Series GSE30711 Query DataSets for GSE30711

Title ChIP-Seq data from Arabidopsis thaliana under dark and far-red light
Organism Arabidopsis thaliana
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary FAR-RED ELONGATED HYPOCOTYL 3 (FHY3) and its homolog FAR-RED IMPAIRED RESPONSE 1 (FAR1) are two transposase-derived transcription factors initially identified as the key components in phytochrome A signaling and recently shown to function in the circadian clock. However, whether FHY3 and FAR1 are involved in other processes of plant development remains largely unknown. Here, we explored chromatin immunoprecipitation-based sequencing (ChIP-seq) analysis to identify 1745 and 1171 FHY3 direct binding target genes in darkness and far-red light conditions, respectively in the Arabidopsis thaliana genome. This analysis revealed that FHY3 preferentially binds to the gene promoters through the previously identified typical FHY3/FAR1 binding motif. Interestingly, FHY3 also binds to two novel motifs in the 178-bp repeats of the Arabidopsis centromere regions in vivo. Comparison between the ChIP-seq and microarray data indicates that FHY3 regulates the expression of 196 and 85 genes in dark and far-red respectively by directly binding to their promoters. FHY3 also co-regulates a number of common target genes with PHYTOCHROME INTERACTING FACTOR 3-LIKE 5 (PIL5) and ELONGATED HYPOCOTYL 5 (HY5). Moreover, our genome-wide identification of FHY3 direct target genes ultimately led to the discovery and validation of a new role of FHY3 in controlling chloroplast development, by directly activating the expression of ACCUMULATION AND REPLICATION OF CHLOROPLASTS5 (ARC5), a key gene regulating chloroplast constriction and division. Taken together, our data suggest that FHY3 is involved in regulating multiple facets of plant development, thus providing new insights into the functions of this type of transposase-derived transcription factors.
 
Overall design To determine the global in vivo binding sites of FHY3, we performed ChIP-seq analysis using 35S:3FLAG-FHY3-3HA fhy3-4 transgenic lines in which the 3FLAG-FHY3-3HA fusion proteins could largely rescue the long hypocotyl phenotype of the fhy3-4 mutants The seedlings were grown in D or continuous FR light conditions for 4 days, and then chromatin fragments were prepared using the commercially monoclonal anti-FLAG antibodies. We then generated two DNA libraries, one for D and one for FR -grown samples, which were then subjected to ultra-high throughput Solexa (Illumina) sequencing
