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 discuss about the organization of Ti Plasmid. Agrobacterium tumeifaciens harbours a large circular DNA known as Ti plasmid, which exists as an independent extra chromosomal entity of 200 kb size.
