Silicon (Si) has been shown to increase plant stress tolerance. However, the molecular mechanisms underlying the effects of Si in alleviating drought stress in winter wheat are unknown. The aim of this study was to investigate the effects of Si on photosynthetic pigments, antioxidant contents, and transcription of several genes involved in the antioxidant(More)
Polyphenols in whole grain wheat have potential health benefits, but little is known about the expression patterns of phenolic acid biosynthesis genes and the accumulation of phenolic acid compounds in different-colored wheat grains. We found that purple wheat varieties had the highest total phenolic content (TPC) and antioxidant activity. Among phenolic(More)
