Data from: No evidence for Fabaceae Gametophytic self-incompatibility being determined by Rosaceae, Solanaceae, and Plantaginaceae S-RNase lineage genes
Background: Fabaceae species are important in agronomy and livestock nourishment. They have a long breeding history, and most cultivars have lost self-incompatibility (SI), a genetic barrier to self-fertilization. Nevertheless, to improve legume crop breeding, crosses with wild SI relatives of the cultivated varieties are often performed. Therefore, it is fundamental to characterize Fabaceae SI system(s). We address the hypothesis of Fabaceae gametophytic (G)SI being RNase based, by recruiting the same S-RNase lineage gene of Rosaceae, Solanaceae or Plantaginaceae SI species. Results: To address if Fabaceae GSI is RNase based we first looked for the presence of SSK1 like genes (described only in species having RNase based GSI), in the Trifolium pratense, Medicago truncatula, Cicer arietinum, Glycine max, and Lupinus angustifolius genomes. Since we find these genes in Fabaceae species, we characterize the S-lineage T2-RNase genes in these genomes. Except for T. pratense, all species are self-compatible (SC). Nevertheless, in T. pratense, but also in M. truncatula and C. arietinum we identify S-RNase lineage genes that in phylogenetic analyses cluster with Pyrinae S-RNases. In M. truncatula and C. arietinum genomes, where large scaffolds are available, these sequences are surrounded by F-box genes that in phylogenetic analyses also cluster with S-pollen genes. In T. pratense the S-RNase lineage genes show, however, expression in tissues not involved in GSI. Moreover, levels of diversity are lower than those observed for other S-RNase genes. The M. truncatula and C. arietinum S-RNase and S-pollen like genes phylogenetically related to Pyrinae S-genes, are also expressed in tissues other than those involved in GSI. To address if other T2-RNases could be determining Fabaceae GSI, here we obtained a style with stigma transcriptome of Cytisus striatus, a species that shows significant difference on the percentage of pollen growth in self and cross-pollinations. Expression and polymorphism analyses of the C. striatus S-RNase like genes revealed that none of these genes, is the S-pistil gene. Conclusion: We find no evidence for Fabaceae GSI being determined by Rosaceae, Solanaceae, and Plantaginaceae S-RNase lineage genes. Since none of the C. striatus T2-RNase genes expressed in style with stigma is involved in GSI specificity, there is no evidence that T2-RNase lineage genes could be determining GSI in this species. Therefore, to characterize the Fabaceae S-pistil gene(s), expression analyses, levels of diversity, and segregation analyses in controlled crosses are needed for those genes showing high expression levels in the tissues where GSI occurs.
Data from: Analyzing reticulate relationships using CpDNA and pyrosequenced ITS1 as exemplified by Veronica subgen. Pseudolysimachium (Plantaginaceae)
Veronica subgen. Pseudolysimachium constitutes a group of about 28 species across northern Eurasia, many of them with considerable intraspecific morphological variation. This intraspecific variation may be due to large geographical distribution area, wide ecological amplitude, or widespread hybridization and polyploidization. Several recent studies using molecular data have shown that hybridization as an explanation for generating evolutionary novelties and high intraspecific variation may be more common than previously thought. Here we investigate the importance of hybridization in generating morphological variation and blurring species boundaries in V. subgen. Pseudolysimachium using analyses of cpDNA sequences from 139 individuals from 18 species and ten putative hybrids, and pyrosequenced ITS1 nrDNA sequences from 37 individuals from 16 species and four putative hybrids. In addition, we estimated ploidy levels for 42 individuals of ten species and five putative hybrids using flow cytometry. Analyses of cpDNA did not resolve phylogenetic structure (most of the species were polyphyletic). Our second approach, pyrosequencing of ITS1, generated up to nine different unique sequences per individual and phylogenetic analyses of the dataset resolved some basal nodes but, again, species were often non-monophyletic. The results are most compatible with a scenario of an East Asian origin and repeated spread across Pleistocene Eurasian steppes, known as important plant diversification center, with frequent interspecific hybridization. We compare the applicability of these molecular regions for resolving hybridizing species complexes and specifically address hypotheses of hybrid origins for several species within the subgenus. However, any population genetic, phylogeographic or other analysis of evolutionary questions in one species alone would be futile without considering introgression from related species.
Data from: Phylogenetic relationships and morphological evolution in the carnivorous genus Philcoxia (Plantaginaceae, Gratioleae)
Philcoxia (Plantaginaceae, Gratioleae) is a genus with seven species of small herbs endemic to Brazil. It is characterized by underground stems and petioles, peltate leaves, and zigzag racemose inflorescences, in addition to a remarkable carnivorous syndrome. The phylogenetic placement of Philcoxia within tribe Gratioleae has been uncertain since its discovery due to its unique morphology and limited data from phylogenetic studies. We tested the phylogenetic placement of Philcoxia within Gratioleae, increasing the number of species sampled within both the genus and the rest of the tribe, and sequencing four regions from cpDNA (rpl16, rps16, and trnL introns and the trnL-trnF intergenic spacer) and one from nrDNA (ITS1 spacer); we used both parsimony and Bayesian inference to reconstruct the phylogeny. Moreover, we assessed both the monophyly of the genus and interspecific relationships. Finally, we performed ancestral character state reconstructions of 10 morphological characters to infer synapomorphies for the genus and specific clades within it. Philcoxia was recovered as monophyletic, with maximum support values, as sister to Stemodia stellata. Five morphological character states were reconstructed as potential synapomorphies for the Philcoxia clade (rosetted herb habit, underground stems and petioles, floral resupination, number of stamens reduced to two, and number of fertile thecae per anther reduced to one), whereas fourwere reconstructed as potential synapomorphies for specific clades within the genus (peltate leaves, irregular rosettes, vegetative propagation by rhizomes, and presence of tubers). Further anatomical studies, in association with ecological data, would provide insight into the structure of the underground systems and its adaptive significance, and would further elucidate the evolution of carnivory in Philcoxia. Our study highlights the need to reassess the concepts and circumscriptions of some currently accepted genera of the Gratioleae such as Bacopa, Conobea, and Stemodia, and for the tribe Angelonieae.

Characterization of the complete chloroplast genome of the medicinal herb Veronica polita Fr. (Lamiales: Plantaginaceae)
<p><em>Veronica polita</em> Fr. (synonym: <em>Veronica didyma</em> Ten.), an annual herbaceous species with high medicinal values, is originally from Southwest Asia but has been naturalized widely in many regions of the world. In this study, the complete chloroplast genome of <em>V. polita</em> was determined to be 150,191 bp long with a typical quadripartite structure. It encodes a panel of 114 genes with 18 of them being completely or partially duplicated and 19 of them possessing one or two introns. The phylogenetic analysis appeared to support the tribal-level taxonomy of the family Plantaginaceae, and revealed that <em>V. polita</em> was most closely related to the congener <em>V. persica</em>.</p>
