Project description:The goal of this study was to compare the transcriptional profile (RNA-seq) of imbibed Arabidopsis thaliana Columbia-0 ecotype seeds that were treated with a 20 min red or far red pulse. The red-light pulse induces germination.

Project description: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.

Project description:Transcriptional profiling of Arabidopsis far-red light pulse treated seeds comparing luh mutant with wild type (Col-0). Seeds were imbibed within 1 hr under white light and treated far-red light pulse for 5 min followed by 12 hr dark incubation. Goal was to determine the effects of LUH as transcriptional co-regulator during seed germination process.

Project description:The goal of this work was to investigate oxidative stress responses of Arabidopsis to low red to far-red ratios of light as a signal of competition using a biological weedy and an artificial source of far-red light. More specifically, elucidation of the signaling role of singlet oxygen in Arabidopsis under low red-to far-red light environments was the major objective of this work. Oxidative stress responses of Arabidopsis to low red (R) to far-red (FR) signals (R:FR ≈ 0.3), generated by a biological weedy and an artificial source of FR light, were compared with a weed-free control (R:FR ≈1.4). In the low R:FR treatments, induction of the shade avoidance responses coincided with increased singlet oxygen (1O2) production and decreased level of superoxide and superoxide dismutase activity. Although the increase of 1O2 was not due to protochlorophyllide accumulation and did not result in cell death, treatments with the 1O2 generator 5-aminolevulinic acid increased sensitivity to cell death. Transcriptome responses minimally resembled those reported in four Arabidopsis 1O2 generating systems such that only few genes (6 out of 1931) were consistently up-regulated supporting the specificity of 1O2 signaling. Moreover, suppressors of jasmonate accumulation, including the 1O2-responsive amidohydrolase ILL6, the sulfotransferase ST2a, which are involved in prioritization of elongation growth versus defense were consistently up-regulated. Our data support a model in which photoreceptors connect low R:FR light cues to the JA signaling pathway. Repression of bioactive JAs via the amidohydrolase ILL6, and sulfotransferase ST2a may promote the shade avoidance (versus defense) and 1O2 acclimation (versus cell death) responses to competition cues.
