“…The spores are lighter coloured on one side, collapsed and cracked (because of the thinner spore wall) in both Pattersoniomyces and some Tranzscheliella species (Vánky 2012;Li et al 2017). However, the finely ridged spore surface is unique to Pattersoniomyces tillandsiae.…”

“…The anamorphic stage of this fungus is reported in an area of Atlantic rain forest of northeast Brazil associated with the endemic species Canistrum improcerum (Martinelli et al 2008), and in a small area in southeast Brazil associated with the endemic and endangered species Vriesea minarum (Versieux 2011;Gomes et al 2015). Considering the usually high level of host specificity of smut fungi in the teleomorphic stage (e.g., Hendrichs et al 2005;Piątek et al 2011Piątek et al , 2013Piątek et al , 2016Li et al 2017), it is not likely to find the teleomorph of P. tillandsiae outside its current area of host distribution. Future studies should question whether the anamorphic stage is indeed restricted to C. improcerum and V. minarum or if it may be also associated with other bromeliads or other habitats.…”

“…Scale bars: a = 10 μm, b-e = 5 μm thin peridium, in Tranzscheliella (Vánky 2012(Vánky , 2013Li et al 2017). However, sori in Pattersoniomyces are restricted to flowers of hosts in the Bromeliaceae and destroy the innermost floral organs-staminal filaments and ovaries remain partly intact in the sorus centre (this study), while the sori in Tranzscheliella are produced on stems or, rarely in all aborted inflorescence branches of hosts in Poaceae (Vánky 2012(Vánky , 2013Li et al 2017). The soral characters appear to be an important feature to delimit smut genera, likewise demonstrated for smuts of the Ustilago-Sporisorium-Macalpinomyces complex (McTaggart et al 2012a, b, c).…”

Pattersoniomyces tillandsiae gen. et comb. nov.: linking sexual and asexual morphs of the only known smut fungus associated with Bromeliaceae

The enigmatic species Ustilago tillandsiae is the only known smut fungus associated with Bromeliaceae. Its generic position is evaluated by morphological, physiological, and molecular phylogenetic analyses using large subunit rDNA sequences. Phylogenetic analyses resolved U. tillandsiae as a member of the Ustilaginales in a sister relationship to the lineage containing Tranzscheliella species. However, U. tillandsiae differs from Tranzscheliella species by the development of sori in flowers, a different structure of sori and a different type of spore ornamentation. Consequently, a new genus Pattersoniomyces is described to accommodate U. tillandsiae. The new combination Pattersoniomyces tillandsiae is substantiated. In the sexual stage (teleomorph), this species infects bromeliads: Tillandsia flabellata, Tillandsia leiboldiana, and Tillandsia sp. in Central America between southern Mexico and Costa Rica. The yeast stage (anamorph) of P. tillandsiae was found associated with the phylloplane of Canistrum improcerum and in water tanks (phytotelmata) of Vriesea minarum, two bromeliads occurring in northeast and southeast Brazil, respectively. The link between the teleomorph and anamorphic strains is supported by identical sequences of the D1/D2 domains of the large subunit rDNA. Pattersoniomyces represents the tenth endemic smut genus to the Americas, but the only one that occurs in both North and South America, being a truly neotropical genus. The host plant families of Ustilaginales are extended to the Bromeliaceae. As far as we know, Pattersoniomyces represents the single event of a host jump from Cyperaceae or Poaceae to Bromeliaceae, apparently without further species radiation on multiple bromeliad species and genera growing in South America.

Background: Wolbachia is an intracellular bacterial endosymbiont found in most insect lineages. In mosquitoes, the endosymbiont’s influence on host reproduction and arboviral transmission has spurred numerous studies aimed at using Wolbachia-infection as a vector control technique. However, there exist several gaps in the literature regarding the natural Wolbachia infection across species, modes of transmission as well as the associations between various Wolbachia lineages and their hosts. This study aims to address these by exploring mosquito-Wolbachia associations and their evolutionary implications.Methods: We conducted tissue-specific PCR screening of Wolbachia infection in wild mosquitoes from Singapore using the wsp molecular marker. Tissues examined include leg, gut, and reproductive tissues. We also explored mosquito-Wolbachia associations using three methods – a tanglegram, distance-based, and event-based method, and inferred instances of vertical transmission and host shifts. Results: We screened 271 adult mosquitoes (41 species and 14 genera) for Wolbachia and found that 43.9% of all individuals harboured Wolbachia. Eight out of the 21 infected species were not previously reported. We detected Wolbachia infections predominantly in the reproductive tissues, a strong indication of vertical transmission. Despite this, Wolbachia infection rates vary widely within a mosquito host species. There was no clear signal of co-phylogeny between the mosquito hosts and the twelve putative Wolbachia strains observed in our study. Host shift events were also observed. Conclusions: Our results suggest that the mosquito-Wolbachia relationship is complex and that a combination of transmission modes and multiple evolutionary events likely explain the distribution of Wolbachia diversity observed across mosquito hosts. This has implications towards understanding Wolbachia’s diversity, ecology, and utility as a biocontrol method.

The origin and diversification of the Entorrhizales: deep evolutionary roots but recent speciation with a phylogenetic and phenotypic split between associates of the Cyperaceae and Juncaceae

Fungi belonging to the Entorrhizales (Entorrhizomycota) comprise biotrophic pathogens associated with roots of the Cyperaceae and Juncaceae plant species. They are nearly globally distributed but rarely studied due to a hidden lifestyle without causing visible effects on host plants. Therefore, the evolutionary origin and phylogenetic relationships of the group are still poorly understood and it is not known whether species diversification was the result of co-evolution with their hosts or the result of host jumps. To infer hypotheses about the evolutionary history of the Entorrhizales, divergence times were estimated and plant-fungal tanglegrams calculated. Relaxed molecular clock analyses suggest that the Entorrhizomycota originated around the Neoproterozoic-Palaeozoic and diverged during the Late Cretaceous-Paleogene into the extant orders Entorrhizales and Talbotiomycetales. The split of the major lineages within the Entorrhizales took place in the Eocene, somewhat later than the divergence of the host families Cyperaceae and Juncaceae. Topology-and distance-based co-phylogenetic analyses of the fungi and their hosts revealed a large number of co-speciation and lineage sorting events in early fungal speciation, which resulted in a phylogenetic split corresponding to species infecting Cyperaceae or Juncaceae. Given that this split is congruent with spore differences, Entorrhiza s. str. is emended for species infecting hosts in the Cyperaceae, and a new genus Juncorrhiza is described for species restricted to hosts in the Juncaceae. Additionally, three new species are described: Entorrhiza fuirenae, Juncorrhiza maritima and J. oxycarpi.
