Genetic variation of Citrus tristeza virus isolates from California and Spain: evidence for mixed infections and recombination.

abstract：:We describe here the neurovirulence properties of a herpes simplex virus type 1 gamma34.5 second-site suppressor mutant. gamma34.5 mutants are nonneurovirulent in animals and fail to grow in a variety of cultured cells due to a block at the level of protein synthesis. Extragenic suppressors with restored capacity to r...
