Project description:Background Sporothrix brasiliensis and Sporothrix schenckii are the main etiological agents of sporotrichosis. These pathogens release extracellular vesicles (EVs), which are key transport structures involved in virulence and host–pathogen interactions. EVs from S. brasiliensis and S. schenckii have been exclusively under liquid culture conditions, with analyses focused on their protein composition and functional roles. However, noinformation is currently available regarding the small molecule composition of Sporothrix EVs, and the extent to wich S. schenckii and S. brasiliensis share or differ in their EVs cargo remain unknown. Methods We isolated EVs from S. brasiliensis (strain 5110) and S. schenckii (strain 1099-18) following cultivation on solid medium, and characterized the samples using a combination of nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), proteomics, and small molecule identification. Based on the EV composition, subsequent analyses included biochemical assay to assess cell-assocaited enzyme activity and a functional model of Sporothrix adhesion to type I collagen in the presence of isoleucine-proline-isoleucine (IPI), a peptide component found in EVs produced by both S. schenckii and S. brasiliensis. Results EVs from both S. brasiliensis and S. schenckii exhibited a high protein diversity, encompassing components related to essential cellular processes and virulence mechanisms. Only a small fraction of the identified proteins was shared between the two species, and a similar pattern was observed for the small molecules. Among the common molecules was IPI, previously described in Cryptococcus EVs. IPI is an inhibitor of dipeptidyl peptidase IV (DPP4), which was detected on the surface of S. brasiliensis and S. schenckii. Both IPI and an antibody against DPP4 effectively reduced Sporothrix adhesion to type I collagen, a major component of the host extracellular matrix. Conclusion Our study reveals an unprecedented level of proteomic and metabolomic complexity in Sporothrix EVs, uncovering novel molecular features and identifying IPI as an inhibitor of fungal adhesion to collagen.

Project description:We first report the use of next-generation massively parallel sequencing technologies and de novo transcriptome assembly to gain insight into the wide range of transcriptome of Hevea brasiliensis. The output of sequenced data showed that more than 12 million sequence reads with average length of 90nt were generated. Totally 48,768 unigenes (mean size = 488 bp) were assembled through transcriptome de novo assembly, which represent more than 3-fold of all the sequences of Hevea brasiliensis deposited in the GenBank. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. Total 37,373 unigenes were successfully annotated and more than 10% of unigenes were aligned to known proteins of Euphorbiaceae. The unigenes contain nearly complete collection of known rubber-synthesis-related genes. Our data provides the most comprehensive sequence resource available for study rubber tree and demonstrates the availability of Illumina sequencing and de novo transcriptome assembly in a species lacking genome information.

Project description:We report here the use of next-generation massively parallel sequencing technologies and de novo transcriptome assembly to gain insight into the wide range of transcriptome of two Hevea brasiliensis clones (RY8-79 and PR107). The output of sequenced data showed that more than 26 million sequence reads with average length of 90nt were generated in both clones. Totally 51829 unigenes (mean size = 640 bp) were assembled through transcriptome de novo assembly, which represent more than 16-fold of all the sequences of Hevea brasiliensis deposited in the GenBank. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. Base on limit rule with FDR≤0.001 and |log2 Ratio|≥1, 6726 different expression unigenes (3018 up and 3708 down) were detected as PR107 versus RY8-79. Functional analysis showed mass of categories were reprogrammed between two clones, which relate latex generation and expelling difference between them. As a comparative transcriptome analysis, the results obtained here will greatly expand our understanding of physiological differences among varieties in molecular level and will contribute t The transcriptome of latex in Hevea brasiliensis
