Abstract:
A 278-bp region upstream of the beet curly top virus-SpCT (BCTV-SpCT) C2/C3 genes is necessary for promoter activity and exhibits significant sequence similarity to AL2/3 promoter sequences in tomato golden mosaic virus (TGMV). Maximal expression of the downstream C2/3 genes in BCTV-SpCT requires the presence of the C1 protein, which is supported by observations that mutation of the initiator codon for C1 results in decreased C2/C3 expression. This is similar to TGMV and cabbage leaf curl virus, where AL1 is required for maximal AL2/3 expression. Together, these data suggest a common strategy for complementary-sense gene regulation amongst curtoviruses and begomoviruses.
