The state of Jammu and Kashmir has been chosen for the implementation of the 'Aroma Mission' program, by the Indian Institute of Integrated Medicine (IIIM) in collaboration with the Department of Agriculture of the state, due to its peculiar climate, which is complimented by the presence of a growing market for the products of these plants, like aromatic oils.
(2008) mentioned that homozygous recessive allele of badh2 gene also induced the formation of 2AP and rice becomes aromatic. Thus, gene expression analysis of badh2 gene using reverse transcription quantitative PCR (RTqPCR) with relative quantification method could explore the genetic condition of aromatic rice as well as the influences of temperature on aroma gene by analyzing biochemical and physiological changes of aromatic rice due to the changes of badh2 gene expression level (Livak and Schmittgen, 2001; Kim et al., 2003).
