摘要

植物在其生命周期中会受到多种不利的环境影响。其中干旱胁迫是对农业生产力的主要威胁之一。为了在这种不稳定的环境中生存，植物已经发展出了一种机制，通过这种机制，它们可以根据传入的环境刺激来识别压力的严重性。为了对抗干旱的有害影响，植物使用各种策略来调节它们的生理激素特性。它们可以受到遮荫和微生物的调节，这一过程可以增强耐旱性并减少产量损失。植物激素，如脱落酸、生长素和乙烯，通过对各种代谢途径的影响，在与遮荫和微生物相关的抗旱性提高中发挥着重要作用。在这个过程中，CLAVATA3/胚胎周围区域相关的25肽由于其对ABA合成的影响而发挥主要作用，如我们的调控模型所示。

Shade and microbes enhance drought stress tolerance in plants by inducing phytohormones at molecular levels: A review

Plants are exposed to several adverse environmental effects during their life span. Among them drought stress is one of the major threats to agricultural productivity. In order to survive in such unstable environment, plants have developed mechanisms through which they recognize the severity of the stress based on the incoming environmental stimuli. To combat the detrimental effects of drought, the plants use various strategies to modulate their physio-hormonal attributes. They can be modulated by shade and microbes, which process can enhances drought tolerance and reduce yield loss. Plant hormones, such as abscisic acid, auxin and ethylene have a major role in the shade- and microbe-associated improvement of drought tolerance through their effects on various metabolic pathways. In this process, the CLAVATA3/EMBRYOSURROUNDING REGION-RELATED 25 peptide has a major role due to its effect on ABA synthesis as shown in our regulatory model.

期刊介绍： Journal of Plant Ecology (JPE) serves as an important medium for ecologists to present research findings and discuss challenging issues in the broad field of plants and their interactions with biotic and abiotic environment. The JPE will cover all aspects of plant ecology, including plant ecophysiology, population ecology, community ecology, ecosystem ecology and landscape ecology as well as conservation ecology, evolutionary ecology, and theoretical ecology.
