Almonds and peaches are among the most economically important fruit crops in subtropical and temperate regions. [] Key Method Amygdalus were included in phylogenetic analyses of plastid ndhF-rpl32, rpL16, trnH-psbA, trnL-trnF, trnQ-5′rps16, and trnS-trnG and nuclear s6pdh genes to investigate the circumscription of subg. Amygdalus, phylogenetic relationships among the species, and implication for mesocarp and endocarp evolution. Prunus subg. Amygdalus is best circumscribed to include both almonds and peaches…
Molecular phylogeny of the genus Amygdalus (Rosaceae) based on nrDNA ITS and cpDNA trnS-trnG sequences
Phylogenetic relationships of the Iranian wild almonds based on data from 2 nuclear and chloroplast spacers and NeighborNet analysis of the nrDNA ITS dataset of Iranian almonds supported reticulate relationships for all Amygdalus hybrids as previously reported.
Study on Phylogenetic Relationship among some of Iranian Wild Almond Species using Sequences of ITS1-5.8S rDNA-ITS2 Region and Chloroplastic trnL
Phylogenetic relations among 12 wild species of almonds, one cultivated almond and one species of peach were investigated by using of ITS1-5.8S rDNA-ITS2 sequences and trnL region of chloroplast DNA and it can be reported that Prunus is monophyletic.
Combining conservative and variable markers to infer the evolutionary history of Prunus subgen. Amygdalus s.l. under domestication
The phylogenetic analysis with both sequence and SSR loci confirms the split between sections Amygdalus and Persica, comprising almonds and peaches, respectively, in agreement with biogeographic data showing that each of the two sections is naturally distributed on each side of the Central Asian Massif chain.
Some nomenclatural adjustments and typifications for almond species in the genus Prunus sensu lato (Rosaceae)
Twenty-two new combinations, one nomen novum, and one new nothospecies are proposed for Prunus dulcis (common almond), and two lectotypes and three neotypes are here designated.
The chloroplast genome of Amygdalus L. (Rosaceae) reveals the phylogenetic relationship and divergence time
The divergence time analyses based on the complete chloroplast genome sequences showed that subg.
Genetic structure of the endangered, relict shrub Amygdalus mongolica (Rosaceae) in arid northwest China
Investigating the influence of climatic fluctuations on the spatial genetic patterns and evolutionary history of organisms in arid northwest China found Amygdalus mongolica has likely experienced westward shifts from refugia along the margins of the Ulanbuhe and Tengger deserts, and also postglacial re-colonisation northward along the Hexi Corridor.
Genome re-sequencing reveals the evolutionary history of peach fruit edibility
The hypothesis that frugivore-mediated selection occurred several million years before the eventual human-mediated domestication of peach is supported and a large set of SNPs and/or CNVs, and candidate genes associated with fruit texture, taste, size, and skin color are identified, with implications for genomic-selection breeding in peach.
Genetic Resources of Almond Species in the Former USSR
Almonds are grown as an economically valuable crop in a number of countries worldwide, but large-scale cultivation has been primarily restricted to semiarid and arid regions with mild, temperate climates, and almond remains quite underused in areas outside those currently in cultivation.

The domain of the two-locus ycf1-ndhF genes are put forward as the most promising coding plastid DNA barcode in P. persica for further phylogeny study and species identification.


A phylogenetic analysis of Prunus and the Amygdaloideae (Rosaceae) using ITS sequences of nuclear ribosomal DNA.
The analyses suggest two major groups within the Amygdaloideae: PRUNUS: s.l. (sensu lato) and MADDENIA:, and (2) EXOCHORDA:, Oemleria, and PRINSEPIA: The ITS phylogeny supports the recent treatment of including EXO CHORDA: (formerly in the Spiraeoideae) in the Amydraesideae.
Phylogenetic inferences in Prunus (Rosaceae) using chloroplast ndhF and nuclear ribosomal ITS sequences
Both ITS and ndhF data sets suggest that the formerly recognized genus Pygeum is polyphyletic and that the distinction of the subgenera Padus and Laurocerasus is not supported, and the biogeographic interactions of the temperate and tropical members in the Padus/Laurocersasus/Maddenia alliance includingPygeum are shown to be highly dynamic and complex.
Phylogeny and Systematics of Prunus (Rosaceae) as Determined by Sequence Analysis of ITS and the Chloroplast trnL-trnF Spacer DNA
The objective of this study was to reconstruct the phylogeny of Prunus with the purpose of reviewing previously described taxonomic relationships and providing a basis for studies of morphological evolution in the genus.
Addressing the "hardest puzzle in American pomology:" Phylogeny of Prunus sect. Prunocerasus (Rosaceae) based on seven noncoding chloroplast DNA regions.
Prunus subg. Prunus sect. Prunocerasus (Rosaceae) is a North American taxon with 17 commonly recognized taxa. To test the hypothesis of monophyly for the section we sequenced the trnG and rpL16
Phylogenetic analysis of morphology in Prunus reveals extensive homoplasy
Prunus is a large and economically important genus with considerable morphological variation and some character states are likely adaptations to environments with higher humidity and mean temperature, however, these hypotheses need to be tested by including species formerly classified in genus Pygeum, which were not available for this study.
Phylogeny and classification of Rosaceae
Strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies is found, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets.
The genus Amygdalus L. (Rosaceae): Species relationships, distribution and evolution under domestication
The combined botanical and archaeological evidene points to the Levant countries as the place where the almond was taken into cultivation and the earliest archaeological signs of almond domestication come from this area.
Phylogenetic relationships in Rosaceae inferred from chloroplast matK and trnL-trnF nucleotide sequence data
Three main lineages appear to have diverged early in the evolution of the Rosaceae family: 1) Rosoideae sensu stricto, including taxa with a base chromosome number of 7; 2) actinorhizal Rosaceae, a group of taxa that engage in symbiotic nitrogen fixation; and 3) the rest of the family.

The taxon A. fenzliana (Fritsch) Lipsky is the most likely wild ancestor of almond for three reasons: It is a genuine wild type forming extensive thickets of large trees young seedlings and all the intergradations between them in nature; its morphology, and particularly the partially pitted grooved nut-shell are within the range of variation of almond.

Phylogenetic reconstruction of Prunus as determined by analysis of the combined data set suggests an early split into two clades, as a result of very short branches that may indicate rapid radiation.
