ABSTRACT Globally, the catastrophic climate change has emerged as a significant problem. Abiotic stress, such as drought, salt, light intensity and very low or high temperatures, inhibits or slows down various plant processes, which eventually results in reduced or aberrant plant development. Chilling stress can affect morpho-physiological, and molecular responses in crop plants as a result of extreme and abrupt global temperature changes. This stress has a negative impact on plant development and production owing to injury, biochemical and physiological disturbances and molecular alterations. In order to tolerate freezing stress, plants use a variety of common and unique physiological and molecular defensive strategies. In this review we outlined the most recent researches on plant’s reactions to chilling stress, as well as prospective management approaches for increasing plant resistance to chilling challenges.
