(Submitter supplied) 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 regulons of each phytochrome under long day photoperiods.

(Submitter supplied) Two aspects of light are very important for plant development: the length of the light phase or photoperiod and the quality of incoming light. Photoperiod detection allows plants to anticipate the arrival of the next season, whereas light quality, mainly the red to far-red ratio (R:FR), is an early signal of competition by neighbouring plants. phyB represses flowering by antagonising CO at the transcriptional and post-translational levels. more...

(Submitter supplied) Daylength is a key indicator of seasonal information that determines major patterns of behavior in plants and animals. Photoperiodism has been described in plants for about 100 years, but the underlying molecular mechanisms of daylength perception and signal transduction in many systems are not well understood. In trees, photoperiod perception plays a major role in growth cessation during the autumn as well as activating the resumption of shoot growth in the spring, both processes controlled by FLOWERING LOCUS T2 (FT2) expression levels and critical for the survival of perennial plants over winter. more...

(Submitter supplied) Daylength is an important seasonal cue, and genetic variation in the regulation of photoperiodism has been selected for in adapting wheat and barley to northern latitudes. Despite the importance of this trait, the mechanism by which monocot plants sense photoperiod is not known. We find in Brachypodium distachyon that photoperiodism is mediated by phytochromeC (phyC), a chromophore that acts as a molecular timer and measures the length of the night. more...

(Submitter supplied) Phytochromes are red/far-red light photoreceptors. We sought to test at the transcriptomic level if Arabidopsis mutants lacking all phytochromes (from phyA to phyE), or just retaining trace levels of phyC, had transcriptional response to red light exposure.

(Submitter supplied) Purpose: The goals of this study are to compare the transcriptome profiling and alternative splicing (AS) profiling between Col-0 wild type and SFPS knockout mutant (sfps-2) through RNA-seq to determine the molecular mechanisms of how splicing factor SFPS regulates photomorphogenesis in Arabidopsis. Results: Using an optimized data analysis workflow, we mapped about 100 million sequence reads per sample to the Arabidopsis genome (TAIR10) and identified 1495 differentially expressed genes between Col-0 and mutant dark samples; 1361 differentially expressed genes between Col-0 and mutant red light treated samples; 4291 differentially expressed genes between Col-0 dark and red light treated samples; and 4479 differentially expressed genes between mutant dark and red light treated samples. more...

(Submitter supplied) The maintained vegetative phase (mvp) mutant has a non-flowering phenotype caused by deletions including, but not limited to, the genes CYS, PHYC and VRN1. However the impact of these deletions on flowering genes and global gene expression is still unknown. In this study, we showed that these deletions caused the up-regulation of several pathogenesis related (PR) and jasmonate responsive genes using microarray analysis. more...

Four-day-old dark-grown wild-type RLD and phyA101, phyB1 and phyAphyB mutant seedlings were transferred to Rc (680 nm, 8 mol m-2 s-1) for 1 h or retained in darkness as controls. Three different biological replicates of each treatment were grown separately and extracted, processed, and analyzed independently.RNA was extracted and subjected to expression analysis by using the Affymetrix ATH1 microarray containing approximately 22,000 Arabidopsis genes .

(Submitter supplied) 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 been well-known that microRNAs (miRNAs) perform important roles in plant development and stress responses. more...

(Submitter supplied) 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-dependent bilin reductases (FDBRs). There are two FDBRs in Physcomitrella patens, HY2 and PUBS. Knocking out both generates the phytochrome-deficient mutant. more...

(Submitter supplied) phytochrome B (phyB) acts as the red light photoreceptor and negatively regulates the growth-promoting factor PHYTOCHROME INTERACTING 4 (PIF4) through a direct physical interaction, which in turn changes the expression of a large number of genes. phyB-PIF4 module regulates a variety of biological and developmental processes in plants. In this study, we demonstrate that B-BOX PROTEIN 11 (BBX11) physically interacts with both phyB and PIF4. more...

And long-read sequencing for mixed whole grains from 14 and 25 DPA was employed to obtain full-length transcripts. A series of differentially expressed genes and tissues-specific genes of embryo and endosperm were identified. Moreover, 4351, 4641, 4516 and 4453 genes with A, B and D homoeoloci were detected in the four tissues. more...
