RT   monopartite geminivirus.";

CC   -!- FUNCTION: Pathogenicity determinant (By similarity). May act as a
CC       suppressor of RNA-mediated gene silencing, also known as post-
CC       transcriptional gene silencing (PTGS), a mechanism of plant viral
CC       defense that limits the accumulation of viral RNAs. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the geminiviridae protein AC4/C4 family.
CC       {ECO:0000305}.
