Premise of the Study We provide largest phylogenetic analyses to date Apocynaceae in terms taxa and molecular data as a framework for analyzing evolution vegetative reproductive traits. Methods produced maximum‐likelihood phylogenies using 21 plastid loci sampled from 1045 species (nearly 25% family) complete plastomes 73 species. reconstructed ancestral states used model comparisons likelihood analyze character across Apocynaceae. Key Results obtained well‐supported phylogeny Apocynaceae,...
Species of plants with different life history strategies may differ in their seed dispersal mechanisms, impacting distribution and diversification patterns. Shorter or longer distance is favored by modes, facilitating (or constraining) population isolation, which can, turn, impact speciation species range sizes. While these associations are intuitive, few studies have explicitly tested hypotheses for large clades angiosperms. The plant family Melastomataceae found on disparate habitats...
To elucidate deeper relationships within Rauvolfioideae (Apocynaceae), a phylogenetic analysis was conducted using sequences from five DNA regions of the chloroplast genome (matK, rbcL, rpl16 intron, rps16 and 3′ trnK intron), as well morphology. Bayesian parsimony analyses were performed on 50 taxa 16 Apocynoideae. Neither subfamily is monophyletic, because it grade Apocynoideae subfamilies Periplocoideae, Secamonoideae, Asclepiadoideae nest it. In addition, three nine currently recognized...

The extreme complexity of asclepiad flowers (Asclepiadoideae–Apocynaceae) has generated particular interest in the pollination biology this group plants especially mechanisms involved processes. This study compares two South American species, Morrenia odorata and brachystephana, with respect to morphology anatomy flower structures, dynamic aspects mechanism, diversity visitors effectiveness pollinators. Floral structure was studied fresh fixed following classical techniques. mechanism by...

The structure and organization of calycine colleters belonging to four genera Apocynaceae are described. Calycine were found in all species. All had the same histological composition, but morphological differences observed Most standard type, possible deviations resulted three types: bifurcated, laminar, sessile. Mechanisms cell separation, proliferation, elongation may explain origin new types. As a consequence changes, secretory surface was expanded sessile glands. post-secretory phase,...
The Neotropical tribe Mesechiteae (Apocynaceae) is currently considered to include nine genera: Allomarkgrafia, Galactophora, Macrosiphonia, Mandevilla, Mesechites, Quiotania, Secondatia, Telosiphonia, and Tintinnabularia. Tribal intergeneric relationships, however, are in dispute. To test the monophyly of evaluate intratribal a maximum parsimony analysis was conducted based on DNA sequences from plastid rpl16 intron, rps16 trnS-G intergenic spacer region as well morphological data for 23...
In order to test the monophyly of Mandevilla Lindl., largest genus in tribe Mesechiteae (Apocynaceae, Apocynoideae), and its affinities other genera tribe, maximum parsimony analysis was conducted on a data set comprising DNA sequences from five plastid loci (rpl16, rps16, trnK introns; trnSGCU-trnGUUC intergenic spacer; matK gene), as well morphological for 65 taxa (48, Mandevilla) nine tribes subfamily. Mandevilla, circumscribed by Pichon, found be monophyletic, whereas Woodson's...
Abstract Tabernaemontaneae (Rauvolfioideae, Apocynaceae) are small trees with mainly animal–dispersed fleshy fruits and arillate seeds represented in the tropics of Africa, Asia, Pacific America. The tribe is characterized by complex indole alkaloids, thus its species play a prominent role traditional medicine. Taxonomically, have convoluted history fraught contention as to tribal, subtribal, generic sectional delimitation, some authors recognizing Ambelanieae Macoubeeae separate tribes...
Abstract Vinceae comprises 9 genera and about 153 species. The differ greatly in a number of morphological traits, especially those relating to fruit seeds, which resulted their placement different tribes and/or subtribes by earlier taxonomists. Here, 378 new chloroplast DNA sequences from 98 species 5 the rauvolfioid grade were analyzed phylogenetically test monophyly Vinceae, its 6 subtribes, constituent genera, as well sectional treatments Rauvolfia , find synapomorphies for major clades....

Abstract The genus Zornia has a pantropical distribution and comprises 80 species in two subgenera ( Myriadena, ) three sections Zornia, Isophylla, Anisophylla ). is characterized mainly by flowers arranged spiciform inflorescence, with paired peltate bracteoles protecting each flower, stipules that resemble the bracteoles. Phylogenetically member of informal Adesmia clade Dalbergioid group, being most closely related to predominantly South American genera Poiretia Amicia . Phylogenetic...
The karyotype is shaped by different chromosome rearrangements during species evolution. However, determining which are responsible for changes a challenging task and the combination of robust phylogeny with refined characterization, GS measurements bioinformatic modelling necessary. Here, this approach was applied in Heterotaxis to determine what were dysploidy variation. We used two datasets (nrDNA cpDNA, both under MP BI) infer phylogenetic relationships among closely related genera...

Abstract The canga of the Serra dos Carajás, in Eastern Amazon, is home to a unique open plant community, harboring several endemic and rare species. Although complete flora survey has been recently published, scarce no genetic information available for most species ironstone outcrops Carajás. In this scenario, DNA barcoding appears as fast effective approach assess diversity Carajás flora, considering growing need robust biodiversity conservation planning such an area with industrial mining...
Historically, taxonomic delimitation of Mandevilla Lindley, a large Neotropical genus Apocynaceae, has been controversial. Two competing classifications were proposed by Woodson (1933) and Pichon (1948), the former now being widely accepted taxonomists in family. Recent phylogenetic studies, however, support monophyly sensu rather than Woodson, latter paraphyletic with respect to Quiotania Zarucchi, Macrosiphonia Müller Argoviensis, Telosiphonia (Woodson) Henrickson. Based on principle...
