BACKGROUND Phaseolamin or α-amylase inhibitor 1 (αAI) is a glycoprotein from common beans (Phaseolus vulgaris L.) that inhibits some insect and mammalian α-amylases. Several clinical studies support the beneficial use of bean αAI for control of diabetes and obesity. Commercial extracts of P. vulgaris are available but their efficacy is still under question, mainly because some of these extracts...

The genus Phaseolus (Fabaceae) consists of some 50 species, all of which are distributed in the Americas. Four of these contain cultigens. P. vulgaris (common bean), P. lunatus (lima bean), P. acutifolius (tepary bean), P. coccineus subsp. coccineus (runner bean); and P. coccineus subsp, polyanthus (no English vernacular name). Biochemical markers--phaseolin seed storage protein and isozymes--h...

A genome-wide analysis identified the set of small RNAs (sRNAs) from the agronomical important legume Phaseolus vulgaris (common bean), including novel P. vulgaris-specific microRNAs (miRNAs) potentially important for the regulation of the rhizobia-symbiotic process. Generally, novel miRNAs are difficult to identify and study because they are very lowly expressed in a tissue- or cell-specific m...

Recently, the genotype plus genotype x environment interaction (GGE) biplot methodology has been used to investigate genotype x environment interactions in several crop species, but has not been applied to the common bean (Phaseolus vulgaris L.) crop in Brazil. The aim of this study was to identify common bean genotypes that exhibit high grain yield and stability in the State of Mato Grosso do ...

field experiments were conducted in zanjan, markazi, esfahan, and chaharmahal va bakhtiari provinces to evaluate imazetapyr herbicide efficiency for weed control in common bean (phaseolus vulgaris l.) in 2006. there were four replications at each site and treatments were arranged in a randomized complete block design. in zanjan, maximum weed biomass reduction by 91 and 88 percent were achieved ...
