A new disease causing wilt and death of adult plants of Phaseolus vulgaris was discovered in plastic-house crops of southeast Spain in 2004. The causal agent was shown to be a Pythium species with a unique type of oogonium ornamentation different from any of the described species. Zoospores were not observed, but globose or subglobose hyphal swellings, intercalary or terminal, were frequently f...

Enniatins are cyclic depsipeptides produced by fungi of the genus Fusarium that are of interest due to their pronounced biological activities; especially enniatins A, A1, B, and B1 possess anticarcinogenic and anti-HIV properties. In the present study, F. tricinctum was grown on seven solid media and in one liquid growth medium with or without addition of peptone or of amino acid precursors in ...

Two methods were developed for the assay of substances stimulatory to the nodulation of bean (Phaseolus vulgaris) roots growing from segments of hypocotyl tissue. Coconut water was the chief source of active material, but extracts of cotyledons, hypocotyls and leaves of beans and of horse chestnut fruits were also stimulatory. High concentrations of nitrate improved nodulation both in the prese...

We report the possibility to modify the wetting properties of the surfaces of a diversity of seeds including: lentils (Lens culinaris), beans (Phaseolus vulgaris) and wheat (Triticum, species C9) by cold radiofrequency air plasma treatment. Air plasma treatment leads to the dramatic decrease in the apparent contact angle. Moreover, the speed of germination and yield (germination rate) of seeds ...

Phaseolus vulgaris (common bean) can be nodulated by several Rhizobium species. Among them, Rhizobium tropici has a relatively broad host range, as it is able to infect beans, Leucaena trees, and several other legumes. This work describes the isolation and the characterization of extracellular factors (Nod factors) whose production from R. tropici was triggered by the transcriptional activation...

Iron deficiency in higher plants causes accumulation of salts of organic acids in the roots, the most characteristic being citrate. We show that citrate and malate accumulate in beans (Phaseolus vulgaris L. var Prélude), not because of a lack of the iron-containing enzyme aconitase (EC 4.2.1.3), but in close coupling to the extrusion of protons during rhizosphere acidification, one of the ;Fe-e...

The aim of this study was to determine the antioxidant activity as well as total phenol (TPC) and total flavonoid content (TFC) in two fruits, apple (Malus domestica) and green beans (Phaseolus vulgaris). The antioxidant activities were examined by two different methods namely DPPH free radical scavenging activity and reducing power scavenging activity. The results showed that considerable amou...

The social and economic burden caused by chronic diseases such as obesity, diabetes, heart disease, and cancer is enormous. To reduce the impact of these diseases, we must find ways to reduce their prevalence. Epidemiological studies have found links between the incidence of cancer and consumption of dry edible bean {Phaseolus vulgaris L.) in the human diet. Correa (1981) examined data from 41 ...

Was reported literature findings of domestic and foreign articles about using biomass components (leaves, straw, pods, seeds) wastes beans (Phaseolus vulgaris) peas (Pisum sativum) pods shells processing as sorption material for pollutants (metals ions, colorants) removing from water environments. Concise Pisum sativum Phaseolus vulgaris plant structure, cultivation value, chemical composition ...

Legumes such as common beans (Phaseolus vulgaris L.) continue playing a critical role in making developed and developing economies food sustainable alternative sources to animal proteins. The crops bring together different stakeholders their value chain farmers, service providers, researchers policymakers. Web-based portals are emerging important tools that these can use perform various tasks, ...
