摘要

开花植物的繁殖成功直接影响作物产量,对环境变化很敏感。深入了解作物生殖发育如何适应气候变化,对于确保全球粮食安全至关重要。番茄不仅是一种高价值的蔬菜作物,也是研究植物生殖发育的模式植物。番茄作物是在全世界高度多样化的气候条件下种植的。杂交品种的定向杂交提高了产量和抗非生物胁迫能力;然而,番茄生殖,尤其是雄性生殖发育,对温度波动很敏感,这可能导致雄性配子体流产,对坐果产生不利影响。本文综述了影响番茄雄性生殖器官发育和对非生物胁迫反应的细胞学特征以及遗传和分子途径。我们还比较了番茄和其他植物相关调控机制的共同特征。总之,这篇综述强调了在番茄杂交育种计划中表征和利用基因雄性不育性的机遇和挑战。

Molecular regulation of tomato male reproductive development

Molecular regulation of tomato male reproductive development

The reproductive success of flowering plants, which directly affects crop yield, is sensitive to environmental changes. A thorough understanding of how crop reproductive development adapts to climate changes is vital for ensuring global food security. In addition to being a high-value vegetable crop, tomato is also a model plant used for research on plant reproductive development. Tomato crops are cultivated under highly diverse climatic conditions worldwide. Targeted crosses of hybrid varieties have resulted in increased yields and abiotic stress resistance; however, tomato reproduction, especially male reproductive development, is sensitive to temperature fluctuations, which can lead to aborted male gametophytes, with detrimental effects on fruit set. We herein review the cytological features as well as genetic and molecular pathways influencing tomato male reproductive organ development and responses to abiotic stress. We also compare the shared features among the associated regulatory mechanisms of tomato and other plants. Collectively, this review highlights the opportunities and challenges related to characterizing and exploiting genic male sterility in tomato hybrid breeding programs.
