Rhizobium — Host Specificities in Phaseolus coccineus L. and Phaseolus vulgaris L. 1

Rhizobium - Host Specificities in Pbaseolus coccineus L. and Pbaseolus vulgaris L

The introduction of desirable agronomic characteristics into Phaseolus vulgaris L. is being attempted by interspecific hybridization with P. coccineus, but the effects on root nodulation are unknown. Accordingly, cross-inoculation relationships between P. vulgaris `Red Kidney' and P. coccineus ’Scarlet Runner' were tested in the greenhouse with a group of 16 Rhizobium strains effective on Red K...

Oligosaccharide 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 ...

List of Genes - Phaseolus vulgaris L

Studies of l-Cysteine Biosynthetic Enzymes in Phaseolus vulgaris L.

In higher plants the biosynthesis of l-cysteine from l-serine, acetylCoA, and sulfide requires serine transacetylase and O-acetylserine sulfhydrylase. The distribution of these enzymes in kidney bean (Phaseolus vulgaris L. cv. Red Kidney) seedlings was determined. Between one-third and two-thirds of the serine transacetylase activity was associated with mitochondria, whereas all of the O-acetyl...

Rhizobium tropici, a novel species nodulating Phaseolus vulgaris L. beans and Leucaena sp. trees.

A new Rhizobium species that nodulates Phaseolus vulgaris L. and Leucaena spp. is proposed on the basis of the results of multilocus enzyme electrophoresis, DNA-DNA hybridization, an analysis of ribosomal DNA organization, a sequence analysis of 16S rDNA, and an analysis of phenotypic characteristics. This taxon, Rhizobium tropici sp. nov., was previously named Rhizobium leguminosarum biovar ph...
