“…Fiji and Tonga; see Tang, Xue, & Saunders, ), this indicates substantial potential for LDD across water bodies and subsequent establishment. Endozoochory seems the predominant dispersal mode in Goniothalamus , with fruits reportedly consumed by birds, and arboreal or ground‐dwelling mammals including primates, squirrels and rats (see Tang et al., and references therein). Avian dispersal vectors have the greatest potential to cross water barriers, although relatively short standard seed retention times need to be considered (e.g.…”

Aim The historical biogeography of the species‐rich flowering plant genus Goniothalamus (c. 130 species) and the wider Annonaceae tribe Annoneae is investigated to evaluate hypotheses regarding the processes underlying tropical intercontinental disjunctions (‘long‐distance dispersal [LDD]’ versus ‘boreotropics’) and floristic exchange between biodiversity hotspots in tropical Asia. Location Tropics, tropical Asia. Methods Divergence time estimation was based on plastid DNA sequence data (c. 10 kb; 164 Annonaceae accessions, including 65 Goniothalamus species) using an uncorrelated lognormal relaxed clock model and two fossil calibrations. Likelihood ancestral range estimation was performed using dispersal‐extinction‐cladogenesis models with and without time‐stratified dispersal constraints. Results The boreotropics model incorporating high chances for intercontinental dispersal during 68–34 Ma fitted the data significantly better than LDD models enforcing low intercontinental dispersal rates. Multiple vicariance events were identified in Annoneae including at the Annoneae crown node (57–49 Ma, Africa/S+N America), and the Disepalum‐Asimina split (27–24 Ma, Asia/N America). A wide ancestral range in continental SE Asia, W and E Malesia was inferred at the Goniothalamus crown node (24–21 Ma). Several dispersal events from continental SE Asia/W Malesia were identified in the Miocene: two north‐eastwards to the Philippines, one eastwards to the Sahul Shelf and two westwards to India. Main conclusions The boreotropics hypothesis provides a well‐supported, plausible explanation for the disjunctions and dispersal–vicariance patterns in tribe Annoneae. The wide distribution inferred at the Goniothalamus crown node indicates that its ancestors already bridged the marine gap between the Sunda and Sahul Shelves by LDD or rafting on tectonic plate microfragments. Dispersal across long‐standing water bodies in Malesia occurred multiple times from the early Miocene as marine gaps decreased following tectonic plate convergence and land emergence. Substantially older crown group divergence estimates compared with previous studies indicate that hypotheses of rapid recent radiation in Goniothalamus must be rejected.

“…Potentially, the addition of full chloroplast sequences or plastomes might provide some added resolution. Finally, it remains to be seen how much resolution and support we recover when reconstructing the phylogenetic relationships of species-rich genera such as Guatteria (Erkens et al, 2007;Maas et al, 2015) or Goniothalamus (Tang et al, 2015).…”

Targeted enrichment and sequencing of hundreds of nuclear loci for phylogenetic reconstruction is becoming an important tool for plant systematics and evolution. Annonaceae is a major pantropical plant family with 109 genera and ca. 2450 species, occurring across all major and minor tropical forests of the world. Baits were designed by sequencing the transcriptomes of five species from two of the largest Annonaceae subfamilies. Orthologous loci were identified. The resulting baiting kit was used to reconstruct phylogenetic relationships at two different levels using concatenated and gene tree approaches: a family wide Annonaceae analysis sampling 65 genera and a species level analysis of tribe Piptostigmateae sampling 29 species with multiple individuals per species. DNA extraction was undertaken mainly on silicagel dried leaves, with two samples from herbarium dried leaves. Our kit targets 469 exons (364 653 bp of sequence data), successfully capturing sequences from across Annonaceae. Silicagel dried and herbarium DNA worked eaually well. We present for the first time a nuclear gene-based phylogenetic tree at the generic level based on 317 supercontigs. Results mainly confirm previous chloroplast based studies. However, several new relationships are found and discussed. We show significant differences in branch lengths between the two large subfamilies Annonoideae and Malmeoideae. A new tribe, Annickieae, is erected containing a single African genus Annickia. We also reconstructed a well resolved species-level phylogenetic tree of the Piptostigmteae tribe. Our baiting kit is useful for reconstructing well supported phylogenetic relationships within Annonaceae at different taxonomic levels. The nuclear genome is mainly concordant with plastome information with a few exceptions. Moreover, we find that substitution rate heterogeneity between the two subfamilies is also found within the nuclear compartment, and not just plastomes and ribosomal DNA as previously shown. Our results have implications for understanding the biogeography, molecular dating and evolution of Annonaceae.

“…Different palynological and morphological studies have been conducted in the Annonaceae (Doyle & Le Thomas, , ) which have been highly informative for classifying the different groups in this family (Doyle & Le Thomas, ). More recently, molecular phylogenetic studies mainly using plastid regions ( rbcL, matK, ndhF, trnL, trnT‐L, trnL‐F, trnS‐G, atpB‐rbcL, trnH‐psbA, ycf1, rpl32‐trnL, or ndhF‐rpl32 ) have provided valuable information on specific and general aspects of the Annonaceae (Mols et al, ; Richardson et al, ; Pirie et al, ; Chatrou et al, ; Erkens et al, ; Thomas et al, ; Chaowasku et al, ; Larranaga & Hormaza, ; Tang et al, ; Guo et al, ; Hoekstra et al, ). Annona , described by Linnaeus () and further clarified by Safford (), includes approximately 162 species (Chatrou et al, ), distributed mainly in the Neotropics, with a few species native to Africa.…”

Annona cherimola is a woody perennial species in the Annonaceae family that produces edible fruits and has economic importance in several regions of the world with subtropical climates. Together with other 10‐12 species, A. cherimola belongs to the section Atta of the Annona genus with a center of origin in Central America and the Caribbean. Species of the section Atta produce soft skin ripe fruits with raised areoles bounded by recessed furrows. Annona cherimola is the only species of the section naturally found in the Andean region of South America. Currently, no information is available at the molecular level on the phylogenetic relationships of most of the species of Atta and closely related sections in Annona. In order to fill this gap, in this work a phylogenetic approach was performed using five coding and non‐coding plastid DNA regions, to determine the phylogenetic relationships between A. cherimola and other related species included in Atta and other sections of the genus. The results obtained support recent studies that demonstrated the likely Mesoamerican origin of A. cherimola based on biogeographical analysis with SSR markers, rather than the previously considered South American origin hypothesis. In addition, the species belonging to the Atta section did not show monophyly. Finally, A. cherimola and A. pruinosa seem to be phylogenetically close species and additional studies are needed to discern the relations between them.
