Transcriptome Profiling of Wheat Genotypes Differing in Bread Baking Quality under Different Environments
Preliminary comparisons showed that the public Affymetrix array platform was more sensitive in detecting changes in gene expression in developing wheat grain than a cDNA array platform. Affymetrix arrays were therefore used to compare gene expression patterns in developing grain of seven doubled haploid lines (DHLs) from a cross between wheat cvs Spark ×Rialto, showing that over 440 genes were differentially expressed (significant at P <0.05). The seven DH lines also exhibited differences in processing properties and a number of the differentially expressed transcripts were associated with these.
