Modulation of Antioxidant Defense System Is Associated with Combined Drought and Heat Stress Tolerance in Citrus
Drought and high temperatures are two major abiotic stress factors that often occur simultaneously in nature, affecting negatively crop performance and yield. Moreover, these environmental challenges induce oxidative stress in plants through the production of reactive oxygen species (ROS). Carrizo citrange and Cleopatra mandarin are two citrus genotypes with contrasting ability to cope with the...
متن کاملDifferential Responses of Polyamines and Antioxidants to Drought in a Centipedegrass Mutant in Comparison to Its Wild Type Plants
Centipedegrass (Eremochloa ophiuroides [Munro] Hack.) is an important warm-season turfgrass species with low turf maintenance requirements. However, our knowledge on physiological adaptation of centipedegrass to drought stress is limited. Physiological responses to drought in a gamma-ray-induced mutant 22-1 as compared with two wild type (WT) lines were analyzed for understanding of drought tol...
متن کاملGeriforte stimulates antioxidant defense system.
Geriforte, a herbomineral preparation, feeding at 1 g% dose level for 4 weeks significantly increased catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in liver of mice. In rats, in addition to these enzymes, the levels of reduced glutathione (GSH) were also significantly enhanced. However, only SOD in mice and, CAT and SOD activities in rat lung were signif...
متن کاملEarly Cold-Induced Peroxidases and Aquaporins Are Associated With High Cold Tolerance in Dajiao (Musa spp. ‘Dajiao’)
Banana is an important tropical fruit with high economic value. One of the main cultivars ('Cavendish') is susceptible to low temperatures, while another closely related specie ('Dajiao') has considerably higher cold tolerance. We previously reported that some membrane proteins appear to be involved in the cold tolerance of Dajiao bananas via an antioxidation mechanism. To investigate the early...
متن کاملEvaluation of salinity response through the antioxidant defense system and osmolyte accumulation in a mutant rice
In order to assess the responses of Hashemi rice genotype and its advanced mutant line under salinity stress of 100 mM Sodium chloride (NaCl) for three and six days the shoot samples were taken for biochemical analysis. This experiment was performed in split plot based on randomized complete block design with three replications. The main factor was factorial combination of saline treatmen...
