Chia (Salvia hispanica), an herbaceous plant native to Latin America, has become important in the last 20 years due to its beneficial effects on health. Here, we present the first record and identification of two viruses in chia plants. The comparison of the complete nucleotide sequences showed the presence of two viral species with the typical genome organization of bipartite New World begomov...

Plant virus vectors provide an attractive biotechnological tool for the transient expression of foreign genes in whole plants. As yet there has been no use of recombinant viruses for the improvement of commercial crops. This is mainly because the viruses used to create vectors usually cause significant yield loss and can be transmitted in the field. A novel attenuated zucchini yellow mosaic pot...

The serological interrelationships between eleven viruses in the turnip yellow mosaic virus group (tymoviruses) were studied with 286 antisera from 48 rabbits. Antisera from different rabbits and from different bleedings of the same rabbit showed considerable differences in their homologous and heterologous reactivities. A classification based on average serological differentiation indices is p...

The serological interrelationships between eleven viruses in the turnip yellow mosaic virus group (tymoviruses) were studied with 2% antisera from 48 rabbits. Antisera from different rabbits and from different bleedings of the same rabbit showed considerable differences in their homologous and heterologous reactivities. A classification based on average serological differentiation indices is pr...

The coat protein of belladonna mottle virus (a tymovirus) was cleaved by trypsin and chymotrypsin, and the peptides were separated by high performance liquid chromatography using a combination of gel permeation, reverse phase, and ion pair chromatography. The peptides were sequenced manually using the 4-N, N-dimethylaminoazobenzene-4'-isothiocyanate/phenyl isothiocyanate double-coupling method....
