Abstract Due to global climate change, crops are certainly confronted with a lot of abiotic and biotic stress factors during their growth that cause serious threat development overall productivity. Among different stresses, salt drought considered the most devastating stressors impact on crop’s yield stability. Here, current study aimed elucidate how melatonin works in regulating plant biomass, oxidative stress, antioxidant defense system, as well expression genes related rice plants. Eight groups plants (3 replicates, 5 each) underwent varied treatments: control, melatonin, salt, drought, + melatonin. Melatonin (100 µM) was alternately applied week before exposure; received 100 mM NaCl every 3 days for weeks, involved 10% PEG. Young leaves were randomly sampled from each group. The results showed treatment markedly reduces damage by promoting root, shoot length, fresh dry weight, increasing chlorophyll contents, inhibiting excessive production markers. Salt significantly decreased water balance, damaged cell membrane reducing relative contents electrolyte leakage. However, treated high low Under conditions, exogenous application boosted level responsive like OsSOS , OsNHX OsHSF OsDREB Taken together, our reveal increases tolerance plants, suppressing ROS accumulation, elevating antioxidants efficiency, up-regulating genes.

Improvement of salinity tolerance in rice can minimize the stress-induced yield losses. Rice (Oryza sativa) is one Asia's most widely consumed crops, native to subtropical regions, and generally associated with sensitivity stress episodes. Salt-tolerant genotypes have been developed using conventional breeding methods; however, success ratio limited because complex nature trait high cost development. The narrow genetic base methods. Hence, it critical launch molecular tools for screening novel germplasm salt-tolerant genes. In this regard, latest techniques like quantitative loci (QTL) mapping, engineering (GE), transcription factors (TFs) analysis, clustered regularly interspaced short palindromic repeats (CRISPR) are reliable incorporating salt at level. Large-scale use these potent approaches leads identifying editing several genes/alleles, QTL/genes accountable holding mechanism rice. Continuous practices resulted a huge decline diversity, which great worry global food security. However, only way conserve diversity by exploring wild desired genes programs. review, we compiled logical evidences successful applications boosting rice, their limitations, future prospects.
