In this article we will discuss about the effect of freezing temperature tolerance on plants. Manifestation of cold acclamation is accomplished by increased freezing tolerance in several plants. Non-acclimatized plants are injured or killed by temperature above -10°C. Interestingly, certain freezing acclimated tree species can survive freezing temperature between -40 and -50°C, for example, non-acclimated […]

In this article we will discuss about the stress tolerance by antioxidants production. Abiotic stress including salt, chill and drought in plants induces production of reactive oxygen species (ROS), including superoxide radicals (O2–), hydrogen peroxide (H2O2) and hydroxyl radicals (OH). ROS production in cell is due to altered metabolic functions of cell organelles like chloroplast […]

In this article we will discuss about the effect of heat stress on plants. Elevation in the temperature of surrounding environment imposes heat stress on wide range of organisms. Heat stress is responsible for the induction of several heat inducible genes, commonly referred as heat shock genes, which encodes heat shock proteins. Expressions of heat […]
