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 discus about the strategies for stress-tolerant plant. Several microorganisms have been used as a model system to characterize stress inÂduced genes. It is because they are equipped with wide array of stress relieving genes. Recently, attention has been focused towards higher plants in search of stress tolerance genes and sucÂcessful attempt to introduce these genes [...]
In this article we will discuss about the CIS-Acting elements and regulatory role of Dreb-Transcription factors. The promoter region of almost all stress inducible genes contains two major cis-acting elements. One of the most well characterized stress responsive genes, rd 29A (responsive to dehydration) of Arabidopsis contains two kinds of cis-acting elements in their promoter region. One is the ABA-responsive [...]
