了（1）通过与抑制剂相互作用，INV 在植物发育和翻译后水平调控中的新作用或新出现的作用，（2）INV 介导的糖信号与激素对发育的调控之间的串扰，以及（3）糖和 INV 介导的对干旱和热胁迫的响应及其对种子和果实形成的影响。最后，我们讨论了这一新进展所带来的主要问题，并概述了阐明 INV 介导的植物发育机制及其在植物生物技术和农业中的潜在应用的未来方向。
