| conformational states of cowpea chlorotic mottle virus ribonucleic acid components. | the conditions determining conformational changes in the four ribonucleic acid components of cowpea chlorotic mottle virus have been studied. all four components have at least two electrophoretically separable conformers, the occurrence of which can be regulated by both monovalent and polyvalent cations. this phenomenon also occurs, in a much less striking way, in the ribonucleic acids of the two other members of the bromovirus group, brome mosaic virus and broad bean mottle virus. although spec ... | 1978 | 643624 |
| the nucleotide sequence and genome organization of the rna2 and rna3 segments in broad bean mottle virus. | complete nucleotide sequences of broad bean mottle virus (bbmv) genomic rnas 2 and 3 were determined. they consist of 2811 and 2293 nucleotides, respectively. both rnas are caped and, unlike in other tricornaviruses, both initiate with an a residue. bbmv rna2 is monocistronic and encodes an 815 amino acid 2a protein, whereas rna3 is dicistronic, encoding for a 295 amino acid 3a protein and for the 190 amino acid coat protein. a central, 423 amino acid 2a protein core region is highly homologous ... | 1992 | 1546462 |
| the nucleotide sequence and genome organization of the rna-1 segment in two bromoviruses: broad bean mottle virus and cowpea chlorotic mottle virus. | the complete nucleotide sequences of the rna-1 segments in broad bean mottle virus (bbmv) and cowpea chlorotic mottle virus (ccmv) were determined. bbmv rna-1 consists of 3158 nucleotides and ccmv rna-1 has 3171 nucleotides. both bbmv and ccmv rna-1 are capped at the 5' end but, unlike in other tricornaviruses, bbmv rna-1 initiates with an a residue. both bbmv and ccmv rna-1 are monocistronic encoding for highly homologous 1a proteins of 966 and 958 amino acids, respectively. the highest homolog ... | 1991 | 1962437 |

| trna-like structures of plant viral rnas: conformational requirements for adenylation and aminoacylation. | bromo- and cucumovirus rnas contain a trna-like structure as an integral part of their genome. this structure is located at the 3' end of the viral rna and is an acceptor of tyrosine. the 3' regions of representative viral rnas have been sequenced and quite unorthodox secondary foldings have been proposed for these 3' ends. the question therefore remained as to how these structures could be recognized by trna-specific enzymes. we have established the minimum number of nucleotides from the 3' end ... | 1983 | 6556143 |
| complete nucleotide sequence of spring beauty latent virus, a bromovirus infectious to arabidopsis thaliana. | spring beauty latent virus (sblv), a bromovirus, systemically and efficiently infected arabidopsis thaliana, whereas the well-studied bromoviruses brome mosaic virus (bmv) and cowpea chlorotic mottle virus (ccmv) did not infect and poorly infected a. thaliana, respectively. we constructed biologically active cdna clones of sblv genomic rnas and determined their complete nucleotide sequences. interestingly, sblv rna3 contains both the box b motif in the intercistronic region, as does bmv, and the ... | 2003 | 12536302 |
| do plant viruses facilitate their aphid vectors by inducing symptoms that alter behavior and performance? | aphids can respond both positively and negatively to virus-induced modifications of the shared host plant. it can be speculated that viruses dependent on aphids for their transmission might evolve to induce changes in the host plant that attract aphids and improve their performance, subsequently enhancing the success of the pathogen itself. we studied how pea aphids [acyrthosiphon pisum (harris)] responded to infection of tic beans (vicia faba l.) by three viruses with varying degrees of depende ... | 2008 | 19161702 |

| camelid nanobodies with high affinity for broad bean mottle virus: a possible promising tool to immunomodulate plant resistance against viruses. | worldwide, plant viral infections decrease seriously the crop production yield, boosting the demand to develop new strategies to control viral diseases. one of these strategies to prevent viral infections, based on the immunomodulation faces many problems related to the ectopic expression of specific antibodies in planta. camelid nanobodies, expressed in plants, may offer a solution as they are an attractive tool to bind efficiently to viral epitopes, cryptic or not accessible to conventional an ... | 2015 | 25648551 |
| effect of the host and temperature on the formation of defective rnas associated with broad bean mottle virus infection. | abstract previously, we demonstrated that broad bean mottle virus (bbmv), a member of the genus bromovirus, could accumulate rna 2-derived defective interfering (di) rnas during infection. in this work, we study how host and environmental factors affect the accumulation of di rnas. serial passages of bbmv through selected plant species reveal that, with low-multiplicity inocula, some systemic hosts (vicia faba, nicotiana clevelandii, and n. tabacum cv. samsum) support di rna accumulation after t ... | 2004 | 18943821 |
| a virulence-associated, 6.4-kb, double-stranded rna from rhizoctonia solani is phylogenetically related to plant bromoviruses and electron transport enzymes. | we have recently shown that acquisition of a 6.4-kb, double-stranded (ds) rna (m1) by hyphal anastomosis is associated with enhanced vigor and virulence, whereas its removal by hyphal tipping correlates with diminished virulence in the plant-pathogenic basidiomycete rhizoctonia solani. the m1 dsrna is not encapsidated by a typical nucleocapsid, has a circular and/or concatemeric form, and is associated with the mitochondrial and cytosolic fractions. m1 possesses six open reading frames (orfs) th ... | 1998 | 9650294 |
| characterization of defective interfering rna components that increase symptom severity of broad bean mottle virus infections. | several strains of the broad bean mottle virus (bbmv), an icosahedral tripartite plant rna virus, which show distinct reactions on certain plant hosts have been described (k. m. makkouk et al., neth. j. plant pathol. 94, 195-212, 1988). here we report defective interfering (di) rnas encapsidated in two bbmv strains from morocco and tunisia. while not effective in some plants, these di rnas exacerbated the severity of symptoms in others. the most dramatic, lethal effect of di rnas has been found ... | 1993 | 8503176 |
