“…In summary, our data indicate that intronic regions of nuclear genes isi1 and nhx1 are candidate markers for comparative studies in cacti, in concordance with previous data (Franck et al, 2012, 2013). The plastid segments trnQ (UUG) -5′rps16 , rpL16 , and trnS-trnG showed higher levels of variability among the cpDNA markers tested at the population level for Cereus , becoming candidate markers for further phylogeographic studies in this genus, which is broadly distributed in South America.…”

“…We selected 16 plastid segments to collect empirical data, including those more likely to be variable as proposed by Shaw et al (2005, 2007, 2014): rpS16 , rpL16 , trnL-trnF , trnT-trnL , 3′trnK-matK partial, 3′rps16–5′trnK (UUU) , trnS-trnG , trnH-psbA , trnQ (UUG) -5′rps16 , rpl32-trnL (UAG) , psbJ-petA , atpI-atpH , petL-psbE , psbD-trnT (GGU) , 3′trnV (UAC) -ndhC , and ndhF-rpl32 . Furthermore, we included in our screening intronic regions of two nuclear genes: the impaired sucrose induction gene ( isi1 ; Rook et al, 2006) and the Na + /H + vacuolar antiporter gene ( nhx1 ; Gaxiola et al, 1999), because these genes have been used successfully in comparative studies within Cactaceae (Franck et al, 2012, 2013). With this approach, we were able to identify regions suitable for intra- and interspecific studies in Cereus .…”

Lineage‐specific evolutionary rate in plants: Contributions of a screening for Cereus (Cactaceae)

et al. 2016

Premise of the study:Predictable chloroplast DNA (cpDNA) sequences have been listed for the shallowest taxonomic studies in plants. We investigated whether plastid regions that vary between closely allied species could be applied for intraspecific studies and compared the variation of these plastid segments with two nuclear regions.Methods:We screened 16 plastid and two nuclear intronic regions for species of the genus Cereus (Cactaceae) at three hierarchical levels (species from different clades, species of the same clade, and allopatric populations).Results:Ten plastid regions presented interspecific variation, and six of them showed variation at the intraspecific level. The two nuclear regions showed both inter- and intraspecific variation, and in general they showed higher levels of variability in almost all hierarchical levels than the plastid segments.Discussion:Our data suggest no correspondence between variation of plastid regions at the interspecific and intraspecific level, probably due to lineage-specific variation in cpDNA, which appears to have less effect in nuclear data. Despite the heterogeneity in evolutionary rates of cpDNA, we highlight three plastid segments that may be considered in initial screenings in plant phylogeographic studies.

“…15–11 Ma), after a global drop in temperatures led to the expansion of arid and semi‐arid habitats worldwide (Arakaki et al., ; Hernández‐Hernández, Brown, Schlumpberger, Eguiarte, & Magallón, ). Although there are still few generic studies in cacti (Franck, Cochrane, & Garey, ; Franco et al., ; Majure et al., ; Silva, Antonelli, Lendel, Moraes, & Manfrin, ), estimates from these, and more inclusive family‐level phylogenies (Arakaki et al., ; Hernández‐Hernández et al., ), indicate an age of origin of many genera around the Pliocene–Pleistocene transition (2.58 Ma, http://www.stratigraphy.org), with species divergences dated well within the Pleistocene (Bonatelli et al., ; Franco et al., ; Silva et al., ). These studies suggest that events of rapid climate change since the Paleogene have been important drivers in the evolution of cacti.…”

Aim Pilosocereus is one of the richest and most widespread genera of columnar cacti, extending from south‐west USA to southern Brazil. Most species occur in the seasonally dry tropical forest biome but can also be found in xeric microhabitats inside woody savannas (Cerrado) and moist forests (Brazilian Atlantic forest). The genus exhibits a highly disjunct distribution across the Neotropics. Using a 90% complete species‐level phylogeny, we reconstructed the spatio‐temporal evolution of Pilosocereus to explore the historical factors behind the species richness of Neotropical dry formations. Location South America, Mesoamerica, Caribbean, south‐western North America. Taxon Genus Pilosocereus (Cactaceae, Cactoideae, Cereeae). Methods We used plastid and nuclear DNA sequences and Bayesian inference to estimate phylogenetic relationships and lineage divergence times. Ancestral ranges were inferred within the Pilosocereus subgenus Pilosocereus s. s. clade using the Dispersal–Extinction–Cladogenesis model in a Bayesian framework to account for parameter estimation uncertainty and the effect of geographical distance on dispersal rates. Results Pilosocereus was recovered as polyphyletic, with representatives of other Cereeae nested within. The Pilosocereus subgenus Pilosocereus s. s. clade originated around the Pliocene–Pleistocene transition (2.7 Ma), probably within the Caatinga seasonally dry tropical forest (SDTF) formation. Species divergences were dated in the Middle and Upper Pleistocene, often constrained to the same geographic region but also associated to migration events to other xeric habitats in Mesoamerica and northern South America; dispersal rates were not dependent on distance. Main conclusions Diversification dynamics in the Pilosocereus subgenus Pilosocereus s. s. clade agree with other infrageneric studies in cacti. Species divergence was rapid, driven by in situ diversification and migration events between SDTF dry formations and xeric microhabitats within other biomes and probably linked to Pleistocene climatic changes. This dynamic history differs from that found in woody SDTF lineages, which are older in age and characterized by low‐dispersal rates and long‐term isolation.

Previous taxonomic schemes for the Cylindropuntieae were re-evaluated in the light of a molecular phylogeny derived from a Bayesian, maximum-likelihood and parsimony reconstructions with three plastid regions (atpB-rbcL, psbA-trnH and trnK/matK data sets). The reconstruction revealed that Corynopuntia and Grusonia as currently defined were polyphyletic. Quiabentia, Micropuntia, Pereskiopsis and Cylindropuntia were the only genera recovered as monophyletic. Grusonia s.s. (only including G. bradtiana) is nested in a polytomy with the rest of the species of Corynopuntia. Grusonia s.l. (G. bradtiana plus Corynopuntia) and Corynopuntia as currently defined are polyphyletic because G. pulchella is sister to Pereskiopsis. Some previous taxonomic proposals for Cylindropuntia and Grusonia recognized polyphyletic series and subgenera that do not conform to the strongly supported monophyletic groups here recovered. This study proposes redefining the polyphyletic Grusonia excluding G. pulchella in order to recognize a strongly supported monophyletic genus and the acceptance of a monotypic Micropuntia (G. pulchella) avoiding a new combination into Pereskiopsis. The infrageneric classification for Grusonia is discussed and the recognition of only four monophyletic strongly supported series (Bigelovianae, Imbricatae, Leptocaules and Ramosissimae) for Cylindropuntia is presented.
