Selaginelladianzhongensis (Selaginellaceae), a new spikemoss from China.

ABSTRACT: A new species of spikemoss from Yunnan Province of China, Selaginelladianzhongensis, is described and illustrated based on evidence from gross morphology, micromorphology and molecular phylogeny. S.dianzhongensis is most similar to S.amblyphylla in its habit of creeping stem, leaf size, and obviously dimorphic sporophylls, but is distinct by its ventral leaves ovate-oblong, subcordate at base, basiscopic base entire, axillary leaves ovate and decurrent at base. Molecular phylogeny analysis of three chloroplast gene regions (rbcL, atpI, psbA) shows that S.dianzhongensis forms an independent branch with strong support which is distantly related to S.amblyphlla and S.kurzii, but sister to S.bodinieri which is quite different in habitat of erect or ascending stem and rhizophores restricted to the lower part, and slightly dimorphic sporophyllus.

Project description:We describe seven new species of Selaginellasubg.Stachygynandrum (Selaginellaalstonii, Selaginellablepharodella, Selaginellacrinita, Selaginellamucronata, Selaginellamucugensis, Selaginellasaltuicola, and Selaginellasematophylla) from Brazil and discuss their possible affinities and conservation status. Scanning electron micrographs of stem sections, leaves, and spores are provided to illustrate the new taxa. In Selaginellaalstonii and Selaginellasaltuicola vegetative growth from strobilus tips is reported and discussed. Four of the new species are from the Espinhaço Mountain Range associated with Campos Rupestres (montane savannah/rocky fields) vegetation. Three of these (i.e., Selaginellablepharodella, Selaginellacrinita, and Selaginellamucugensis) were collected in the northern part of the range in Chapada Diamantina, state of Bahia, while Selaginellaalstonii is from the southern part of the range in the state of Minas Gerais. Selaginellamucronata is found in Atlantic Rainforest vegetation in the state of Espírito Santo, whereas Selaginellasaltuicola inhabits Cerrado (tropical savannah) vegetation in the state of Mato Grosso. Selaginellasematophylla is the most widely distributed of the new species and was collected in Espírito Santo, Minas Gerais, and Rio de Janeiro states in Campos Rupestres and Atlantic Rainforest vegetation. Selaginellaalstonii occurs in rocky caves, Selaginellablepharodella, Selaginellacrinita, Selaginellamucugensis, and Selaginellasematophylla seem adapted to seasonally dry places, living on sandy or humid soils, Selaginellamucronata occupies humid, forest understory, and Selaginellasaltuicola is adapted to wet places associated with rocks or logs in waterfalls. Of the seven new species, six are considered local endemics (except for Selaginellasematophylla) because of their restricted currently known distributions to one or two localities within a single state in Brazil. Additionally, we propose new synonymy for Selaginellapalmiformis (syn. = Selaginellabahiensissubsp.manausensis, ? Selaginellamanausensis) and Selaginellavestiens (syn. = Selaginellafragillima); the last species is endemic to Brazil, recorded in the states of Goiás and Minas Gerais. Finally, based on literature discussed and this study, we conclude that the number of well-documented Brazilian Selaginella species is 61, of which 58 are native and three introduced and naturalized. These statistics are likely to change with further work on Selaginella from Brazil.

Project description:Yunnan Province, China is thought to be the original source of biovar Orientalis of Yersinia pestis, the causative agent of the third plague pandemic that has spread globally since the end of the 19th century. Although encompassing a large area of natural plague foci, Y. pestis strains have rarely been found in live rodents during surveillance in Yunnan, and most isolates are from rodent corpses and their fleas. In 2017, 10 Y. pestis strains were isolated from seven live rodents and three fleas in Heqing County (HQ) of Yunnan. These strains were supposed to have low virulence to local rodents Eothenomys miletus and Apodemus chevrieri because the rodents were healthy and no dead animals were found in surrounding areas, as had occurred in previous epizootic disease. We performed microscopic and biochemical examinations of the isolates,and compared their whole-genome sequences and transcriptome with those of 10 high virulence Y. pestis strains that were isolated from the adjacent city (Lijiang). We analyzed the phenotypic, genomic, and transcriptomic characteristics of live rodent isolates. The isolates formed a previously undefined monophyletic branch of Y. pestis that was named 1.IN5. Six SNPs, two indels, and one copy number variation were detected between live rodent isolates and the high virulence neighbors. No obvious functional consequence of these variations was found according to the known annotation information. Among the genes that were differentially expressed between the live rodent isolates and their high virulence neighbors, we detected five iron transfer-related genes that were significantly up-regulated in live rodent isolates compared with high virulence isolates (|log2 (FC) | >1, p.adjust <0.05), indicating these genes may be related to the low-virulence phenotype. The novel genotype of Y. pestis reported here provides further insights into the evolution and spread of plague as well as clues that may help to decipher the virulence mechanism of this notorious pathogen.
