Taxonomic and phylogenetic studies of were carried out on the basis of morphological differences and molecular phylogenetic analyses. Based on the phylogeny inferred from the internal transcribed spacer (ITS), the partial large subunit nuclear ribosomal DNA (nrLSU), the second largest subunit of RNA polymerase II () and translation elongation factor 1-α () sequences, six well-supported clades and 17 phylogenetic species are recognised. Within this phylogenetic framework and considering the diagnostic morphological characters, two new species, and , are described. In addition, a new infrageneric classification of is proposed, in which the genus is divided into six sections. One new combination is also made. This study provides a robust basis for a more detailed investigation of diversity and biogeography of .

The application of DNA data on a worldwide sampling has revolutionized the infrageneric classification of the highly diverse ectomycorrhizal genus . Based on collections made in New Zealand, East Asia and North America, this study describes a new subgenus , the ninth subgenus of . Even though BLASTn of the ITS sequences suggested affinities with species of subgenera and the phylogenetic analysis based on a five-locus DNA dataset placed the target samples in an independent major clade that is taxonomically equivalent to subgenus.

Background And Aims: Kalanchoe is a diverse genus in the Crassulaceae, with centres of diversity in Madagascar and sub-Saharan Africa. The genus is known for its popularity in horticulture, its use as a model system for research on CAM photosynthesis and vegetative reproduction, its high invasive potential, and its use in traditional medicine. The genus-rank circumscription and infrageneric classification of Kalanchoe have been the subject of debate for centuries, especially regarding the status and rank of what is now treated as K.

Background: The monogeneric family Selaginellaceae is made up of about 700 species distributed throughout the world, but the most concentrated part is in tropical and subtropical areas. According to the most recent infrageneric classification of the genus , six or seven subgenera can be recognised and perhaps 700 species. The genus is monophyletic, cosmopolitan, characterised by the presence of rhizophores, ligulated leaves and has a reniform adaxial sporangia with two type of spores (heterospory).

Sexual compatibility in the Basidiomycota is governed by genetic identity at one or two loci, resulting in compatibility systems called bipolar and tetrapolar. The loci are known as and , encoding homeodomain transcription factors and pheromone precursors and receptors, respectively. Bipolarity is known to evolve either by linkage of the two loci or by loss of mating-type determination of either the or the locus.

Article Synopsis
- Cephalanthera nanchuanica is a terrestrial orchid endemic to China and is considered a second-grade protected plant due to its limited distribution; it was reclassified from the genus Tangtsinia to Cephalanthera based on both morphological and molecular evidence.
- The complete chloroplast genome of C. nanchuanica was analyzed and found to have a typical quadripartite structure, containing 113 unique genes, with no significant structural rearrangements except for one species (C. humilis) that showed alterations due to gene loss and changes in inverted repeats.
- Phylogenetic analysis placed C. nanchuanica as closely related to C. falcata, supporting a monophy
