Physiological and biochemical responses of wheat to viruses and climate change.

We identified the presence of Wheat streak mosaic virus, Barley yellow dwarf virus and Wheat dwarf virus, all of which have a significant epidemic potential, leading to reduced crop yields and compromised quality. Additionally, we observed "cold peaks" due to a temperature drop of more than 18ºC, leading to stress symptoms such as leaf reddening and the development of chlorotic and yellowishbrown stripes. It was studied the wheat physiological-biochemical responses to viruses of several varieties according to parameters of ROS homeostasis, chlorophyll and saccharide levels and the activity of protective proteins.enwheatvirusesplant biochemical protective responsesArticlehttps://doi.org/10.53040/gppb8.2024.27
