The Transcriptomic Regulation of Berry Development is More Important at Night than During the Day

ABSTRACT: In order to circumvent environmental changes throughout fruit development, young and ripening berries were sampled simultaneously on continuously flowering microvines acclimated to controlled circadian light and temperature changes. Gene expression profiles along fruit development were monitored during both day and night with whole genome microarray Nimbelgen® vitis 12x, yielding a total number of 9273 developmentally modulated probesets. All day-detected transcripts were modulated at night, whereas 1755 genes were night-specific. Very similar developmental patterns of gene expression were observed upon independent hierarchical clustering of day and night data, whereas functional categories of allocated transcripts varied according to time of the day. Many transcripts within pathways,
