Abstract
Bromoviruses are representative members of the alphavirus-like superfamily of animal and plant positive-strand RNA viruses. Tractable biochemical and genetic features have made bromoviruses useful systems forin vivoandin vitrostudies ofcis-acting RNA sequences andtrans-acting factors in RNA replication, subgenomic mRNA synthesis, translation, encapsidation, and virus–host interactions. Among other findings, bromoviruscis-acting RNA replication signals are large, structurally complex, and conserve potential conformational switches that may coordinate RNA replication with other infection processes. The tRNA-like 3′ ends of bromovirus RNAs are required for negative-strand synthesis and recognized by multiple tRNA-specific host enzymes. The presence of additional host regulatory sequence motifs in other bromoviruscis-acting regions suggests that their function also involves interaction with host as well as viral factors.
