Auxin plays a versatile role in regulating plant growth and development. The auxin efflux carrier PIN-FORMED (PIN) proteins dictate the distribution maximum of within various tissues. Despite extensive research on OsPINs recent years, their functions abiotic stress resistance, particularly cold tolerance, remain poorly understood. Here, we investigated OsPIN5b rice (Oryza sativa L.) development, as well its contribution to tolerance using overexpression technology. Overexpression (OE) resulted reduced shoot height lower number adventitious roots at seedling stage. Transgenic plants exhibited an earlier heading date, stunted growth, compromised agronomic traits, including shortened panicle length, decreased grain per panicle, seed size, setting rate during reproductive content transgenic lines was significantly elevated, indicated by upregulation auxin-responsive gene OsIAA20 increased levels quantified newly developed method. Compared with wild-type plants, OE markedly reduced, evidenced survival rates, higher electrolyte leakage, malondialdehyde (MDA) production following treatment. In line this, produced less soluble sugar proline, while accumulating more hydrogen peroxide (H2O2) superoxide anion radicals (O2-) after Furthermore, activities antioxidant enzymes, catalase (CAT), dismutase (SOD), peroxidase (POD), were notably upon treatment compared those WT plants. Additionally, OsRBOHH, which ROS production, upregulated both before chilling stress, suggesting that OsRBOHH potential production. Collectively, substantially disturbs homeostasis, resulting impaired architecture traits. More importantly, compromises perturbing homeostasis adversely influencing accumulation proline.

Abstract Zinc (Zn) is a vital micronutrient required for optimal plant growth and soil fertility. Its use in the form of nanoparticles (NPs) has gained significant attention agricultural applications. Green synthesized Zn‐based NPs offer an eco‐friendly solution to several conventional problems agriculture. Several plants, bacteria, fungi yeast have shown potential fabricating Zn that can provide environmentally friendly solutions agriculture approach aligned with sustainable practices, reducing dependency on harmful agrochemicals. act as promoters, enhance crop yield, promote resilience abiotic stressors are efficient protection agents. Their role smart delivery system, enabling targeted controlled release agrochemicals, further signifies their Because requires repeated applications hence, toxicological aspects cannot be ignored. reported cause phytotoxicity, including root damage, physiological biochemical disturbances, genotoxic effects. Furthermore, exposure poses risks microbiota, aquatic terrestrial organisms potentially impacting ecosystem. The green synthesis promising aspect advancing by agrochemical improving productivity. diverse protectants systems emphasize potential. However, essential ensure standardization doses safe effective use. Further research would help address such concerns developing viable modern © 2025 Society Chemical Industry.

Elevated salinity negatively impacts plant growth and yield, presenting substantial challenges to agricultural forestry productivity. The bHLH transcription factor family is vital for plants cope with various abiotic stresses. However, it remains uncertain whether factors can regulate salt stress in Populus ussuriensis. In the following study, a salt-induced PubHLH66 was identified from P. has typical conserved domain. Subcellular localization yeast two-hybrid (Y2H) assays confirmed that nucleus-localized transactivator activation region located at N-terminus. PubHLH66-OE PubHLH66-SRDX transgenic ussuriensis were obtained through Agrobacterium-mediated leaf disc transformation. Morphological physiological results demonstrated enhanced tolerance, as indicated by reduced electrolyte leakage (EL), malondialdehyde (MDA), H2O2 levels, along increased proline contents activities of peroxidase (POD) superoxide dismutase (SOD). contrast, PuHLH66-SRDX poplar showed decreased tolerance. Quantitative real-time PCR (RT-qPCR) tolerance regulating expression genes such PuSOD, PuPOD, PuP5CS, resulting reactive oxygen species (ROS) accumulation an improved osmotic potential. Thus, could be candidate gene molecular breeding enhance plants. These laid foundation exploring mechanisms ussuriensis, facilitating development more salt-tolerant trees combat increasing issue soil salinization globally.
