Catalase, superoxide dismutase and ascorbate-glutathione cycle enzymes confer drought tolerance of Amaranthus tricolor [PDF]
Scientific Reports, 2018 AbstractThe study was performed to explore physiological, non-enzymatic and enzymatic detoxification pathways of reactive oxygen species (ROS) in tolerance ofAmaranthus tricolorunder drought stress. The tolerant genotype VA13 exhibited lower reduction in growth, photosynthetic pigments, relative water content (RWC) and negligible increment in ...

Ascorbate-glutathione cycle confers salt tolerance in Egyptian lentil cultivars. [PDF]
Physiol Mol Biol Plants, 2018 In order to investigate the salt tolerance mechanism in Egyptian lentils, five cultivars were grown under different salinity levels. The results indicated that Giza 9 is salt-tolerant, while Giza 4 is a salt-sensitive lentil cultivar, as Giza 9 showed the highest germination percentage and relative water content, the lowest decline in root and shoot ...
