A number of taxonomic proposals were approved by the Executive Committee of the International Committee on Taxonomy of Viruses (ICTV) at its meeting in Houston earlier this year, and the resulting changes include the creation of 6 new families and 8 new genera.

The 30th meeting of the Executive Committee of the International Committee on Taxonomy of Viruses (ICTV) was held at Baylor College of Medicine, Texas Medical Center, Houston, Texas on the 7th and 8th of March of this year and there were taxonomic proposals, the ICTV database and ICTV activities at the coming International Virology Congress.
Nucleotide sequence of potato leafroll luteovirus RNA.
The amino acid sequences encoded by the 3' block of coding sequence show many similarities with analogous polypeptides translated from the nucleotide sequences of RNA of barley yellow dwarf virus, PAV strain (BYDV) and, in particular, beet western yellows virus (BWYV).
Expression of biologically active viral satellite RNA from the nuclear genome of transformed plants
A means of protecting plants against the effects of CMV is suggested and a method by which satellite RNAs may have evolved is suggested.
Proposed re-classification of furoviruses.
Umbravirus gene expression helps potato leafroll virus to invade mesophyll tissues and to be transmitted mechanically between plants.
Pato leafroll virus was mechanically transmissible when inocula also contained the umbravirus Pea enation mosaic virus-2 (PEMV-2), and possibly both a cell-to-cell movement function and counterdefense mechanisms such as those that block posttranscriptional gene silencing are involved in movement of PLRV within plants and its mechanical transmission between plants.
Occurrence of Tobacco streak virus on Peanut (Arachis hypogaea) in India.
The results indicate that the causal agent of PSND is Tobacco streak virus (TSV), and the identification of virus-resistant peanut genotypes have been initiated to devise strategies to control PSND.
