The genus Capparis L. (Capparaceae) in Laos and Cambodia
2023
SummaryA taxonomic revision of the genus Capparis in Laos and Cambodia was undertaken. Based on examination of historical and recent herbarium collections coupled with field investigations, 25 species and 7 intraspecific taxa, all belonging to sect. Monostichocalyx, were recognised in the study area. Among these, a new species, C. averyanovii, and a new subspecies, C. acutifolia subsp. thamphae, from central and northern Laos are described and illustrated. A key to the species is provided, along with descriptions, synonyms, distribution ranges, autecological and phenological data, and 31 lectotypes are selected. When available, vernacular names and traditional uses of the species are also g…
The genus Mauritanica O. Boettger, 1879 (Gastropoda Stylommatophora Clausiliidae) in Tunisia
2020
Currently, the genus Mauritanica O. Boettger, 1879 (Gastropoda Stylommatophora Clausiliidae) is widespread in north-eastern Algeria and central-northern Tunisia with six taxa. The taxonomic position of this genus has often been interpreted differently and the relationship with other similar genera, in particular with Siciliaria Vest, 1867, still remains to be clarified. In this paper, we provide a further contribution to the knowledge of Mauritanica by analyzing morphologically (shell, genitalia, and the type museum material) all the known Tunisian populations. In particular, the geographical spread and taxonomy of M. tristrami s.l. (L. Pfeiffer, 1861), M. philora s.l. (Letourneux, 1887), M…
Genome-based analyses reveal a synonymy among Halorubrum distributum Zvyagintseva and Tarasov 1989; Oren and Ventosa 1996, Halorubrum terrestre Vento…
2020
A comparative taxonomic study of Halorubrum distributum , Halorubrum terrestre , Halorubrum arcis and Halorubrum litoreum was carried out using different approaches, 16S rRNA gene sequence analysis, multilocus sequence analysis (MLSA), phylogenomic analysis based on the comparison of the core genome, orthologous average nucleotide identity (OrthoANI), Genome-to-Genome Distance Calculator (GGDC), synteny plots and polar lipid profile (PLP). The MLSA study, using the five concatenated housekeeping genes atpB, EF-2, glnA, ppsA and rpoB′, and the phylogenomic analysis based on 1347 core translated gene sequences obtained from their genomes showed that Halorubrum distributum JCM 9100T, Halorubru…
Chryseobacterium potabilaquae sp. nov., Chryseobacterium aquaeductus sp. nov. and Chryseobacterium fistulae sp. nov., from drinking water systems
2021
A polyphasic taxonomic study was conducted on three strains isolated from drinking water systems that had previously been deposited as Chryseobacterium species at the Spanish Type Culture Collection in order to complete their classification. Strains CECT 9293T, CECT 9390T and CECT 9393T were isolated from sites in Barcelona, Spain, in the framework of a project aimed at generating the first MALDI-TOF database specific for bacteria present in water for human consumption. Their partial 16S rRNA sequences showed that their closest relatives among the type strains of Chryseobacterium exhibited 98 % similarity or less, supporting their taxonomic novelty. At the same time, comparison between them…
