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 [...]
In this article we will discuss about the plant responses to drought stress. With the exception of flooding, the major drought stresses result in water-deficit stress. The stressed plants exhibit striking responses by producing plant hormone abscisic acid (ABA), which plays an important role in tolerance against drought. Abscisic acid can induce the expression of stress relieving genes. More than [...]
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 Science (JIRCAS) identified 12 stress-inducible [...]
