Project description:One of the most distinct features of Pseudoalteromonas sp. SCSIO 11900 is its ability to form a very robust pellicle than most Pseudoalteromonas strains. Thus we want to identify the genes essential for the pellicle formation of SCSIO 11900. We compared transcriptom profiles of planktonic cells, initial pellicle and mature pellicle of coral Pseudoalteromonas sp. SCSIO 11900 and revealed that some unique genes from horizontal gene transfer is involved in the pellicle formation of SCSIO 11900.

Project description:We compared genetic profiles of planktonic stage to biofilm stage of deep sea bacterium Pseudoalteromonas sp. SM9913 and revealed genetic features during switch from planktonic to pellicle stage in Pseudoalteromonas sp. SM9913. mRNA profiles of Pseudoalteromonas sp. SM9913 planktonic cells, initial pellicle cells and mature pellicle cells were generated by Illumina Hiseq2000.

Project description:Marine-derived fungi represent anunderexplored sourceofmonoterpenes, withonlysporadicreportsover thepast twodecades,makingtheir discovery particularlychallenging.Whole-genomesequencing of Diaporthesp. SYSU MS4722,anascidian-derivedfungusisolatedfromStyelaplicata, identified130 biosyntheticgeneclusters(BGCs),underscoringitsvastbiosyntheticpotential. However, previous studies demonstrated that Diaporthe sp. SYSU-MS4722 predominantlyproduces xanthone phomoxanthone A understandardlaboratory conditions, suggestingthatmanyBGCs remaincryptic.Notably, 16 of these BGCs encode terpene synthase genes, indicatingthepotentialformonoterpene biosynthesis. To activate these silent BGCs and discover monoterpenes, we deleted sthe polyketide synthase (PKS) gene phoE, responsible for phomoxanthoneAbiosynthesis, generating themutant strainDiaporthe sp. SYSU-MS4722 phoE, fromwhich threenewmonoterpenes, diaporterpenes D-F (1-3), three knownmonoterpenes (4-6), and twonewpolypropionate derivatives, diaporpolypropionateA (7) anddiaporpolypropionateB (8),were isolated.Compounds1,4, 7, and8wereevaluatedfor theircytotoxicityand anti-inflammatory effects inhumannon-small cell lungcancer A549cells.

Project description:Transcriptomic sequencing was performed to obtain the key functional genes involved in the adaptation of oxidative stress induced by hydrogen peroxide (H2O2) in the Arctic bacterium Pseudoalteromonas sp. A2. Exposure to 1 mmol/L H2O2 resulted in large alterations of the transcriptome profile, including significant upregulation of 109 genes and significant downregulation of 174 genes. Functional classification of differentially expressed genes revealed that most of genes affiliated with biological adhesion, negative regulation of biological process, enzyme regulator activity, protein binding transcription factor activity and structural molecular activity were upregulated, and most of genes affiliated with multicellular organismal process and extracellular region were downregulated. It was notably that fifteen genes affiliated with flagella and four genes affiliated with heat shock proteins were significantly upregulated. Meanwhile, nine genes affiliated with cytochrome and cytochrome oxidase, and five genes affiliated with TonB-dependent receptor, were significantly downregulated. However, eighteen genes with antioxidant activity categorized by GO analysis showed differential expressions. This overall survey of transcriptome and oxidative stress-relevant genes can contribute to understand the adaptive mechanism of Arctic bacteria. five significant upregulated genes and five significant downregulated genes were selected using qRT-PCR to cinduct the oxidative stress. overall survey of transcriptomic sequencing by RNA-Seq of the Pseudoalteromonas sp.
