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 […]
