“…Clade 3 had the same maternal ancestor as Clade 4 and the same paternal ancestor as Clade 1, indicating hybrid origin of the whole Clade 3 and making it an interesting example for the reticulate origin of a major lineage in grasses. Comparable instances of deep reticulation were recently documented also in other angiosperm families and orders (García & al., 2014(García & al., , 2017Sun & al., 2015;Bruun-Lund & al., 2017;Knowles & al., 2018;Herrando-Moraira & al., 2019).…”

To investigate the evolutionary diversification and morphological evolution of grass supertribe Poodae (subfam. Pooideae, Poaceae) we conducted a comprehensive molecular phylogenetic analysis including representatives from most of its accepted genera. We focused on generating a DNA sequence dataset of plastid matK gene-3′trnK exon and trnL-trnF regions and nuclear ribosomal (nr) ITS1-5.8S gene-ITS2 and ETS that was taxonomically overlapping as completely as possible (altogether 257 species). The idea was to infer whether phylogenetic trees or certain clades based on plastid and nrDNA data correspond with each other or discord, revealing signatures of past hybridization. The datasets were analysed separately, in combination, by excluding taxa with discordant placements in the individual gene trees and with duplication of these taxa in a way that each duplicate has only one data partition (plastid or nrDNA). We used maximum likelihood, maximum parsimony and Bayesian approaches. Instances of severe conflicts between the phylogenetic trees derived from both datasets, some of which have been noted earlier, point to hybrid origin of several lineages such as the ABCV clade encompassing several subtribes and subordinate clades,

“…These subgenera were not recognized as monophyletic based on the phylogeny of nuclear genes (Xu & al., 2011; Cruaud & al., 2012; Pederneiras & al., 2018). Furthermore, none of the six subgenera could be characterized as monophyletic when assessed by chloroplast phylogenomic analysis (Bruun‐Lund & al., 2017).…”

Phylogenetic reconstruction of Ficus subg. Synoecia and its allies (Moraceae), with implications on the origin of the climbing habit

The infrageneric classification of Ficus (Moraceae) has raised concerns since Berg put forward his six subgenera system. Molecular analyses have revealed some unnatural groups within this system. The status of F. subg. Synoecia and the relationships between this subgenus and its allies are among the major challenges facing classification within the genus. To resolve these problems, we reconstructed the phylogenetic trees with three nuclear markers from 147 ingroup taxa (including approximately half of F. subg. Synoecia species and three‐fifths of F. subg. Ficus) and implemented ancestral area and life‐form reconstructions to trace the evolutionary history. Results showed that F. subg. Synoecia and F. subg. Ficus (except F. subsect. Ficus) constituted a well‐supported monophylum, which is sister to F. subg. Terega. This monophylum comprises two clades: one clade covers F. subsect. Frutescentiae of F. sect. Ficus and F. subsect. Plagiostigma of F. sect. Pogonotrophe, and the other covers F. sect. Eriosycea, F. sect. Apiosycea and the rest of F. sect. Pogonotrophe. Ancestral area reconstruction revealed that the first clade has a distinct origin in East Asia, but the second one shows fewer obvious signs. Ancestral life‐form reconstruction suggested that the climbing habit, a key trait used to divide F. subg. Ficus and F. subg. Synoecia, has evolved independently more than four times, rendering it an unsuitable characteristic to circumscribe the subgenera. Thus, we merged F. subg. Synoecia and F. subg. Ficus (excluding F. subsect. Ficus) into one subgenus, containing two newly delimited sections and six new synonyms.

“…Our hypothesis is that the nuclear evidence, here represented by ITS/5.8S and ETS, groups Acca , Psidium , and Myrrhinium , a grouping that is in conflict with at least part of the plastid evidence, that places Acca elsewhere. A nuclear-plastid conflict has been reported in the family Myrtaceae (Schuster et al, 2018) and in other large groups (e.g., in Ficus ; Bruun-Lund et al, 2017). In our balance of evidence, we accept the result using our concatenated matrix and study the morphological characters on that topology (see below).…”

Evolution of pollination by frugivorous birds in Neotropical Myrtaceae

Bird pollination is relatively common in the tropics, and especially in the Americas. In the predominantly Neotropical tribe Myrteae (Myrtaceae), species of two genera, Acca and Myrrhinium, offer fleshy, sugary petals to the consumption of birds that otherwise eat fruits, thus pollinating the plants in an unusual plant-animal interaction. The phylogenetic position of these genera has been problematic, and therefore, so was the understanding of the evolution of this interaction. Here we include new sequences of Myrrhinium atropurpureum in a comprehensive molecular phylogeny based on a balanced sample of two plastid and two nuclear markers, with the aim of providing the historical framework of pollination by frugivorous birds in Myrteae. We developed 13 flower and inflorescence characters that comprehensively depict the macroscopic morphological components of this interaction. Bayesian and parsimony phylogenies concur in placing both Acca and Myrrhinium in a clade with Psidium species; with Myrrhinium sister to Psidium. Mapping of morphological characters indicated some degree of convergence (e.g., fleshy petals, purplish display) but also considerable divergence in key characters that point to rather opposing pollination strategies and also different degrees of specialization in Acca versus Myrrhinium. Pollination by frugivorous birds represents a special case of mutualism that highlights the evolutionary complexities of plant-animal interactions.
