was carried out with cDNA prepared from shoots of IR-64 (salt sensitive) andpokkali(salt tolerant) riceseedlings (14daysold) subjected to heat, osmotic, and salinity stress. Analysis of transcript abundance of OsCyp2 in shoot tissue of these two contrastingcultivarsofriceatseedlingstagerevealeditsdifferential stress-inducibleexpression(Fig.1a).Thisanalysisindicatedthat OsCyp2 is upregulated rapidly (after 30 min) under salinity stress in both IR-64 and Pokkali. However, the induction in Pokkali is much higher (7–8-fold) than IR-64. Similar observations were made when the transcript abundance for OsCyp2-P was analyzed in seedlings in response to high temperature or osmotic stress.
