Comparative Analysis and Insilico Characterization of LEA, DREB and OsDHODH1 Genes Involved in Drought Resistance of Oryza Sativa

Paddy being the most stable food crop of South India, has been facing a high demand for supply. There are several stress conditions faced by the paddy cultivators which may include salinity, drought, floods, harsh climatic changes, etc. Withstanding these parameters are the potential property of the Paddy variant, which is attributed to its genetic makeup. Some of the genes responsible for making the plant stress tolerant include LEA, DREB, OsDHODH1 etc. and are considered for the current study. The work is an extension of our previous study on extraction of these genes and sequencing. The sequences of these genes are analyzed both structurally and functionally, so as to implement the crop improvement strategies, if required. The three genes are also subjected to the conservation study of their genetic and protein sequences. The results of the comparative studies revealed that the three genes do not share any sequence similarity or conservation among their genes and protein sequences is absent. The protein network study conducted, failed to detect any common legends or proteins being interacted in their metabolic pathways. This study can conclude that at the sequence level of these three genes do not share any similarity or conservation in spite of their functional similarity in stabilizing the plant under stress conditions.
