Transcriptome profiling and expression analyses of genes critical to wheat adaptation to low temperature


ABSTRACT: Understanding the mechanism of low temperature (LT) adaptation is crucial to the development of cold-tolerant crops. To identify the genes involved in the development of LT tolerance in the crown of hexaploid wheat we examined the global changes in genes expression during cold-treatment using the Affymetrix Wheat Genome Chip. Time-series experiment with 4 genotypes x 8 time-points X 3 biological replicates in random block design; 96 hybridizations

To identify the genes involved in the development of low temperature (LT) tolerance in hexaploid wheat, we examined the global changes in expression in response to cold of the 55,052 potentially unique genes represented in the Affymetrix Wheat Genome microarray. We compared the expression of genes in winter-habit (winter Norstar and winter Manitou) and spring-habit (spring Manitou and spring Norstar)) cultivars, wherein the locus for the vernalization gene Vrn-A1 was swapped between the parental  ...[more]
