生长素是一种重要的生长调节剂，它调控植物的发育和对环境扰动的反应。它在许多发育过程中发挥着核心作用，从胚胎发育到器官衰老，并且是植物与环境相互作用的关键，包括对生物和非生物刺激的反应。与生长素一样引人注目的是，它不是单独作用，而是寻求其他内源信号的帮助或被其他内源信号所请求，包括植物激素脱落酸、油菜素类固醇、细胞分裂素、乙烯、赤霉酸、茉莉酸、水杨酸和木内酯。生长素和其他激素之间的相互作用发生在多个水平上：激素相互调节彼此的合成、运输和/或反应；不同途径的激素特异性转录调节因子在物理上相互作用和/或汇聚在共同的靶基因上；等等。然而，我们对这种串扰的理解仍然是零散的，只有几块巨大的谜团牢固地确立了下来。在这篇综述中，我们提供了一个涉及生长素的激素相互作用的复杂性的一瞥，强调了我们目前的理解是多么的不完整。
Auxin is a crucial growth regulator that governs plant development and responses to environmental perturbations. It functions at the heart of many developmental processes, from embryogenesis to organ senescence, and is key to plant interactions with the environment, including responses to biotic and abiotic stimuli. As remarkable as auxin is, it does not act alone, but rather solicits the help of, or is solicited by, other endogenous signals, including the plant hormones abscisic acid, brassinosteroids, cytokinins, ethylene, gibberellic acid, jasmonates, salicylic acid, and strigolactones. The interactions between auxin and other hormones occur at multiple levels: hormones regulate one another's synthesis, transport, and/or response; hormone-specific transcriptional regulators for different pathways physically interact and/or converge on common target genes; etc. However, our understanding of this crosstalk is still fragmentary, with only a few pieces of the gigantic puzzle firmly established. In this review, we provide a glimpse into the complexity of hormone interactions that involve auxin, underscoring how patchy our current understanding is.
