10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 4 2011 (October - December) Quantitative real-time PCR (RT-PCR) has already been used to study the expression profile of several plant gene families. This study demonstrates the potential of RT-PCR to measure the expression of heat shock protein (HSP) genes in groundnut ( lessThan i greaterThan Arachis hypogaea lessThan /i greaterThan L.) that underwent salt stress followed by RT-PCR of lessThan i greaterThan hsp70 lessThan /i greaterThan mRNA using the housekeeping gene tubulin ( lessThan i greaterThan tub lessThan /i greaterThan ) as a reference gene and the fluorogenic dye SYBR Green I. Expression of HSP70 gene was identified in salt stressed groundnut genotype TMV7. Indhuleka.A And Jeyanthi,G.P.
