TranscriptomicsGenome-wide identification of microRNAs and their targets involved in the phyB-mediated light signaling pathway in rice
Phytochrome B (phyB), one member of phytochrome family in rice, plays important roles in regulating a range of developmental processes, and stress responses. However, little information about the mechanism involved in phyB-mediated light signaling pathway has been reported in rice. Another, it has b...

TranscriptomicsTranscription profiling of Arabidopsis dark-grown phyAphyB seedlings expressing the Y276H mutant of phyB (YHB) reveals a light-independent allele of phytochrome B faithfully recapitulates photomorphogenic transcriptional networks
Dominant gain-of-function alleles of Arabidopsis phytochrome B were recently shown to confer light-independent, constitutive photomorphogenic (cop) phenotypes to transgenic plants (Su & Lagarias 2007 Plant Cell 19, 2124-2139). In the present study, comparative transcript profiling experiments were p...

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...

TranscriptomicsRNA-seq studies using wheat PHYTOCHROME B and PHYTOCHROME C mutants reveal shared and specific functions in the regulation of flowering and shade-avoidance pathways
The phytochromes (PHYs) are a family of photoreceptors which absorb light of red and far-red wavelengths to modulate developmental responses in photosynthetic organisms. We developed knockout mutants of PHYB and PHYC in wheat and performed replicated RNA-seq studies to analyze and compare the regulo...

TranscriptomicsTemperature-controlled inhibition of phyB action
It has been established that the frequently reported early flowering phenotype of the phyB mutant is very sensitive to small changes in ambient temperature (Halliday et al., 2003). A 6oC drop in temperature to 16oC is sufficient to abolish the pronounced early flowering phyB phenotype observed at 22...

ProteomicsPHYB and PRR9 comprises a tandem thermosensitive switch in Arabidopsis
The ability of natural plants to withstand extremely high temperature is hampered by two main issues: temperature perception and adaptation. Circadian components involved in temperature compensation (TC) may help plants adjust to high temperature environments. Here, we report that PRR9 is evolved as...

TranscriptomicsAnalyses of phyB-regulated genes by RNA-seq
The phytochrome family consists of five numbers (phyA-phyE) in Arabidopsis, of which phyB is the best characterized and shown to play a major role in mediating red light inhibition of hypocotyl elongation. In order to reveal the molecular basis for phyB-mediated red light signaling to promote photom...
