In this article we will discuss about the transgenic strategy of stress in plants. In Arabidopsis, overexpression of cDNA encoding DREB1 and DREB2 triggered expression of many stress tolerance genes under normal growing conditions. Thus, transgenic strategy resulted in increased tolerance to drought, salinity and cold stress. Researchers from Japan International Research Center for Agricultural […]
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 […]
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 […]
