To investigate similarities between symbiotic interactions of broad bean (Vicia faba) with rhizobia and mycorrhizal fungi, plant gene expression induced by both microsymbionts was compared. We demonstrated the exclusive expression of 19 broad bean genes, including VfENOD2, VfENOD5, VfENOD12 and three different leghemoglobin genes, in root nodules. In contrast, the leghemoglobin gene VfLb29 was ...

Black and Pinto bean starches were physically and chemically modified to investigate the effect of modification on digestibility and physicochemical properties of bean starch. The impact of acetylation, oxidation (ozonation) and annealing on the chemical composition, syneresis, swelling volume, pasting, thermal properties and digestibility of starches was evaluated. The physicochemical and esti...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...

Pulses are grain legumes that have sustained the civilisations of the world throughout their development; yet this staple food crop has fallen into disuse, particularly in Westernised societies, and decreased consumption parallels increased prevalence of CVD. The objective of the present study was to identify mechanisms that account for the cardioprotective activity of dry bean (Phaseolus vulga...

The following asymptotic result is proved. For every fixed graph H with h vertices, any graph G with n vertices and with minimum degree d ≥ χ(H)−1 χ(H) n contains (1− o(1))n/h vertex disjoint copies of H. ∗Research supported in part by a United States Israel BSF Grant and by a Bergmann Memorial Grant

U4 RNA, which is known to play an indispensable role in pre-mRNA splicing, is present in plant nuclei, has a canonical m3 2,2,7 G cap at its 5' end and is associated with U6 RNA in snRNP particles. It occurs in broad bean in the form of a number of sequence variants. Two of these were sequenced: U4A RNA is 154 and U4B RNA is 152 nucleotides long. Sequence similarity of broad bean U4B RNA is 94 ...

Phosphorus (P), an essential element for plants, is one of the most limiting nutrients for plant growth. A few transcription factor (TF) genes involved in P-starvation signalling have been characterized for Arabidopsis thaliana and rice. Crop production of common bean (Phaseolus vulgaris L.), the most important legume for human consumption, is often limited by low P in the soil. Despite its agr...

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...

Dry bean (Phaseolus vulgaris L.) consumption is associated with reduced risk for a number of chronic diseases. In westernised societies, dry bean consumption is particularly low (approximately 2-4 kg/capita per year) and little information is available about the safety of increasing dietary intake in humans to achieve levels that prevent and control chronic diseases. In anticipation of a human ...

Soya bean (Glycine max (L.) Merr.) is sought after for both its oil and protein components. Genetic approaches to add value to either component are ongoing efforts in soya bean breeding and molecular biology programmes. The former is the primary vegetable oil consumed in the world. Hence, its primary usage is in direct human consumption. As a means to increase its utility in feed applications, ...
