Transcription profiling of wheat variety Chinese Spring and two derived chromosome 5A substitution lines treated with cold stress

ABSTRACT: Chromosome 5A of wheat is a major regulator of freezing tolerance. It harbours gene loci controlling freezing tolerance (Fr-A1 and Fr-A2) and vernalization requirement (Vrn-A1). The number of cold-responsive genes and their functional classification was studied by cDNA macroarray-based transcript profiling in the moderately freezing-sensitive wheat (Triticum aestivum L.) variety Chinese Spring and two derived chromosome 5A substitution lines exhibiting lower or higher levels of freezing tolerance, respectively. During 21-days of cold acclimation at 2 °C the transcript level changed significantly for 681 (6.6%) out of 10,297 studied unigenes. The freezing-tolerant substitution line exhibited about 1.5-fold higher number of differentially expressed genes compared to the sensitive one. Transc
