Abstract

Potassium (K or K⁺) is a vital macronutrient that influences numerous physiological processes related to plant physiology and development. Recently, there is a growing focus on enhancing K+-use efficiency (KUE) to ensure optimal plant growth, especially in K+ deficient soils. Most approaches are centred on targeting genes associated with K+ sensing, signalling and other pathways related to plant hormones. However, despite progress, the success stories for generating high KUE crops are still limited. In view of this, the present review highlights the role of hormonal signalling in regulating K+ deficiency-induced responses in plants. We integrate shreds of evidence of how these K+-hormone signalling crosstalk modulate root-system architecture, K⁺ uptake and stress resilience. Furthermore, a meta-analysis-based assessment of different hormones highlighted the central role of jasmonic acid and abscisic acid in mediating K⁺ deficiency-induced changes at the transcriptional level. The present review offers novel insights into K+-hormone crosstalk that can be used as a framework for advancing KUE research and addressing challenges towards global food security.

植物缺钾与激素信号传导。
钾(K或K +)是一种重要的常量营养素,影响着与植物生理和发育相关的许多生理过程。近年来,提高钾离子利用效率(KUE)以保证植物的最佳生长,特别是在缺钾土壤中受到越来越多的关注。大多数方法都集中在与K+感知、信号传导和其他与植物激素相关的途径相关的基因上。然而,尽管取得了进展,但培育高KUE作物的成功案例仍然有限。鉴于此,本文综述了激素信号在植物K+缺乏诱导反应中的作用。我们整合了一些证据,证明这些K+激素信号串扰如何调节根系结构、K+的吸收和应力恢复能力。此外,一项基于不同激素的荟萃分析评估强调了茉莉酸和脱落酸在介导K +缺乏诱导的转录水平变化中的核心作用。本综述为钾离子激素串扰提供了新的见解,可作为推进钾离子激素串扰研究和应对全球粮食安全挑战的框架。
