Rice, as a major staple crop, employs multiple strategies to enhance drought tolerance and subsequently increase yield. Osmotin-like proteins have been shown promote plant resistance biotic abiotic stress. However, the mechanism of osmotin-like in rice remains unclear. This study identified novel protein, OsOLP1, that conforms structure characteristics osmotin family is induced by NaCl CRISPR/Cas9-mediated gene editing overexpression lines were used investigate impact OsOLP1 on rice. Compared wild-type plants, transgenic plants overexpressing showed high with leaf water content up 65%, survival rate 53.1% regulating 96% stomatal closure more than 2.5-fold proline promotion through accumulation 1.5-fold endogenous ABA, enhancing about 50% lignin synthesis. knockout severely reduced ABA content, decreased deposition, weakened tolerance. In conclusion, finding confirmed drought-stress modulation relies accumulation, regulation, proline, accumulation. These results provide new insights into our perspective

Abstract Salinity has become a major environmental concern for agricultural lands, leading to decreased crop yields. Hence, plant biology experts aim genetically improve barley’s adaptation salinity stress by deeply studying the effects of salt and responses barley this stress. In context, our study aims explore variation in physiological biochemical five Tunisian spring genotypes during heading phase. Two treatments were induced using 100 mM NaCl (T1) 250 (T2) irrigation water. Significant phenotypic variations detected among response Plants exposed showed an important decline all studied parameters namely, gas exchange, ions concentration relative water content RWC. The observed decreases concentrations ranged from, approximately, 6.64% 40.76% K + , 5.91% 43.67% Na 14.12% 52.38% Ca 2+ 15.22% 38.48% Mg across different levels. However, under conditions, proline soluble sugars increased with average increase 1.6 times 1.4 concentration. Furthermore, MDA levels rose also genotypes, biggest rise Lemsi genotype (114.27% compared control). Ardhaoui Rihane higher photosynthetic activity other treatments. stepwise regression approach identified potassium content, /Na ratio, stomatal conductance SPAD measurement as predominant traits thousand kernel weight (R2 = 84.06), suggesting their significant role alleviating barley. Overall, at stage, accumulation irrigated soils saline significantly influences growth influencing exchange parameters, mineral composition genotype-dependent manner. These results will serve on elucidating genetic mechanisms underlying these facilitate targeted improvements barley's tolerance
