“…These differences suggest that P. glabellus is not to be considered as a subspecies of P. coccineus, as some have proposed (Delgado Salinas, 1988;Marechal & al., 1978). It differs by its ecological attributes, by the biochemical characteristics of its major seed storage proteins, and by the restriction site patterns of its cpDNA.…”

Biogeographic considerations as well as experimental hybridization, seed storage protein electrophoresis and cpDNA polymorphism point at its isolated taxonomic position and distinctness from P. coccineus. The position of P. glabellus in Phaseolus and its relationships with the remaining taxa of the P. coccineus complex are discussed.

We have analyzed the changes occurring in the chloroplast DNA (cpDNA) of taxa belonging to thePhaseolus vulgaris complex to help clarify relationships among species of this complex. Two restriction maps for 11 restriction enzymes comprising the whole chloroplast genome from a wildP. vulgaris and a wildP. coccineus accession were constructed. These maps allowed us to compare a total of 330 restriction sites between the two genomes in order to identify polymorphisms, assess the type of mutations detected, and identify regions of high variability. A region, located in the large single-copy region near the borders with the inverted repeats, accounted for a large portion of the variation. Most of the mutations detected were due to restriction sites gains or losses. Variable and conserved regions were then evaluated in 30 accessions belonging to taxa of theP. vulgaris complex. Phylogenetic analyses were made using parsimony methods. Conclusions obtained from such analyses were the following: (1) there was high cpDNA variability withinP. coccineus but not inP. vulgaris. (2)P. coccineus subsp.glabellus showed a very distinct cpDNA type that strongly suggests that it actually belongs to a different but as yet undetermined section of the genus. Our cpDNA observations are supported by distinctive morphological traits and reproductive biology of this taxon. (3) InP. coccineus subsp.darwinianus (also classified asP. polyanthus), the cpDNA lineage was in disagreement with data obtained from nuclear markers and suggested a reticulated origin by hybridization betweenP. coccineus as the male parent and an ancestralP. polyanthus type, closely allied toP. vulgaris, as the seed parent. This initial cross was presumably followed by repeated backcrossing toP. coccineus. Our cpDNA studies illustrate the importance of molecular markers in elucidating phylogenetic relationships. They also indicate that accurate phylogenies will require analyses of both nuclear and cytoplasmic genomes.

The genomic signature of wild-to-crop introgression during the domestication of scarlet runner bean (Phaseolus coccineusL.)

et al. 2022

The scarlet runner bean (Phaseolus coccineus) is one of the five domesticated Phaseolus species. It is cultivated in small‐scale agriculture in the highlands of Mesoamerica for its dry seeds and immature pods, and unlike the other domesticated beans, P. coccineus is an open‐pollinated legume. Contrasting with its close relative, the common bean, few studies focusing on its domestication history have been conducted. Demographic bottlenecks associated with domestication might reduce genetic diversity and facilitate the accumulation of deleterious mutations. Conversely, introgression from wild relatives could be a source of variation. Using Genotyping by Sequencing data (79,286 single‐nucleotide variants) from 237 cultivated and wild samples, we evaluated the demographic history of traditional varieties from different regions of Mexico and looked for evidence of introgression between sympatric wild and cultivated populations. Traditional varieties have high levels of diversity, even though there is evidence of a severe initial genetic bottleneck followed by a population expansion. Introgression from wild to domesticated populations was detected, which might contribute to the recovery of the genetic variation. Introgression has occurred at different times: constantly in the center of Mexico; recently in the North West; and anciently in the South. Several factors are acting together to increase and maintain genetic diversity in P. coccineus cultivars, such as demographic expansion and introgression. Wild relatives represent a valuable genetic resource and have played a key role in scarlet runner bean evolution via introgression into traditional varieties.
