Shared and genetically distinct Zea mays transcriptome responses to ongoing and past low temperature exposure.

ABSTRACT:

Background

Cold temperatures and their alleviation affect many plant traits including the abundance of protein coding gene transcripts. Transcript level changes that occur in response to cold temperatures and their alleviation are shared or vary across genotypes. In this study we identify individual transcripts and groups of functionally related transcripts that consistently respond to cold and its alleviation. Genes that respond differently to temperature changes across genotypes may have limited functional importance. We investigate if these genes share functions, and if their genotype-specific gene expression levels change in magnitude or rank across temperatures.

Results

We estimate transcript abundances from over 22,000 genes in two unrelated Zea mays inbred lines durin
