    Notes: Summary Crude protein extracts from single seeds of nondomesticated Mexican bean accessions were analysed by SDS polyacrylamide gel electrophoresis for variability in phaseolin protein. Six new phaseolin types; ‘M1’, ‘M2’, ‘M3’, ‘M4’, ‘M5’, ‘M6’, which contained polypeptides within the same range of molecular weights (51,000 to 45,000 daltons) as occur in the ‘S’, ‘T’ and ‘C’ phaseolin types of cultivated beans were identified. No ‘T’ and ‘C’ types were found among the non-domesticated Mexican accessions, and the ‘S’ type occurred in less than 7% of the seeds screened. Genetic analyses of F2 progenies from crosses between ‘Sanilac’ (‘S’), and five of the ‘M’ types showed that each ‘M’ phaseolin phenotype was allelic to the ‘S’ type and expressed codominantly.

    Notes: Summary SDS-PAGE of seed proteins from the seeds of a nondomesticated bean of Mexican origin (Phaseolus vulgaris L., PI 325690) revealed the presence of a novel 38 kd protein which appeared to be neither an altered phaseolin nor a lectin fraction. The protein was named arcelin, after Arcelia, the town in the state of Guerrero near which PI 325690 had been collected. The pure line, UW 325, was derived by self fertilization of the plant from a single arcelin-containing seed of PI 325690. Despite a low percentage seed phaseolin (14.6%), seed phenotype, seed germination, plant growth, pollen fertility, and percentage seed protein of UW 325 were normal. Analyses of F2 and F3 seeds from a single F1 plant of the cross ‘Sanilac’XPI 325690-3 revealed that arcelin expression was inherited as a single gene and that presence was dominant to absence of arcelin. The mean percentage phaseolin in the seeds of homozygous dominant Arc/Arc F3 families (14.0%) was significantly lower than that of the homozygous recessive arc/arc seeds (44.7%). The distribution of percentage phaseolin values for seeds within segregating families was bimodal and nonoverlapping. Without exception, seeds containing arcelin (Arc+phenotype) contained a lower percentage phaseolin than seeds lacking arcelin (Arc-phenotype). Although arcelin presence was associated with low percentage phaseolin, the Arc/Arc and Arc/arc genotypes were similar for seed weight and percentage total seed protein.

    Bean lectins (1985)

    Notes: Summary Seeds of forty bean cultivars having different lectin types based on two-dimensional isoelectric focusing-sodium dodecyl sulfate polyacrylamide gel electrophoresis (IEF-SDS/PAGE) were analyzed for quantities of lectin, phaseolin and total protein. Significant differences were found among groups of cultivars with different lectin types for the quantity of lectin and phaseolin. Cultivars with more complex lectin types based on IEF-SDS/PAGE tended to have higher quantities of lectin and lower quantities of phaseolin than cultivars with simple lectin types. An association between lectin type and the quantity of lectin and phaseolin was found also in the seeds of F2 plants that segregated in a Mendelian fashion for two lectin types. Seeds from plants with the complex lectin type had more lectin and less phaseolin than seeds from plants with the simple lectin type. Therefore, the genes controlling qualitative lectin variation also may influence the quantitative variation of lectin and phaseolin. The results of this study are related to other studies on the quantitative variation for seed proteins and to the possible molecular basis for variation in the quantity of lectins in beans.

    Notes: Summary The inheritance of phaseolin and globulin-2 (G2)/albumin polypeptides was investigated in crosses involving varieties which exhibited the three electrophoretic banding patterns of phaseolin found in French bean. ‘Total’ seed protein extracts of single seeds of the F1 and F2 generations from the crosses: ‘Sanilac’ × ‘Contender’, ‘BBL 240’ × ‘Contender’, and ‘Sanilac’ × ‘BBL 240’ were analyzed by two-dimensional electrophoresis. Segregation of the genes controlling phaseolin and G2/albumin polypeptides, and those controlling a further five groups of seed proteins (A, B, D, E, and F) were observed. No recombinant electrophoretic phenotypes were seen for phaseolin or G2/albumin polypeptides suggesting that the genes controlling each of these groups of polypeptides are closely linked and segregate like single Mendelian genes. The phaseolin genes and G2/albumin genes were not linked to each other. The group of genes controlling phaseolin polypeptides were linked to those controlling group B proteins, and those controlling G2/albumin polypeptides were linked to those controlling group F proteins.
