Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

TAXON, EarlyView.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Evolutionary relationships in Panicoid grasses based on plastome phylogenomics (Panicoideae; Poaceae) [PDF]

, 2016
Background: Panicoideae are the second largest subfamily in Poaceae (grass family), with 212 genera and approximately 3316 species. Previous studies have begun to reveal relationships within the subfamily, but largely lack resolution and/or robust ...

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

TAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Membranous Interacting Partners of Phage-Type Plastid RNA Polymerase Have Limited Impact on Plastid Gene Expression During Chloroplast Development. [PDF]

Plant Direct
ABSTRACT In vascular plants, genes in the plastid genome are transcribed by two types of RNA polymerases, namely, phage‐type nuclear‐encoded and bacterial‐type plastid‐encoded plastid RNA polymerases (NEP and PEP, respectively). Eudicots, including Arabidopsis, carry two isoforms of NEP, RPOTp and RPOTmp.

A molecular phylogenetic study of Deschampsia (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of Avenella and Vahlodea [PDF]

, 2007
The circumscription and phylogeny of Deschampsia were studied for the first time by parsimony analysis of nuclear ribosomal internal transcribed spacer (ITS) and plastid trnL intron sequences.

Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

TAXON, EarlyView.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Evolutionary History and Taxonomy of the \u3cem\u3eCuscuta umbellata\u3c/em\u3e complex (Convolvulaceae): Evidence of Extensive Hybridization from Discordant Nuclear and Plastid Phylogenies [PDF]

, 2010
The Cuscuta umbellata complex is one of the 15 major clades recently circumscribed in C. subg. Grammica. Most of its members occur in North AMerican and the Caribbean (C. desmouliniana, C. lacerata, C. lacerata, C. leptantha, C.
