Grain legumes, such as soybean (Glycine max (L.) Merr.), pea (Pisum sativum L.), faba bean (Vicia faba L.), lupins (Lupinus spp.), common vetch (Vicia sativa L.) and grass pea (Lathyrus sativus L.), represent one of the most quality and least expensive solutions for a long-term demand for plant protein in animal husbandry. One of the limitations to an increased use of grain legumes as feed is t...

a restriction-site analysis of chloroplast dna (cpdna) was carried out to evaluate the levelof diversity in vicia faba l. germplasm selected from different geographical regions using 11 restrictionendonucleases. we analyzed 214 restriction sites in 18 accessions of vicia faba. all of the accessionshad identical cpdnas, pointing out the ancestral character of all the accessions are of only one g...

X-ray CT is a powerful technology to study root growth in soil in-situ. Root systems can be studied in its true 3D geometry over time. Hence, the same plant can be scanned multiple times during development. A downside is the potential of X-rays to interfere with biological processes and therefore plant growth. The aim of this study is to evaluate the influence of cumulative X-ray dose on Vicia ...

Sequence-related amplified polymorphism (SRAP) markers were used to assess the genetic diversity and relationship among 58 faba bean (Vicia faba L.) genotypes. Fourteen SRAP primer combinations amplified a total of 1036 differently sized well-resolved peaks (fragments), of which all were polymorphic with a 0.96 PIC value and discriminated all of the 58 faba bean genotypes. An average pairwise ...

Extrafloral (EF) nectaries recruit carnivorous arthropods that protect plants from herbivory, but they can also be exploited by nectar thieves. We studied the opportunistic, targeted predation (and destruction) of EF nectaries by insects, and the localized chemical defences that plants presumably use to minimize this effect. In field and laboratory experiments, we identified insects that were p...

The present investigation aims to study the intraspecific diversity of thirteen faba bean genotypes (Vicia faba L. 2n=12) and to determine some selection criteria for plant breeding. Five yield parameters were studied: plant height (H), branch number per plant (BN/Pl), pod number per plant (PN/Pl), seed number per pod (SN/P) and yield per plant (Y/Pl). With a few exceptions, significant variabi...

The average opening rate of Vicia faba L. stomata was determined over an initial 20-minute light period following darkness. Nonsaturating intensities of broad band red and blue light had similar quantum effectiveness for the promotion of opening, whereas broad band green was about 40% and far red about 5% as effective. The opening rates under saturating red, green, and blue light were the same....

ଝ Consumo de habas (Vicia faba) y enfermedad de Parkinson: una fuente natural de L-dopa a tener en cuenta Dear Editor: Scientists know that broad beans (Vicia faba) contain enough L-dopa to be pharmacologically active on patients with Parkinson's disease (PD). It has been shown that these beans increase plasma levels of L-dopa and improve motor function. 1 We present the case of a patient with ...

Liriomyza huidobrensis (Blanchard) is an economically important and highly polyphagous worldwide pest. To establish a temperature-dependent phenology model, essential for understanding the development and growth of the pest population under a variety of climates and as part of a pest risk analysis, L. huidobrensis life-table data were collected under laboratory conditions at seven constant temp...

We have re-examined the nucleotide sequence of Vicia faba (broad bean) 5.8S rRNA using partial chemical degradation and a new approach to high temperature (65-80 degrees C) sequencing gels. The results indicate that the secondary structure was not completely disrupted in previous studies (Tanaka, Y., Dyer, T.A. and Brownlee, G.G. (1980) Nucleic Acid Res. 8, 1259-1272) and explain ambiguities be...
