A hypervariable intron of the locus provides excellent discrimination among accessions and reveals evidence for a relatively recent hybridization event with .

An analysis of 82 non-synonymous accessions for sequence variation in a fragment of the () locus revealed 57 alleles, most of which differed in indel structure. Eight additional accessions, each supposedly synonymous with a different accession of the initial group, were also analyzed. In every case the paired synonymous accessions possessed the same SGR sequence but varied slightly for a 6-trait morphological phenotype, indicating that SGR sequence is a much more reliable indicator of accession identity than is a morphological characterization.

Domestication of Pea ( L.): The Case of the Abyssinian Pea.

Phylogenetic relationships of the Abyssinian pea ( ssp. ) to other subspecies and species in the genus were investigated to test between different hypotheses regarding its origin and domestication. An extensive sample of the ssp.

Are Mendel's Data Reliable? The Perspective of a Pea Geneticist.

Mendel's data exhibit remarkable agreement to the ratios he predicted. In this article, alternative explanations for this close agreement (that inheritance in pea does not conform to the standard statistical model, that data were omitted, that ambiguous data were categorized to better match predicted ratios, and that some data were deliberately falsified) are tested using approaches that are designed to distinguish between these alternatives. The possibility that garden pea (Pisum sativum L.

Genetic analysis of an interspecific cross in ornamental Viburnum (Viburnum).

A genetic analysis was performed on a population derived from crosses between Viburnum lantana and Viburnum carlesii. Linkage maps were developed for each species using AFLP, random amplified polymorphic DNA (RAPD), and sequence-tagged site markers and a half-sib approach that took advantage of both the polymorphism between the species and the heterozygosity within each parent. The map for V.

Vigna (Leguminosae) sensu lato: the names and identities of the American segregate genera.

Premise Of Study: The legume genus Vigna and close relatives have highly elaborated floral morphologies that involve the coiling, bending, and intricate connection of flower parts. Banners, levers, platforms, and pumps have evolved that attract pollinators and then manipulate their movement. Given this three-dimensional floral complexity, the taxonomy of Vigna and relatives has been confounded by the study of mostly two-dimensional museum specimens.
