“…However, some problems limit its use in phylogenetic studies, such as frequent indels, microsatellites, inversions, a high degree of homoplasy, and the presence of inversions in the middle of the sequence, which can lead to incorrect alignments; however, psbA-trnH may still be a successful marker due to its high interspecific variability (Korotkova et al, 2011). Korotkova et al (2011) stated that the psbA-trnH spacer is the most successful individual region for operational taxonomic unit identification at the intraspecific level, and the intergenic spacer trnL-trnF has been the most frequently used locus in phylogenetic studies of the Opuntioideae (Griffith and Porter, 2009;Hernández-Hernández et al, 2011;Majure et al, 2012b). ppc and ycf1 have been sequenced in the Opuntieae tribe, and are moderately informative Majure et al, 2012b).…”

“…It has traditionally been recognized as a monophyletic taxonomic entity (Griffith and Porter, 2009;Hernández-Hernández et al, 2011). It is characterized by a number of synapomorphies: 1) the presence of glochids (small and deciduous barbed spines); 2) woody funicular tissue surrounding the seed (funicular envelope); 3) large numbers of calcium oxalate monohydrate druses and monoclinic cluster crystals in the outer hypodermis of stems; and 4) polyporate pollen grains with peculiar exine structures (Hunt, 2006).…”

“…Molecular phylogenetic studies have demonstrated that Opuntia s.l. is polyphyletic (Griffith and Porter, 2009). Therefore, Opuntia sensu stricto (s.s.) has been drastically reduced in size, with many segregate genera now recognized [e.g., Austrocylindropuntia Backeb., Brasiliopuntia (K.…”

“…A. Berger, Cylindropuntia (Engelm.) F. M. Knuth] (Hunt, 2006;Griffith and Porter, 2009). Opuntia s.s. (nopal and prickly pears) is the largest genus in the Opuntioideae, and may have originated as recently as 5.6 (± 1.9) million years ago (Arakaki et al, 2011).…”

“…Griffith and Porter (2009) included 28 species of Opuntia s.s. in their molecular phylogeny of the Opuntioideae, but were unable to resolve relationships within Opuntia s.s. using nuclear internal transcribed spacers (ITSs) and the plastid intergenic spacer trnL-F. Hernández-Hernández et al (2011) and Bárcenas et al (2011) studied phylogenetic relationships between South American Opuntia species, but only surveyed seven species and had no resolution between clades, respectively. The most complete phylogeny available for the subfamily Opuntioideae is that of Griffith and Porter (2009). They sampled 110 specimens using ITSs and the chloroplast trnL-trnF regions.…”

ABSTRACT. Molecular methods are powerful tools in characterizing and determining relationships between plants. The aim of this study was to study genetic divergence between 103 accessions of Mexican Opuntia. To accomplish this, polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis of three chloroplast intergenic spacers (atpB-rbcL, trnL-trnF, and psbA-trnH), one chloroplast gene (ycf1), two nuclear genes (ppc and PhyC), and one mitochondrial gene (cox3) was conducted. The amplified products from all the samples had very similar molecular sizes, and there were only very small differences between the undigested PCR amplicons for all regions, with the exception of ppc. We obtained 5850 bp from the seven regions, and 136 fragments were detected with eight enzymes, 37 of which (27.2%) were polymorphic. We found that 40% of the fragments from the chloroplast regions were polymorphic, 9.8% of the bands detected in the nuclear genes were polymorphic, and 20% of the bands in the mitochondrial locus were polymorphic. trnL-trnF and psbA-trnH were the most variable regions. The Nei and Li/Dice distance was very short, and ranged from 0 to 0.12; indeed, 77 of the 103 genotypes had the same genetic profile. All the xoconostle accessions (acidic fruits) were grouped together without being separated from three genotypes of prickly pear (sweet fruits). We assume that the genetic divergence between prickly pears and xoconostles is very low, and question the number of Opuntia species currently considered in Mexico.

Premise Although numerous phylogenetic studies have been conducted in Cactaceae, whole‐plastome datasets have not been employed. We used the chollas to develop a plastome dataset for phylogeny reconstruction to test species relationships, biogeography, clade age, and morphological evolution. Methods We developed a plastome dataset for most known diploid members of the chollas (42 taxa) as well as for other members of Cylindropuntieae. Paired‐end, raw reads from genome skimming were reference‐mapped onto a de novo plastome assembly of one species of cholla, Cylindropuntia bigelovii, and were used to build our plastome dataset, which was analyzed using various methods. Results Our plastome dataset resolved the phylogeny of the chollas, including most interspecific and intraspecific relationships. Tribe Cylindropuntieae arose ~18 mya, during the early Miocene in southern South America, and is supported as sister to the South American clade Tephrocacteae. The (Micropuntia (Cylindropuntia + Grusonia)) clade most likely originated in the Chihuahuan Desert region around 16 mya and then migrated into other North American desert regions. Key morphological characters for recognizing traditional taxonomic series in Cylindropuntia (e.g., spiny fruit) are mostly homoplasious. Conclusions This study provides the first comprehensive plastome phylogeny for any clade within Cactaceae. Although the chollas s.l. are widespread throughout western North American deserts, their most recent common ancestor likely arose in the Chihuahuan Desert region during the mid‐Miocene, with much of their species diversity arising in the early to mid‐Pliocene, a pattern strikingly similar to those found in other western North American desert groups.

Premise The Caribbean islands are in the top five biodiversity hotspots on the planet; however, the biogeographic history of the seasonally dry tropical forest (SDTF) there is poorly studied. Consolea consists of nine species of dioecious, hummingbird‐pollinated tree cacti endemic to the West Indies, which form a conspicuous element of the SDTF. Several species are threatened by anthropogenic disturbance, disease, sea‐level rise, and invasive species and are of conservation concern. However, no comprehensive phylogeny yet exists for the clade. Methods We reconstructed the phylogeny of Consolea, sampling all species using plastomic data to determine relationships, understand the evolution of key morphological characters, and test their biogeographic history. We estimated divergence times to determine the role climate change may have played in shaping the current diversity of the clade. Results Consolea appears to have evolved very recently during the latter part of the Pleistocene on Cuba/Hispaniola likely from a South American ancestor and, from there, moved into the Bahamas, Jamaica, Puerto Rico, Florida, and the Lesser Antilles. The tree growth form is a synapomorphy of Consolea and likely aided in the establishment and diversification of the clade. Conclusions Pleistocene aridification associated with glaciation likely played a role in shaping the current diversity of Consolea, and insular gigantism may have been a key innovation leading to the success of these species to invade the often‐dense SDTF. This in‐situ Caribbean radiation provides a window into the generation of species diversity and the complexity of the SDTF community within the Antilles.
