Ongoing characterization of cis-acting sequences in bromovirus RNA-dependent RNA replication and transcription has been complemented in the past year by progress in elucidating the roles of virus-encoded replication factors 1a and 2a. Recent studies suggest that the helicase-like 1a and polymerase-like 2a proteins may participate in a well organized replication complex in which polymerase, helicase, and possibly capping functions operate in a highly coordinated manner.

UI	MeSH Term	Description	Entries
D010942	Plant Viruses	Viruses parasitic on plants.	Phytophagineae,Plant Virus,Virus, Plant,Viruses, Plant
D012313	RNA	A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.
