- •
Tolerance to South African cassava mosaic virus in TME3 is associated with sequestration of siRNAs, efficient PTGS and lower viral load.
- •
In susceptible T200, high numbers of vsRNAs correlated with high DNA A titres and severe symptoms.
- •
Lack of viral genome methylation was observed in both landraces.
- •
AC1, AV1 and the ORF overlapping regions are potential hotspots for DNA A.
- •
Both BC1 and BV1 on DNA B were evenly targeted by vsRNAs.
