Post-acclimation transcriptome adjustment is a major factor in freezing tolerance of winter wheat

Cold-acclimated winter wheat plants were slowly frozen to −10°C, and then the temperature was either maintained at −10°C or was lowered further to −12°C. Expression levels of a total of 423 genes were significantly altered in these treatments; genes upregulated outnumbered those downregulated by about a 9:1 ratio. Sixty-eight genes were upregulated at least… CONTINUE READING
