Plant response to pathogens attacks generally comes at the expense of growth. Defense priming is widely accepted as an efficient strategy used for augmenting resistance with reduced fitness in terms of growth and yield. Plant-derived small molecules, both primary as well as secondary metabolites, can function as activators to prime plant defense. Amino acids and their derivatives regulate numerous aspects of plant growth and development, and biotic and abiotic stress responses. In this review, we discuss the recent progress in understanding the roles of amino acids and related molecules in defense priming and their link with plant growth. We also highlight some of the outstanding questions and provide an outlook on the prospects of 'engineering' the tradeoff between defense and growth in plants.
植物对病原体攻击的反应通常以牺牲生长为代价。防御预激活被广泛认为是一种有效的策略，用于在生长和产量方面降低适应性的情况下增强抗性。植物衍生的小分子，包括初级和次级代谢物，可作为激活剂来启动植物防御。氨基酸及其衍生物调节植物生长和发育以及生物和非生物胁迫反应的众多方面。在这篇综述中，我们讨论了在理解氨基酸和相关分子在防御预激活中的作用及其与植物生长的联系方面的最新进展。我们还强调了一些悬而未决的问题，并展望了在植物中“设计”防御和生长之间权衡的前景。
