Although legumes are of primary economic importance for human and livestock consumption, the information regarding signalling networks during plant stress response in this group is very scarce. is a major experimental model within the Leguminosae family, whereas and are frequent components of natural and agricultural ecosystems worldwide. These species display differences in their perception and response to diverse stresses, even at the genotype level, whereby they have been used in many studies aimed at achieving a better understanding of the plant stress-response mechanisms. However, we are far from the identification of key components of their stress-response signalling network, a previous step for implementing transgenic and editing tools to develop legume stress-resilient genotypes, with higher crop yield and quality. In this review we scope a body of literature, highlighting what is currently known on the stress-regulated signalling elements so far reported in spp. Our work includes a comprehensive review of transcription factors chaperones, redox signals and proteins of unknown function. In addition, we revised strigolactones and genes regulating phytochelatins and hormone metabolism, due to their involvement as intermediates in several physiological signalling networks. This work was intended for a broad readership in the fields of physiology, metabolism, plant nutrition, genetics and signal transduction. Our results suggest that species provide a valuable information platform for the study of specific protein-protein (PPI) interactions, as a starting point to unravel signalling networks underlying plant acclimatation to bacterial and abiotic stressors in legumes. Furthermore, some species may be a source of genes whose regulation improves stress tolerance and growth when introduced ectopically in other plant species.
尽管豆类对人类和牲畜消费具有重要的经济意义，但关于该类植物在胁迫响应过程中信号网络的信息却非常匮乏。[物种名称1]是豆科植物中的主要实验模型，而[物种名称2]和[物种名称3]是全球自然和农业生态系统中的常见组成部分。这些物种在对各种胁迫的感知和响应上存在差异，即使在基因型水平也是如此，因此它们被用于许多旨在更好地理解植物胁迫响应机制的研究中。然而，我们距离识别其胁迫响应信号网络的关键组成部分仍有很大差距，而这是实施转基因和编辑工具以培育具有更高作物产量和品质的抗逆豆类基因型的前一步骤。在本综述中，我们梳理了大量文献，突出了目前在[物种名称]属中报道的胁迫调节信号元件的已知情况。我们的工作全面回顾了转录因子伴侣蛋白、氧化还原信号以及功能未知的蛋白质。此外，我们还对独脚金内酯以及调节植物螯合肽和激素代谢的基因进行了综述，因为它们作为中间体参与了多个生理信号网络。这项工作面向生理学、代谢、植物营养、遗传学和信号转导领域的广大读者。我们的结果表明，[物种名称]属物种为研究特定的蛋白质 - 蛋白质（PPI）相互作用提供了一个有价值的信息平台，作为解开豆类植物适应细菌和非生物胁迫背后信号网络的起点。此外，一些[物种名称]属物种可能是基因的来源，当这些基因异位导入其他植物物种时，其调控可提高胁迫耐受性和生长。
