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 […]

Gene Expression Profiles in Response to Stress | Genetics
Article Shared by
In this article we will discuss about the gene expression profiles in response to stress. Microarray technology has been the useful tool for analyzing gene expression pattern in stressed plants. Full-length cDNA microarray analysis identified 44 drought-inducible genes. Fourteen of these genes were reported to be drought-inducible genes, such as rd 29A/cor 78, cor 15a, […]
Production of Osmo-Protective Compounds | Genetics
Article Shared by
In this article we will discuss about the production of osmo-protective compounds. Plants exhibit certain degree of defences against various environmental stresses by producing various osmoprotectants (Table 15.1). Accumulation of osmoprotectants and osmolytes like quarternary amines, amino acids and sugar alcohols increases their stress tolerance. Stress tolerant plants accumulating such compounds are more effective in […]
