Journal ArticleDOI
Drought stress enhances nutritional and bioactive compounds, phenolic acids and antioxidant capacity of Amaranthus leafy vegetable
TL;DR: Drought stress enhanced the quantitative and qualitative improvement of nutritional and bioactive compounds, phenolic acids, flavonoids and antioxidants of A. tricolor so that farmers of semi-arid and dry areas of the world could be able to grow amaranth as a substitute crop.
Journal ArticleDOI
Catalase, superoxide dismutase and ascorbate-glutathione cycle enzymes confer drought tolerance of Amaranthus tricolor.
TL;DR: It is clearly evident that CAT, ascorbate-glutathione cycle and SOD played a significant activity in ROS detoxification of tolerant A. tricolor variety.
Journal ArticleDOI
Drought Stress Effects on Growth, ROS Markers, Compatible Solutes, Phenolics, Flavonoids, and Antioxidant Activity in Amaranthus tricolor
Umakanta Sarker,Shinya Oba +1 more
TL;DR: The increased content of ascorbic acid indicated the crucial role of the ASC–GSH cycle for scavenging ROS in A. tricolor cultivar, and positive correlations among MDA, H2O2, compatible solutes, and non-enzymatic antioxidant suggested that compatible solute andnon-enzysmatic antioxidant played vital role in detoxifying of ROS in the cultivar.
Journal ArticleDOI
The Response of Salinity Stress-Induced A. tricolor to Growth, Anatomy, Physiology, Non-Enzymatic and Enzymatic Antioxidants.
Umakanta Sarker,Shinya Oba +1 more
TL;DR: The increase in SOD, ascorbate, and APX makes it predominantly evident that SOD and the AsA–GSH cycle had greatly contributed to quench reactive oxygen species (ROS) of the tolerant variety of A. tricolor.
Journal ArticleDOI
Augmentation of leaf color parameters, pigments, vitamins, phenolic acids, flavonoids and antioxidant activity in selected Amaranthus tricolor under salinity stress
Umakanta Sarker,Shinya Oba +1 more
TL;DR: In salt-stressed amaranth, correlation studies revealed strong antioxidant activity of leaf pigments, β-carotene, vitamin C, TPC, TFC, TAC, phenolic acids and flavonoids and antioxidants.
