Clock genes and diurnal transcriptome dynamics in summer and winter in the gymnosperm Japanese cedar (Cryptomeria japonica (L.f.) D.Don).

ABSTRACT:

Background

The circadian clock and diurnal dynamics of the transcriptome are presumed to play important roles in the regulation of physiological, biological and developmental processes synchronized with diurnal and annual cycles of plant environments. However, little is known about the circadian clock and its regulation in gymnosperms, including conifers. Here we present the diurnal transcriptome dynamics of Japanese cedar (Cryptomeria japonica (L.f.) D.Don) in both active (summer) and dormant (winter) periods.

Results

Microarray analysis revealed significant differences in transcripts between summer and winter, and diurnal transcriptome dynamics only in the summer. About 7.7% of unique genes (556 out of 7,254) on the microarray were periodically expressed in summer. Express
