A major goal of phylogenetic systematics is to understand both the patterns diversification and processes by which these are formed. Few studies have focused on ancient, species-rich Magnoliales clade its pattern. Within Magnoliales, pantropically distributed Annonaceae far most genus-rich family-level clade, with c. 110 genera 2,400 species. We investigated across identified traits that show varied associations rates using a time-calibrated phylogeny 835 species (34.6% sampling) 11,211 aligned bases from eight regions plastid genome (rbcL, matK, ndhF, psbA-trnH, trnL-F, atpB-rbcL, trnS-G, ycf1). Twelve rate shifts were BAMM: in Annona, Artabotrys, Asimina, Drepananthus, Duguetia, Goniothalamus, Guatteria, Uvaria, Xylopia, tribes Miliuseae Malmeeae, Desmos-Dasymaschalon-Friesodielsia-Monanthotaxis clade. TurboMEDUSA method-of-moments estimator analyses showed largely congruent results. positive relationship between richness revealed PGLS.

Monodoreae (Annonaceae) is a tribe composed of 11 genera and 90 species restricted to the tropical African rain forests. All are taxonomically well circumscribed except rich Uvariodendron Uvariopsis which lack recent taxonomic revision. Here, we used robust phylogenomic approach, including all currently accepted species, with several specimens per based on more than 300 Annonaceae-specific nuclear genes, infer phylogenetic tree test limits between species. We recover as monophyletic, genus for Uvariopsistripetala falls outside this clade. thus reinstate monotypic Dennettia its single Dennettiatripetala. also erect new tribe, Ophrypetaleae trib. nov., accommodate Ophrypetalum Sanrafaelia, them excluded from good support.

Comparative analysis of plastid genomes reveals rearrangements, repetitive sequence features, and phylogeny in the Annonaceae

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: April 17, 2024

The Annonaceae stands as the most species rich family in Magnoliales, a basal group of angiosperms. Widely distributed tropical and subtropical regions, it holds significant ecological economic value. plastid genome (plastome) is often employed studies related to plant phylogenetics, comparative genomics, evolutionary biology, genetic engineering. Nonetheless, research progress on genomics has been relatively slow. In this study, we analyzed structure repetitive sequence features plastomes from 28 species. Among them,

Abstract Sapranthus (Annonaceae) is a Neotropical genus comprising ten small tree species, most of which inhabit the tropical dry forests Mexico and Central America. Morphological characteristics these species are quite variable taxonomically informative, but morphological affinities among them have not been studied. A multivariate cluster analysis was carried out to infer all , establish position new S. pinedai shade used in coffee plantations Guatemala El Salvador. This illustrated described herein, recognized by unique combination features identified through comparisons with morphologically similar taxa, preliminary assessment conservation status calculated. The results presented here show that forms four groupings two main clusters. more microcarpus campechianus differs from both its essentially glabrous leaves, short pedicels, fewer carpels, greater number ovules per carpel, biseriate ovules, larger sessile fruits thick testa, several lunate wedge-shaped seeds. These provides insights into understanding sectional classification geographic distribution affinity species.

The topographical, geological, climatic and biodiversity complexity of Mesoamerica has made it a primary research focus. Mesoamerican highlands is region with particularly high species richness within-species variation. Cinnamon-bellied Flowerpiercer, Diglossa baritula (Wagler, 1832), endemic to the highlands, three allopatric subspecies currently recognized. To characterize divergence within this species, we integrated genomics, morphology, coloration ecological niche modeling approaches, obtained from sampling individuals across entire geographic distribution species. Our results revealed clear genomic between populations east versus west Isthmus Tehuantepec. In contrast results, morphology analyses showed intermediate levels differentiation, indicating that population groups D. have probably been under similar selective pressures. indicated only sexually dimorphic morphological variable wing chord, males having longer chord than females.
