High resolution diel transcriptomes of autotetraploid potato reveal expression and sequence conservation among rhythmic genes.

ABSTRACT:

Background

Photoperiodic changes in diel cycles of gene expression are pervasive in plants. The timing of circadian regulators, together with light signals, regulate multiple photoperiod-dependent responses such as growth, flowering or tuber formation. However, for most genes, the importance of cyclic mRNA levels is less clear. We analyzed the diel transcriptome of modern cultivated potato, a highly heterozygous autotetraploid. Clonal propagation and limited meiosis have led to the accumulation of deleterious alleles, making tetraploid potato an ideal model system to investigate the conservation of cyclic expression and cyclic genes during artificial selection and clonal propagation.

Results

Our results indicate that rhythmic alleles of cultivated potato are more highly expr
