In this study, effects mechanisms exogenous SA-triggered adaptation were investigated by detecting physiological biochemical indexes expression tolerance genes. The results showed that application could significantly increase antioxidant enzyme activities seedlings under stress, thereby reducing contents H2O2 MDA maintaining growth seedlings. Moreover, genes abiotic such as OsDREB2A, OsSAPK8, OsSAPK10 OsMYB2, up-regulated treatment, further enhance those like OsDREB2A suggesting might regulate activity via inducing enhancing rice. will enrich knowledge provide a reference for studying mechanism resistance rice, breeding new germplasm with improved resistance.

Drought stress severely damages wheat growth and photosynthesis, plants at the grain-filling stage are most sensitive to drought throughout entire period of development. Exogenous spraying sodium nitroprusside (SNP) can alleviate damage caused by stress, but mechanism regulating proline pathway remains unknown. Two cultivars, drought-sensitive Zhoumai 18 drought-tolerant Zhengmai 1860, were used as materials when cultivated stage. The results show that under SNP pretreatment effectively improved physiological basis photosynthesis water use efficiency two increased their tolerance photosystem II (PSII) damage, maintained a normal photosynthetic rate yield. induced an increase in pyrroline-5-carboxylate synthase (TaP5CS) gene transcription, comparatively greater was detected 1860. When treatment applied before exposure, TaP5CS transcription further enhanced. Induction promoted accumulation response osmotic ability, net rate, thereby increasing dry matter yield traits. In this study, exogenous regulates genes related metabolism provides theoretical for establishment cultivation technology using resist stress.

Due to extended periods of below-normal rainfall and rising temperatures, drought is a significant global issue for agricultural productivity. Hydrological, agricultural, meteorological droughts all pose different problems with regard the availability water important crops, which in turn impacts plant development yield. Depending on crop species stage maturity, stress degrades metabolism physiological processes, resulting decreased growth yield losses that can range from 30% 90%. Acclimatization adaptation are two basic techniques plants use survive drought. Rapid alterations processes chemical composition, including modifications osmotic pressure, root leaf size, antioxidant systems, part acclimatization. Xerophytism succulence characteristics drought-resistant have evolved assist preserve cellular integrity balance water-limited environments. Even these tactics, majority crops—such as maize, rice, wheat—remain extremely vulnerable stress. To lessen effects drought, researchers looked into number strategies, both conventional cutting-edge methods. Conventional techniques, like application growth-promoting bacteria (PGPB) morphological modifications, remain essential improving resilience. Recent breakthroughs provided innovative alternatives such nanoparticle (NP) treatments biochar, enhance Biochar enhances soil moisture retention nutrient accessibility, whereas nanoparticles augment absorption bolster molecular resilience under Furthermore, microbial inoculants absorption, facilitating arid conditions. This review examines three staple emphasizing traditional novel approaches consequences We highlight how combining insights ecology, biochemistry, biology, technologies biochar boost production resistance water-scarce

Rice (Oryza sativa L.), an important food crop, necessitates more water to complete its life cycle than other crops. Therefore, there is a serious risk rice output due water-related stress. Drought stress results in morphological changes, including the inhibition of seed germination, reduced seeding growth, leaf area index, flag area, increased rolling, as well decrement yield traits, such plant height, biomass, number tillers, and 1000-grain yield. Stress also causes formation reactive oxygen species (ROS) O2−, H2O2, OH−, which promote oxidative plants cause damage. The process degradation owing produces cell damage reduction nutrient intake, photosynthetic rate, RWC, WUE, stomatal closure, may be responsible for transpiration rate dry matter under decreasing soil moisture. Plants have ability produce antioxidant that can either enzymatic (SOD, POD, CAT, GPX, APX) or non-enzymatic (AsA, GSH) nature overcome During drought, several biochemical osmoprotectants, like proline, polyamines, sugars, accumulated, enhance drought tolerance rice. To meet demands ever-growing population with diminishing resources, it necessary crop varieties are highly adapted environments, involve adopting some mitigation strategies.

Rice is an important food crop, while it severely affected by drought stress. Viewing this point in mind we conducted experiment to see the physiological responses and yield potential of selected rice genotypes under inadequate moisture condition. Two soil condition: one sufficient condition (control; 95-100% field capacity (FC)) another deficit (moisture stress; 40-45% FC) with five replications was maintained. Six tolerant susceptible genotype standard check variety were used. Results revealed that BU Acc 37 32 showed highest RWC, WRC, rate photosynthesis, conductance stomata, transpiration rate, total chlorophyll content, proline soluble sugar 5 lowest value those parameters during water stress In contrast, WSD, WUC, accumulation H2O2 malondialdehyde noticed 32, whereas Tolerant also higher antioxidant enzyme activity than 5.
