摘要

脱落酸(ABA)和乙烯是两种重要的激素,在植物的整个生命周期及其对非生物或生物胁迫的耐受性中发挥着至关重要的作用。近几十年来,越来越多的研究发现,这两种激素除了各自的作用外,更有可能通过相互作用发挥作用,形成一个复杂的调控网络。更重要的是,它们的功能会随着具体植物器官和发育阶段的不同而发生变化,相互作用也从协同到拮抗,这一点较少得到关注、比较和系统的总结。在这篇综述中,我们首先分别介绍了这两种植物激素的一般合成和作用信号通路,以及它们在正常和胁迫条件下与种子休眠和萌发、主根生长、嫩枝发育、果实成熟、叶片衰老和脱落、气孔运动调节等方面的相互作用。更好地了解 ABA 和乙烯之间复杂的相互作用,将增进我们对植物激素如何调控生长发育和应对胁迫的了解,并有助于将来通过组织特异性基因改造,培育出产量更高、对胁迫环境耐受力更强的作物。

Diverse functional interactions between ABA and ethylene in plant development and responses to stress.

Abscisic acid (ABA) and ethylene are two essential hormones that play crucial roles throughout the entire plant life cycle and in their tolerance to abiotic or biotic stress. In recent decades, increasing research has revealed that, in addition to their individual roles, these two hormones are more likely to function through their interactions, forming a complex regulatory network. More importantly, their functions change and their interactions vary from synergistic to antagonistic depending on the specific plant organ and development stage, which is less focused, compared and systematically summarized. In this review, we first introduce the general synthesis and action signaling pathways of these two plant hormones individually and their interactions in relation to seed dormancy and germination, primary root growth, shoot development, fruit ripening, leaf senescence and abscission, and stomatal movement regulation under both normal and stress conditions. A better understanding of the complex interactions between ABA and ethylene will enhance our knowledge of how plant hormones regulate development and respond to stress and may facilitate the development of crops with higher yields and greater tolerance to stressful environments through tissue-specific genetic modifications in the future.

期刊介绍: Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
