With ever-increasing population, food security is a great concern nowadays. To assure food security, boosting up food production is very urgent. But due to global climate change, food security is under threat. As plants have no chance to move from their habitat, so they face environmental/abiotic stress. These include drought, waterlogging, salinity, temperature extremes (high and low), ozone, metal/metalloid toxicity, and other organic or inorganic pollutants. These stresses hamper plant growth, create stomata closure, reduce photosynthesis, alter respiration and transpiration, accumulate toxic molecules, disturb reproduction and finally decrease yield. Abiotic stresses are responsible for remarkable yield loss. All abiotic stresses are responsible for oxidative damage in plants and plants can minimize this damage through an antioxidant defense mechanism. To mitigate these effects of stress, various types of approaches towards stress tolerance have been studied and developed by plant biologists. It is very important to study plant stress physiology and the mechanism of survival under stress conditions to develop stress tolerance varieties through genetic/molecular tools. There is a thirst for further study to reveal the mechanism of plant survival and develop a new strategy to make the plant more adaptive under stress conditions. In the last few decades, a lot of progress has been made in understanding plant abiotic stress responses. This special issue will host such progress. Both research and review articles are welcome.
