Validation of selected housekeeping genes under drought stress conditions.

<p>Expression profiling of candidate gene responsible for universal stress protein A-like (<i>uspA</i>) protein in drought imposed tissues (root, stem and leaves). The expression value of candidate gene was normalized with stable, combination of stable and least stable genes namely (i) <i>IF4α</i> (ii) <i>TUB6</i> (iii) <i>HSP90</i> (iv) <i>IF4α + TUB6</i> (v) <i>IF4α + HSP90</i> (vi) <i>IF4α + TUB6+HSP90</i> (vii) <i>ACT1</i> and (viii) <i>18SrRNA</i>. The relative quantitative values of selected drought responsive candidate gene were obtained after scaling to control samples. EDR: vegetative root stressed; LDR: reproductive root stressed; EDS: vegetative stem stressed; LDS: reproductive stem stressed; EDL: vegetative leaves stressed; LDL: reproductive leaves stressed.
