Abstract
A sustainable food system ensures food security and nourishment for future generations. Rice (Oryza sativa L.) requires emergence stress tolerance for successful cultivation in germination and early establishment stages. According to the FAO (Food and Agriculture Organization) study, rice is one of the most important worldwide cereal crops and a staple food for more than half of the world’s population. Over the past few years, drastic climatic changes have been subjected to many abiotic and biotic stresses. Global estimates express that a total of 1000 million hectares of cultivated land is affected by abiotic and biotic stress. Besides this around 30% of the irrigated land area is also disturbed. This review discusses the mechanisms of stress-tolerant variants and understanding the recent developments of complex tolerance phenomena. Here, we have compiled the logical pieces as evidence of successful applications of potent molecular tools for boosting stress tolerance in rice, their prospects and limitation. This information would help researchers better understand the genetic enhancement of stress tolerance in rice.
