Project description:Light is one of the main environmental cues that affects the physiology and behavior of many organisms. The effect of light on genome-wide transcriptional regulation has been well-studied in green algae and plants, but not in red algae. Cyanidioschyzon merolae is used as a model red algae, and is suitable for studies on transcriptomics because of its compact genome with a relatively small number of genes. In addition, complete genome sequences of the nucleus, mitochondrion, and chloroplast of this organism have been determined. Together, these attributes make C. merolae an ideal model organism to study the response to light stimuli at the transcriptional and the systems biology levels. Previous studies have shown that light significantly affects cell signaling in this organism, but there are no reports on its blue light- and red light-mediated transcriptional responses. We investigated the direct effects of blue and red light at the transcriptional level using RNA-seq. Blue and red light were found to regulate 35% of the total genes in C. merolae. Blue light affected the transcription of genes involved protein synthesis while red light specifically regulated the transcription of genes involved in photosynthesis and DNA repair. Blue or red light regulated genes involved in carbon metabolism and pigment biosynthesis. Overall, our data showed that red and blue light regulate the majority of the cellular, cell division, and repair processes in C. merolae. Identification of blue light and red light regulated genes by deep sequencing in biological duplicates. qRT-PCR was performed to verify the RNA-seq results.

Project description:Bacteria isolated from diverse environments were found to sense blue light to regulate their biological functions. However, this ability of deep-sea bacteria has been studied rarely. In this study, we found serendipitously that blue light stimulated excess zero-valent sulfur (ZVS) production of E. flavus 21-3, which was isolated from the deep-sea cold seep and possessed a novel thiosulfate oxidation pathway. Its ZVS production responding to the blue light was mediated by a light-oxygen-voltage histidine kinase (LOV-1477), a diguanylate cyclase (DGC-2902), a PilZ protein (mPilZ-1753) and the key thiosulfate dehydrogenase (TsdA) in its thiosulfate oxidation pathway. Subsequently, the thiosulfohydrolase (SoxB-277) was found working with another SoxB (SoxB-285) and being as substitute for each other to generate ZVS. This study provided an example of deep-sea bacteria sensing blue light to regulate thiosulfate oxidation. Deep-sea blue light potentially helped these blue-light-sensing bacteria adapt harsh conditions by diversifying their biological processes.

Project description:Light was a ubiquitous environmental stimulus. Deep-sea microorganisms were exposed to a pervasive blue light optical environment. The utilization of blue light by deep-sea microorganisms, especially non-photosynthetic microorganisms, and the downstream pathway after light reception were obscure. Under the enrichment condition surrounded by blue light, a potential novel species named Spongiibacter nanhainus CSC3.9 from the deep-sea cold seep was isolated. Its growth and metabolism under blue light were significantly better than other wavelengths of light. Six blue light sensing proteins, including four BLUF (Blue Light Using Flavin) and two bacteriophytochrome, were annotated in the genome of strain CSC3.9. Then, with the assist of proteomic analysis, we demonstrated that 15960-BLUF was a crucial blue light receptor that interfered with motor behavior through chemotaxis pathway by means of in vivo and in vitro verification. In addition, 15960-BLUF mediated part of the blue light to promote the growth of strain CSC3.9. Further, we summarized the functional BLUF proteins from isolated marine microorganisms, and the high abundance distribution of BLUF similar to the downstream unresponsive domain type in strain CSC3.9 was demonstrated. The widespread distribution of BLUF protein in marine bacteria implied the extensiveness of this regulatory mechanism, and wavelength variation of light was a potential means to isolate uncultured microorganisms. This was the first reported in deep-sea microorganisms that BLUF-dependent physiological response to blue light. It provided a new clue for the blue light adaptation of microorganisms in disphotic zone.

Project description:Although many regulatory components of light signaling have been functionally characterized, only a few of them have been reported to cross talk with other signaling cascades. In this study, we have analyzed the expression profiles of Arabidopsis genes in wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant seedlings grown under constant dark, constant blue-light, and constant blue-light along with abscisic acid (ABA) to illustrate the interplay of negative regulators, AtMYC2 and COP1, in light and ABA signaling Keywords: Light and abscisic acid treatment Expression data for wild-type, atmyc2, cop1-6, and atmyc2 cop1-6 seedlings under constant dark, blue-light and blue-light along with abscisic acid Ten-day-old Arabidopsis (wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant) seedlings grown under constant dark, constant blue-light (35 µmol/sec/m2), and constant blue-light along with ABA (0.5 µm) were used for RNA extraction and hybridization on Affymetrix microarrays. Two biological replicates of each sample were used for microarray analysis.
