Abstract

Small chemical molecules are attractive agents for improving the plant processes associated with plant growth and stress tolerance. Recent advances in chemical biology and structure-assisted drug discovery approaches have opened up new avenues in plant biology to discover new drug-like molecules to improve plant processes for sustained food production. Several compounds targeting phytohormone biosynthesis or signalling cascades were designed to alter plant physiological mechanisms. Altering Abscisic acid synthesis and its signalling process can improve drought tolerance, and the processes targeted are reversible. Molecules targeting cytokinin, Auxin, and gibberellic acid regulate plant physiological processes and can potentially improve plant growth, biomass and productivity. The potential of molecules may be exploited as agrochemicals to enhance agricultural productivity. The discovery of small molecules provides new avenues to improve crop production in changing climatic conditions and the nutritional quality of foods. We present the rational combinations of small molecules with inhibitory and co-stimulatory effects and discuss future opportunities in this field.

调节植物激素信号的小分子化学物质可以改变植物的生理过程,从而提高对压力的适应能力、生长能力和生产力。
小化学分子是改善与植物生长和抗逆性相关的植物过程的有吸引力的药物。化学生物学和结构辅助药物发现方法的最新进展为植物生物学开辟了新的途径,以发现新的类药物分子来改善植物生长过程,从而实现持续的粮食生产。一些针对植物激素生物合成或信号级联的化合物被设计出来,以改变植物的生理机制。改变脱落酸的合成及其信号传导过程可以提高耐旱性,而且所针对的过程是可逆的。针对细胞分裂素、叶黄素和赤霉素的分子可调节植物生理过程,并有可能改善植物的生长、生物量和生产力。这些分子的潜力可作为农用化学品加以利用,以提高农业生产力。小分子的发现为在不断变化的气候条件下提高作物产量和食品营养质量提供了新的途径。我们介绍了具有抑制和协同刺激作用的小分子的合理组合,并讨论了这一领域未来的机遇。
