Project description:Desert microbial communities live in a pulsed ecosystem shaped by isolated and rare precipitation events. The Namib desert is one of the oldest continuously hyperarid ecosystems on Earth. In this study, surface microbial communities of open soils (without sheltering features like rocks, vegetation or biological soil crusts) are analysed. We designed an artificial rainfall experiment where a 7x7 (3.5 x 3.5 m) plot remained dry while an adjacent one received a 30 mm simulated rain. Samples were taken randomly in parallel from both plots at 10 min, 1 h, 3 h, 7 h, 24 h and 7 days after the watering moment. Duplicate libraries were generated from total (rRNA depleted) RNA and sequenced 2x150 bp in an Illumina Hiseq 4000 instrument.

Project description:Impact of karst rocky desertification and vegetation restoration on soil microbial communities
Project description:An archaeological bone fragment from Baishiya Karst Cave, China, was identified as stemming from a hominin through ZooMS (Zooarchaeology by Mass Spectrometry). Shotgun palaeoproteomic analyses were thereafter conducted on the specimen to refine the taxonomic identification and perform phylogenetic analyses. The reconstruted proteome shows that the newly described Baishiya Karst Cave individual, Xiahe 2, is most closely related to the high-coverage published genome from a Denisovan individual.
Project description:Infective endocarditis results in the growth of a vegetative mass on native or bio prosthetic valves hindering function and increasing risk of thromboses. This study set out to determine the proteomic composition of these vegetations including the influence of different micro-organisms and the proteases known to be present. Our data has allowed us to describe for first time the influence different infectious organisms have on vegetation growth. Including the contribution the immune response and circulatory proteins/cells make in composing a vegetation. Furthermore, we describe the protease activity and both known and novel cleavage sites in a plethora of targets. This data provides a deep insight into the homogeneity and heterogeneity of vegetation composition.
