The monopartite DNA genome of beet curly top geminivirus (BCTV, strain Logan) contains four leftward (complementary sense) open reading frames (ORFs) designated L1, L2, L3, and L4. We investigated the functions of the L2 and L3 ORFs by mutational analysis. We found that in Nicotiana benthamiana and sugarbeet plants, neither a functional L2 nor a functional L3 gene is required for infectivity. Double mutants were also infectious, and no evidence for a synergistic effect of these genes was… CONTINUE READING
