Project description:We investigated light dependent gene expression changes in the marine ochrophyte Nannochloropsis oceanica CCMP1779. These algae have several putative blue light photoreceptors but appear to lack red light photoreceptors. To study early light signaling in N. oceanica and avoid as much as possible secondary downstream events, we quantified gene expression changes in dark-adapted cells after a short blue or red light pulse. More genes were differentially expressed under blue than under red light. In addition, fold change in expression was smaller for the red light-treated samples. For example, the median fold change of induced genes was 3 for blue light and 2.5 for red light. Moreover, hierarchical cluster analysis showed that gene expression after red light treatment was more similar to the dark control than after blue light treatment.

Project description:The absorption of visible light in aquatic environments has led to the common assumption that aquatic organisms sense and adapt to penetrative blue/green light wavelengths, but show little or no response to the more attenuated red/far-red wavelengths. Here we show that two marine diatom species, Phaeodactylum tricornutum and Thalassiosira pseudonana, possess a bona fide red/far-red light sensing phytochrome (DPH) that uses biliverdin as a chromophore and displays accentuated red-shifted absorbance peaks compared to other characterized plant and algal phytochromes. Exposure to both red and far-red light causes changes in gene expression in P. tricornutum and the responses to far-red light disappear in DPH knockout cells, demonstrating that P. tricornutum DPH mediates far-red light signaling. The identification of DPH genes in diverse diatom species widely distributed along the water column further emphasizes the ecological significance of far-red light sensing, raising questions about the sources of far-red light. Our analyses indicate that, although far-red wavelengths from sunlight are only detectable at the ocean surface, chlorophyll fluorescence and Raman scattering can generate red/far-red photons in deeper layers. This study opens up novel perspectives on phytochrome-mediated far-red light signaling in the ocean and on the light sensing and adaptive capabilities of marine phototrophs.

Project description:Analysis of etiolated seedlings exposed for 1hr to red light. Phytochromes are red/far-red light receptors, palying important roles in photomorphogenesis. Results suggest that red light and phytochromes regulate a set of genes' expression in seedlings.

Project description:Red light can affect a variety of responses in Arabidopsis. We characterize the early gene expression patterns of roots exposed to 1 hour of red light. Early genes indicate elements involved in photomorphogenesis, chloroplast development, PAL pathways, root hair development are regulated by 1 hour of red light We used microarrays to detail the gene expression underlying the effects of red light on roots.

Project description:A comparative profile of miRNAs in pectoral muscle during pigeon development was performed by using high-throughput sequencing. We identified known pigeon miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals.Our results expanded the repertoire of pigeon miRNAs and may be of help in better understanding the mechanism of squab’s rapid development.
