Functional analysis of photo-oxidative stress responsive genes in wheat(Triticum aestivum L.) may benefit wheat improvement for high radiation use efficiency. A Chinese variety Xiaoyan 54 developed from distant hybridization between common wheat(T. aestivum, 2n=42) and tall wheatgrass(Thinopyrum ponticum, 2n=70) shows significant tolerance to high light induced photo-oxidative stress. Based on previous transcriptome analysis of Xiaoyan 54 in response to high light stress, six genes were selected in this stu...
