Comparative role of betalains and other key antioxidant metabolites in the photoprotection against acute exposure to UV-B radiation in Chenopodium quinoa and C. berlandieri seedlings

Chenopodium quinoa Willd. is a betalainic crop with remarkable tolerance to extreme environmental conditions. Despite numerous varieties grow at high altitudes, where UV-B radiation is intense, research on the effects of UV-B stress on this and related species is very scarce. In the present work we...
