TranscriptomicsSigma2 and Sigma6-mediated plastid retrograde signals control nuclear gene expression in Arabidopsis
Retrograde signaling from the chloroplast to the nucleus is necessary to regulate the chloroplast proteome during development and fluctuating environmental conditions. Although the specific chloroplast process(es) that must occur and the nature of the signal(s) that exits the chloroplast are not wel...

TranscriptomicsTranscription profiling of Arabidopsis sav mutants
Plants grown at high densities perceive a decrease in the red to far-red (R:FR) ratio of incoming light, resulting from absorption of red light by canopy leaves and reflection of far-red light from neighboring plants. These changes in light quality trigger a series of responses known collectively as...

TranscriptomicsTranscription profiling of Arabidopsis dark grown photoreceptor mutants seedlings
Phytochromes mediate a profound developmental shift when dark-grown seedlings are exposed to light. Here we show that a subset of genes is up regulated in phytochrome B (phyB) mutants even before dark-grown seedlings are exposed to light. Most of these genes bear the RY cis motif, which is a binding...

TranscriptomicsTranscription profiling of Arabidopsis phyA and phyB mutants, and wild type plants, grown in the dark
Phytochromes mediate a profound developmental shift when dark-grown seedlings are exposed to light. Here we show that a subset of genes is up regulated in phytochrome B (phyB) mutants even before dark-grown seedlings are exposed to light. Most of these genes bear the RY cis motif, which is a binding...
