Common beans (Phaseolus vulgaris) are excellent sources of dietary folates, but different varieties contain different amounts of these compounds. Genes coding for dihydroneopterin aldolase (DHNA) and aminodeoxychorismate synthase (ADCS) of the folate synthesis pathway were characterized by PCR amplification, BAC clone sequencing, and whole genome sequencing. All DHNA and ADCS genes in the Mesoa...

Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plant growth promoting rhizobacteria (PGPR) were isolated from common bean nodules from Nakuru County in...

Relatively few studies have extensively analysed the genetic diversity of the runner bean through molecular markers. Here, we used six chloroplast microsatellites (cpSSRs) to investigate the cytoplasmic diversity of 331 European domesticated accessions of the scarlet runner bean (Phaseolus coccineus L.), including the botanical varieties albiflorus, bicolor and coccineus, and a sample of 49 dom...

Nodule bacteria (rhizobia) in symbiotic associations with legumes enable considerable entries of biologically fixed nitrogen into soil. Efforts are therefore made to intensify the natural process of symbiotic nitrogen fixation by legume inoculation. Studies of field populations of rhizobia open up the possibility to preserve and probably exploit some indigenous strains with hidden symbiotic or ...

a procedure for the in vitro evaluation of the toxicity of fava beans has been applied to 17 varieties of the bean and one batch of beans purchased on the open market; the latter consisted of unknown varieties. the procedure involves the incubation of a saline extract of the beans with red cells from normal individuals and with red cells from g6pd deficient patients. 2. normal red cells under t...

Common bean is the most important legume worldwide for direct human consumption. Beans constitute an important source of dietary protein for over half a billion people mainly in developing countries. A great number of bacterial, fungal, and viral diseases occur annually in bean-producing regions all over the world, causing economic losses to bean producers. Major improvements in agronomic trait...

The photosynthetic characteristics of two contrasting varieties of common bean (Phaseolus vulgaris) have been determined. These varieties, Arroz and Orfeo, differ in their productivity under stress conditions, resistance to drought stress, and have distinctly different stomatal behaviour. When grown under conditions of high irradiance and high temperature, both varieties displayed evidence of p...

Considering the crucial focus on plant developments as high yielding, protein, and disease-resistant varieties, in this study, the genetic diversity and nutritional traits of available kidney bean germplasms found in Bangladesh have been evaluated based on seventeen quantitative and six nutritional traits. Analysis of genotypic, phenotypic variance and covariance showed that higher environmenta...
