Non-monophyly of Primula subgenera Auganthus and Carolinella (Primlaceae) as confirmed by the nuclear DNA sequence variation

Contrasting evolutionary processes during Quaternary climatic changes and historical orogenies: a case study of the Japanese endemic primroses Primula sect. Reinii

“…Cortusoides (P. sieboldii and P. jesoana) was strongly supported in Bayesian analysis (PP = 1.00), while ML analysis weakly supported this arrangement (ML = 62 %). Other phylogenetic relationships within Primula revealed in this study were generally congruent with those previously inferred from plastid trees (Yan et al, 2010;Liu et al, 2015).…”

“…Reinii were unclear in previous studies (e.g. Mast et al, 2001Mast et al, , 2006Yan et al, 2010;de Vos et al, 2014;Liu et al, 2015); however, our analyses recognized sect. Reinii as a robust monophyletic group and a sister taxon to sect.…”

“…Incongruence between chloroplast and nuclear phylogenies could be attributed to hybridization, introgression and/or incomplete linage sorting, considering the most common cases in the phylogenetic studies of Primula (e.g. Liu et al, 2015;Ren et al, 2015). The specific cause of the incongruence could be identified by determining the correct genealogy using multiple nuclear markers or larger data sets [e.g.…”

Morphological and Molecular Phylogenetic Data Reveal a New Species of Primula (Primulaceae) from Hunan, China

“…Some of the diagnostic characters, such as the calyptrate capsule, might have evolved more than once in Primula , even in Primulaceae [14, 15]. The subgen.…”

“…Recently, some molecular phylogenetic analyses focusing on Primula have found that most of the subgenera and sections in the traditional subgeneric classification of Primula were non-monophyletic [ 5 , 7 , 13 , 14 ]. Some of the diagnostic characters, such as the calyptrate capsule, might have evolved more than once in Primula , even in Primulaceae [ 14 , 15 ]. The subgen.…”
