Transcription profiling of Arabidopsis wild type and arrhythmic CCA1-34 line reveals that rhythmic growth is explained by coincidence between internal and external cues

ABSTRACT: Plant hypocotyls elongate in response to darkness. The response to darkness is gated by the circadian clock, such that wild-type plants (Col) only respond to darkness with growth once every 24 hours, whereas arrhythmic lines, such as CCA1-34, will respond to darkness with growth at any time of day. The experiment here was designed to find genes whose expression was correlated with growth. It should also pick up other genes that are gated by the circadian clock or that are direct targets of CCA1. Experiment Overall Design: Two genotypes were uses, wild-type (Col) and the arrhythmic CCA1-34 line that overexpresses the CCA1 protein. Plants were entrained in short day conditions for four days and then subjected light/dark pulses consisting of 160 minutes of light and 320 minutes of dark. W
