Background: Mirabilis himalaica, distributed in the high-altitude, arid, and semi-arid regions of Xizang, exhibits great tolerance to drought, which is rich rotenoids other secondary metabolites. It still unknown, though, how drought stress influences rotenoid synthesis M. himalaica. Methods: In this study, calli himalaica were subjected 5% PEG6000 for 0, 20, 40 h divided into control group (CK), mild-drought-treated (M), high-drought-treated (H), respectively. We then analyzed relative content three main using high-performance liquid chromatography–electrospray ionization–tandem mass spectrometry (HPLC-ESI-MS/MS). Results: Our findings demonstrated that was significantly reduced under stress. Transcriptome analysis subsequently revealed 14,525 differentially expressed genes (DEGs) between different treatments. Furthermore, these DEGs exhibited enrichment pathways associated with isoflavone biosynthesis hormone signaling pathways. Key decreased expression patterns during also found be involved accumulation drought-responsive phytohormone signaling, including abscisic acid (ABA), auxin (IAA), jasmonic (JA). Conclusions: These elucidate molecular processes resistance shed light on relationship production

Plants must effectively respond to various environmental stimuli achieve optimal growth. This is especially relevant in the context of climate change, where drought emerges as a major factor globally impacting crops and limiting overall yield potential. Throughout evolution, plants have developed adaptative strategies for stimuli, with plant hormones reactive oxygen species (ROS) playing essential roles their development. Hormonal signaling maintenance ROS homeostasis are interconnected, indispensable growth, development, stress responses orchestrating diverse molecular during adversities. Nine principal classes phytohormones been categorized: auxins, brassinosteroids, cytokinins, gibberellins primarily oversee developmental growth regulation, while abscisic acid, ethylene, jasmonic salicylic strigolactones main orchestrators responses. Coordination between transcriptional regulation crucial effective responses, stress. Understanding interplay pivotal elucidating mechanisms involved review provides an overview intricate relationship ROS, redox metabolism, nine different plants, shedding light on potential enhancing tolerance sustainable crop production.

Abstract Salinity stress severely affects rice growth and reduces its productivity. With No Lysine Kinases (WNKs) are serine/threonine kinases emerging as potential candidate genes due to their involvement in various abiotic tolerance responses. However, studies providing mechanistic insights into the roles of WNKs plants remain scarce. In present study, OsWNK9‐ overexpressing lines showed strong salinity stress. Overexpression OsWNK9 also triggered accumulation abscisic acid (ABA) restored indole‐3‐acetic (IAA) concentrations roots, triggering stomatal closure shoots maintaining cell expansion root epidermal cells when challenged with salt treatment. The overexpression increased activity antioxidant enzymes, which further mitigated ROS‐mediated cellular damage under We identified that interacts Receptor for Activated Kinase C1A (RACK1A), ABA‐8′‐hydroxylase, (Vacuolar Type ATPase) V‐Type ATPase.
