In this article we will discuss about the physiology of cold stress on plants. Plants produce number of proteins in response to cold and freezing temperature. More than 54 cold-inducible genes have been identified using cDNA microarray technology. In the process of various stress inducible gene expression, nearly 10% of the drought inducible genes are also induced by cold-stress indicating [...]
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 shock genes are prevalent in [...]
In this article we will discuss about the effect of salt stress on plants. Agricultural productivity is severely affected by high soil salinity and is responsible for decline in soil fertility throughout the world. It is estimated that more than 30 percent of irrigated soil in India has been affected by high soil salinity. Nearly 20 million hectares are being [...]
