Physiology Iwuala, Emmanuel [1]. Differential responses in Pennisetum glaucum (L) and Zea mays (L) cultivars under simulated drought stress condition. Drought stress reduces plant growth and productivity. Two cultivars of Pennisetum glaucum (IP14599) and Zea mays (DTSYN11) were screened under simulated drought stress condition for 5 and 10 days. The effect of the drought stress was estimated by measuring biomass, relative water contents (RWC), water use efficiency (WUE), accumulation of malondialdehyde (MDA), catalase (CAT), ascorbate peroxidase (APX) and the expression levels of CBF gene were used as proxy for drought tolerance.IP14599 maintained high biomass production, RWC, WUE better than DTSYN11 after imposing drought stress.Expression of CBF gene in leaves and roots of IP14599 indicates high responsiveness to drought as compared to DTSYN11, where it support greater water transport. The low concentration of MDA and high accumulation of antioxidant enzymes as drought stress progresses suggest that IP14599 possess a certain measure of osmotic protection and induced ativity of antioxidant than in DTSYN11 thereby safeguarding death of plant. Thus, IP14599 cultivar indicated better survival mechanism in modulating mRNA expression as compared to DTSYN11 under drought stress. Log in to add this item to your schedule
