“…Species and populations of trees with vast geographic ranges, outcrossing breeding systems, and seed distribution by animals or wind show higher genetic diversity than species with other combinations of traits [38]. Anadenanthera colubrina and A. peregrina are mixed-mating reproductive species with barochoric seed dispersal, with A. peregrina preferentially allogamous [12]. Its potential pollinators are Apidae bees Apis mellifera, and native Trigona spinipes [39].…”

“…Anadenanthera colubrina and A. peregrina are dominant trees that occur naturally in the Brazilian deciduous and Cerrado forests of Ribeirão Preto and other parts of Brazil and South America [4][5][6][7]11,12,43,44]. These species show resilience in the face of fragmentation, surviving in areas unsuitable for agriculture due to their reproductive characteristics and apparent ease of seed germination and seedling establishment [7,45,46].…”

“…Recently, molecular studies with chloroplast simple sequence repeats (cpSSRs) [11], chloroplast DNA (cpDNA) [12], nuclear microsatellite (nSSR) [6,[13][14][15], and the Internal Transcribed Spacer region of the rDNA (ITS-rDNA) [16] have been published related to genetic diversity [14], ex situ conservation [13], evolution [11,12,15], and mating systems [6] for Anadenanthera species. However, there has been no genetic study with inter-simple sequence repeat (ISSR) markers in Anadenanthera that may aid in taxonomic distinguishing of species [17].…”

Anadenanthera colubrina (Acol) and Anadenanthera peregrina (Aper) (Fabaceae) are two species popularly known as “angicos” that occur in seasonally dry tropical forest (SDTR) remnants in Brazil. Since many of the morphological characteristics of Anadenanthera species are superimposed and species-specific characteristics are difficult to observe, their identification is complex. Therefore, in this research, a set of ISSR (Inter-Simple Sequence Repeat Polymorphic DNA) molecular markers was standardized, aiming to characterize A. colubrina and A. peregrina species and study the genetic diversity of three populations of each species located within a fragmented landscape in São Paulo State, southeastern Brazil. Seven ISSR markers (UBC 2, 820, 851, 858, 864, 866, and 886) that show polymorphism for both species were used. The Bayesian cluster, PCoA and dendrogram analysis show that the total sample divides into two groups corresponding to each species. Also, a genetic divergence (Gst = 0.143) and a high number of migrants per generation (Nm = 3.0) were detected between them. The Acol populations showed significantly higher values for mean genetic diversity (h = 0.30) than Aper (h = 0.25) (p < 0.05). The ISSR marker UBC2250bp showed species-specific electrophoretic fingerprints for both species. The molecular tools generated herein support the conservation of Anadenanthera sp. and the restoration of vegetation where the species naturally occurs.

The understanding of genetic diversity and evolutionary relationships within the genus Anadenanthera Speg. (Fabaceae) is limited. Brenan’s classification recognized four species, but Altschul’s classification currently recognizes only two species, each with two varieties. Both classifications were based solely on morphology. We analysed molecular data from 283 specimens using 12 SSRs and 186 specimens using ITS sequence data. The results showed that neither SSR-based genotyping nor ITS-based phylogeny supported Altschul’s classification. Instead, they provided evidence of four reproductively isolated taxa and a single clade corresponding to one of Altschul’s varieties. Additionally, ecological niche modelling (ENM) investigated the influence of past climate on the geographic distribution of Anadenanthera. The ENM results suggest that the ‘varieties’ may have occupied different regions of South America with distinct paleoclimates. On the basis of these findings, the authors suggest recognizing four species, as per Brenan’s original classification.

Unravelling the evolutionary history and promoting conservation genetics of Anadenanthera colubrina var. cebil (Leguminosae), a paradigmatic species in Seasonally Dry Tropical Forests

Seasonally Dry Tropical Forests (SDTFs) exhibit a patchy distribution throughout the Neotropics and are considered one of the most threatened tropical forests in the world. Nonetheless, their conservation has often been neglected in comparison to efforts directed towards other biomes. The distribution pattern of Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb) Altschul allows an adequate mapping of this biome. The main objectives of this work are to study the historical processes that determined the current distribution of A. colubrina var. cebil under the hypothesis that the demographic history of the remaining fragments of SDTFs in Argentina leads back to a single event of ancestral divergence, and identify Argentinean localities with priority for conservation. Plastid genetic diversity of A. colubrina var. cebil from northern Argentina is characterised using three plastid microsatellite loci. From this, genetic characterization, population genetics, and Bayesian inference were carried out. The results from approximate Bayesian computations show that the Misiones and Piedmont Subandean nuclei diverged from an ancestral population in the early Neogene while the Formosa population derived from the Misiones nucleus in the late Neogene. Two out of five locations from the Misiones nucleus and three of nine locations from the Subandean Piedmont nucleus are proposed as priority conservation areas.
