Phaseolin nucleotide sequence diversity in Phaseolus. I. Intraspecific diversity in Phaseolus vulgaris.
Most information about the molecular biology of phaseolin, the major seed storage protein in Phaseolus vulgaris, has been obtained from the T-type phaseolin, which is characteristic of the Andean gene pool of the species. In the work reported here, two cDNA clones for the S-type phaseolin representing the other major, Middle American gene pool were isolated and sequenced. Analysis of the DNA se...
متن کاملBackcross breeding for improved resistance to common bacterial blight in pinto bean (Phaseolus vulgaris
Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli reduces common bean (Phaseolus vulgaris L.) yield and quality worldwide. Genetic resistance provides effective disease control; however, a high level of resistance is difficult to attain and does not exist in pinto bean, the most important dry bean market class in North America. Our objective was to determine if a backc...
متن کاملGlycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...

متن کاملOligosaccharide Specificities of Phaseolus vulgaris
The structural determinants required for interaction of oligosaccharides with leukoagglutinating phytohemagglutinin (L-PHA) and erythroagglutinating phytohemagglutinin (E-PHA) from Phaseolus vulgaris have been studied by immobilized lectin affinity chromatography. Homogeneous oligosaccharides of known structure, purified following release from Asn with Nglycanase and reduction with NaBH4, were ...
