Tuber Species

Three excavated truffle species Tuber badium, T. depressum and T. verrucosivolvum were described and illustrated from southwest China. Molecular analyses based on ITS and ITS-nrLSU concatenated dataset revealed that these species are distinct from the known ones of Tuber. Tuber badium, T. depressum and T. verrucosivolvum differ from other species of Tuber in a combination of morphologically features including ascoma, gleba and ascospore. Phylogenetic placements of these novel Tuber species in the Excavatum group are presented.

A New Species

AbstractBioblapsís mallochi sp. n., from Scotland is described and a key is given to adult Bioblapsis. The host of B. mallochi is the syrphid Cheilosía longula, which breeds in fruiting bodies of Boletus fungi growing in the ground flora of pinewoods. The host of Bioblapsis polita (Vollenhoven) appears to be species of the hoverfly genus Ferdinandea which are associated with sap-flows on deciduous trees. These are unusual host species for diplazontines which are more typically associated with predacious hoverflies.

Plasmid Conjugation

By transferring ecologically important traits between species, plasmids drive genomic divergence and evolutionary innovation in their bacterial hosts. Bacterial communities are often diverse and contain multiple coexisting plasmids, but the dynamics of plasmids in multi-species communities are poorly understood. Here, we show, using experimental multi-species communities containing two plasmids, that bacterial diversity limits the horizontal transmission of plasmids due to the ‘dilution effect’; this is an epidemiological phenomenon whereby living alongside less proficient host species reduces the expected infection risk for a focal host species. In addition, plasmid horizontal transmission was also affected by plasmid diversity, such that the rate of plasmid conjugation was reduced from co-infected host cells carrying both plasmids. In diverse microbial communities, plasmid spread may be limited by the dilution effect and plasmid–plasmid interactions, reducing the rate of horizontal transmission.

Culture Characteristics

A dead woody sample of Acer sp. with fungal fruiting bodies was collected in Pu’er City of Yunnan Province. Multigene phylogenetic analyses of LSU, ITS, SSU, and tef1-α sequence data showed that our collection belongs to Montagnula and is well separated from all other extant species. Montagnula puerensis is compared with all extant species by morphological characteristics, culture characteristics, host, and location information and is the first report of Montagnula from the host genus Acer.

A New Species

Scutellaria wuana, a new species discovered from a xeric valley in Muli County of Sichuan Province in southwest China, is described and illustrated. Morphologically, the new species shares similarities withS. mairei, but can be readily distinguished by a suite of morphological characters including a white-pubescent erect stem, conspicuous leaf petioles, and a yellow corolla with a trapeziform lower-middle lip lobe. The habitat and distribution ofS. wuanaare also distinctive. The position of the new species withinScutellariais examined in a phylogenetic context using the nuclear ribosomal internal and external transcribed spacers. Additionally, we examine leaf epidermal and pollen grain micromorphology of the new species and putative relatives.

Diverse bacterial communities are found on every surface of macro-organisms, and they play important roles in maintaining normal physiological functions in their hosts. While the study of microbiomes has expanded with the influx of data enabled by recent technological advances, microbiome research in reptiles lags behind other organisms. We sequenced the nasal microbiomes in a sample of four North American tortoise species, and we found differing community compositions among tortoise species and sampling sites, with higher richness and diversity in Texas and Sonoran desert tortoises. Using these data, we investigated the prevalence and operational taxonomic unit (OTU) diversity of the potential pathogen Pasteurella testudinis and found it to be common, abundant and highly diverse. However, the presence of this bacterium was not associated with differences in bacterial community composition within host species. We also found that the presence of nasal discharge from tortoises at the time of sampling was associated with a decline in diversity and a change in microbiome composition, which we posit is due to the harsh epithelial environment associated with immune responses. Repeated sampling across seasons, and at different points of pathogen colonization, should contribute to our understanding of the causes and consequences of different bacterial communities in these long-lived hosts.
