Mitochondrial Genome Sequence of the Legume Vicia faba.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
The number of plant mitochondrial genomes sequenced exceeds two dozen. However, for a detailed comparative study of different phylogenetic branches more plant mitochondrial genomes should be sequenced. This article presents sequencing data and comparative analysis of mitochondrial DNA (mtDNA) of the

In a study to evaluate the potential of Vicia faba (faba bean) as a cover and forage crop for Florida, 60 accessions of faba bean with diverse genetic backgrounds and geographic origins were acquired from the USDA Germplasm Repository in Pullman, WA. The beans were grown south of Lake Okeechobee in
A novel seed protein gene from Vicia faba is developmentally regulated in transgenic tobacco and Arabidopsis plants.

We have isolated a novel gene, denoted USP, from Vicia faba var. minor, which corresponds to the most abundant mRNA present in cotyledons during early seed development; however, the corresponding protein does not accumulate in cotyledons. The characterized USP gene with its two introns is 1 of about
First Report of Branched Broomrape (Orobanche ramosa) on Oilseed Rape (Brassica napus), Wild Mustard (Sinapis arvensis), and Wild Vetch (Vicia spp.) in Northern Greece.

Branched broomrape (Orobanche ramosa L.) is a chlorophyll-lacking, root parasitic plant that infects many crops and wild species (2). Plants are densely hairy with minute, glandular hairs, particularly on flowers and upper stems. Stems are erect, often branched just above the ground, and brown to
The promoter of the Vicia faba L. leghemoglobin gene VfLb29 is specifically activated in the infected cells of root nodules and in the arbuscule-containing cells of mycorrhizal roots from different legume and nonlegume plants.

The VfLb29 leghemoglobin gene promoter was polymerase chain reaction-amplified from a Vicia faba genomic library and was fused to the gusAint coding region. Expression of the chimeric gene was analyzed in transgenic hairy roots of the legumes V. faba, V. hirsuta, and Medicago truncatula as well as
Effects of ZnO nanoparticles in plants: Cytotoxicity, genotoxicity, deregulation of antioxidant defenses, and cell-cycle arrest.

Cytotoxicity, genotoxicity, and biochemical effects were evaluated in the plants Allium cepa, Nicotiana tabacum, and Vicia faba following exposure to ZnO nanoparticles (np; diameter, ∼85nm). In the root meristems of Allium cepa cells, we observed loss of membrane integrity, increased chromosome
A chimeric gene encoding the methionine-rich 2S albumin of the Brazil nut (Bertholletia excelsa H.B.K.) is stably expressed and inherited in transgenic grain legumes.

The coding region of the 2S albumin gene of Brazil nut (Bertholletia excelsa H.B.K.) was completely synthesized, placed under control of the cauliflower mosaic virus (CaMV) 35S promoter and inserted into the binary vector plasmid pGSGLUC1, thus giving rise to pGSGLUC1-2S. This was used for
Molecular and biological characterization of highly infectious transcripts from full-length cDNA clones of broad bean wilt virus 1.

Broad bean wilt virus 1 (BBWV-1), genus Fabavirus, has a genome composed of two single-stranded positive-sense RNAs of ∼5.8 (RNA1) and 3.4kb (RNA2). Full-length cDNA clones of both genomic RNAs (pBenR1 and pBenR2) from BBWV-1 isolate Ben were constructed under the control of the T7 promoter. In
Detection of an unidentified potyvirus from Roystonea regia palm using the polymerase chain reaction and degenerate, potyvirus specific, primers and potential problems arising from the amplification of host plant DNA sequences.

The plant growth regulator and herbicide maleic hydrazide (MH) induced a high frequency of somatic mutations in leaves of tobacco (Nicotiana tabacum var. xanthi) and a high yield of chromosome aberrations in roots of field beans (Vicia faba, karyotype ACB). In contrast, no significant increase in
