TranscriptomicsArabidopsis phytochrome A directly targets numerous promoters for individualized modulation of genes in wide range of pathways [RNA-seq]
The far-red light (FR) photoreceptor phytochrome A (phyA) contains no DNA binding domain but associates with CHS promoter through its chaperon FHY1 and transcription factors to regulate transcription. Here, we performed a genome-wide identification of phyA targets using a combination of phyA ChIP- a...

ProteomicsPhytochrome B photobodies are comprised of phytochrome B and its primary and secondary interacting proteins
Phytochrome B (phyB) is a plant photoreceptor that forms a membraneless organelle called a photobody. However, its constituents are not fully known. Here, we isolated phyB photobodies from Arabidopsis leaves using fluorescence-activated particle sorting and analyzed their components. We found that a...

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...

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...

TranscriptomicsTranscription profiling of Arabidopsis thaliana phytochrome interacting factors 4 and 5 redundantly limit seedling de-etiolation in continuous far-red light.
Phytochromes are red/far red photosensors regulating numerous developmental programs in plants. Among them phytochrome A (phyA) is essential to enable seedling de-etiolation in continuous far-red (FR) light a condition mimicking the environment under a dense canopy. The ecological relevance of this ...

TranscriptomicsmRNA-seq of Physcomitrella protonema responding to 1 hr red light in wild type and the phytochrome-deficient mutant
The red/far-red light photoreceptor phytochrome mediates photomorphological responses in plants. For light sensing and signaling, phytochromes need to associate with open-chain tetrapyrrole molecules as the chromophore. Biosynthesis of tetrapyrrole chromophores requires members of ferredoxin-depende...

TranscriptomicsBrassinosteroid, gibberellin, and phytochrome impinge on a common transcription module in Arabidopsis
Brassinosteroid (BR) and gibberellin (GA) promote many similar developmental responses in plants; but their relationship remains unclear. Here we show that BR and GA act interdependently through a direct interaction between the BR-activated BZR1 and GAinactivated DELLA transcription regulators. GA p...
