“…Triana's classification was adopted by many later authors (Cogniaux, ; Krasser, ; Diels, ; Li, ; Chen, ), but Van Vliet et al () proposed a broader Sonerileae mainly based on wood anatomy to include also the paleotropical tribe Oxysporeae and the neotropical tribe Bertolonieae. Later molecular phylogenetic studies showed that Sonerileae and Oxysporeae formed a close alliance nested within tribe Dissochaeteae (Clausing, ; Clausing et al, ; Clausing & Renner, , ; Renner et al, ; Fritsch et al, ; Goldenberg et al, ; Michelangeli et al, ). In this paper, we followed a circumscription of Sonerileae s.l.…”

Phyllagathis Blume and Bredia Blume (Sonerileae s.l., Melastomataceae) are two closely related Asian genera with similar morphology and overlapping geographical range. Their generic circumscription and phylogenetic relationships are far from fully understood. We present here a molecular phylogenetic investigation for the two genera using nuclear ribosomal internal transcribed spacer and chloroplast (trnV‐trnM) sequence data. Seventeen genera of Sonerileae s.l. were included in the analyses, with Phyllagathis and Bredia densely sampled to cover their geographical range and morphological diversity. We identified 14 well supported species clusters within Sonerileae s.l.–Medinilla. Phylogenetic analyses together with reconstruction of morphological characters clearly indicated the taxonomic mess in generic delimitation of Sonerileae s.l. Many of the characters traditionally used in generic delimitation were highly homoplasious. Bredia and Phyllagathis, as well as Allomorphia, Anerincleistus, Fordiophyton, and Oxyspora, were revealed to be non‐monophyletic. Bredia, as currently defined, contains two groups of species with different phylogenetic affiliations. Bredia should be recircumscribed to exclude the Bredia–Phyllagathis clade I and accommodate the Bredia–Phyllagathis clade II as the type of the genus is included in the latter clade. Most species sampled in Phyllagathis spread across eight well supported clades throughout the phylogenetic tree. The type of Phyllagathis showed no close affiliation with other members of Phyllagathis nor its putative relatives. Phyllagathis, as presently circumscribed, is heterogeneous, encompassing multiple evolutionary lineages. As sequence data of nuclear ribosomal internal transcribed spacer and chloroplast trnV‐trnM failed to resolve the phylogenetic relationships among these lineages, the formal taxonomic adjustment of Phyllagathis is postponed until further evidence can be gathered.

“…The first Melastomataceae-wide phylogeny used a plastid data set including the rbcL and ndhF genes plus the rpl16 intron (Clausing & Renner, 2001). This plastid data set is still the most employed source of information in studies focusing on generic relationships across the family (Fritsch et al, 2004; Renner, 2004; Amorim, Goldenberg & Michelangeli, 2009; Michelangeli et al, 2011; Goldenberg et al, 2012; Michelangeli, Ulloa & Sosa, 2014; Goldenberg et al, 2015; Zeng et al, 2016). Phylogenetic studies within lower lineages of Melastomataceae have predominantly used the plastid spacers accD-psaI , atpF-atpH , psbK-psbI , and trnS-trnG , along with the ribosomal spacers nrETS and nrITS (Bécquer-Granados et al, 2008; Reginato, Michelangeli & Goldenberg, 2010; Kriebel, Michelangeli & Kelly, 2015; Reginato & Michelangeli, 2016).…”

“…Early studies have consolidated the sister relationship of Olisbeoideae and the remaining Melastomataceae, settling on the currently accepted family circumscription (Conti, Litt & Sytsma, 1996; Angiosperm Phylogeny Group, 1998; but see Clausing & Renner, 2001 for a different perspective). Latter studies focused in some tribal re-arrangements (Fritsch et al, 2004; Penneys et al, 2010; Michelangeli et al, 2011), generic placement (Amorim, Goldenberg & Michelangeli, 2009; Goldenberg et al, 2012; Michelangeli, Ulloa & Sosa, 2014; Goldenberg et al, 2015; Kriebel, 2016; Rocha et al, 2016; Zeng et al, 2016), phylogenetic evaluation of higher species-rich lineages (Michelangeli et al, 2004; Stone, 2006; Goldenberg et al, 2008; Martin et al, 2008; Michelangeli et al, 2008; Michelangeli et al, 2013), and lower taxon phylogenies (Bécquer-Granados et al, 2008; Reginato, Michelangeli & Goldenberg, 2010; Penneys, 2013; Kriebel, Michelangeli & Kelly, 2015; Gamba-Moreno & Almeda, 2014; Majure et al, 2015; Reginato & Michelangeli, 2016). Even in family-wide phylogenies, the level of variation across these few sampled plastid markers is unsatisfactory, as evidenced by low statistical support among many relationships in different published analyses.…”

BackgroundIn the past three decades, several studies have predominantly relied on a small sample of the plastome to infer deep phylogenetic relationships in the species-rich Melastomataceae. Here, we report the first full plastid sequences of this family, compare general features of the sampled plastomes to other sequenced Myrtales, and survey the plastomes for highly informative regions for phylogenetics.MethodsGenome skimming was performed for 16 species spread across the Melastomataceae. Plastomes were assembled, annotated and compared to eight sequenced plastids in the Myrtales. Phylogenetic inference was performed using Maximum Likelihood on six different data sets, where putative biases were taken into account. Summary statistics were generated for all introns and intergenic spacers with suitable size for polymerase chain reaction (PCR) amplification and used to rank the markers by phylogenetic information.ResultsThe majority of the plastomes sampled are conserved in gene content and order, as well as in sequence length and GC content within plastid regions and sequence classes. Departures include the putative presence of rps16 and rpl2 pseudogenes in some plastomes. Phylogenetic analyses of the majority of the schemes analyzed resulted in the same topology with high values of bootstrap support. Although there is still uncertainty in some relationships, in the highest supported topologies only two nodes received bootstrap values lower than 95%.DiscussionMelastomataceae plastomes are no exception for the general patterns observed in the genomic structure of land plant chloroplasts, being highly conserved and structurally similar to most other Myrtales. Despite the fact that the full plastome phylogeny shares most of the clades with the previously widely used and reduced data set, some changes are still observed and bootstrap support is higher. The plastome data set presented here is a step towards phylogenomic analyses in the Melastomataceae and will be a useful resource for future studies.
