Article Synopsis
- Cassava mosaic disease is caused by begomoviruses transmitted by whiteflies, existing as populations with two essential genome segments (DNA-A and DNA-B) that must be transmitted together for infection.
- The study focused on how different titers of these DNA segments in infected cassava plants influenced the whiteflies' ability to acquire and transmit each segment.
- Results showed that the acquisition probabilities of ACMV segments were not directly related to their plant titers, while EACMCV segment acquisition did reflect this; however, the transmission ratios remained consistent, suggesting a balance for the highest transmission efficiency.
Cassava is a root crop important for global food security and the third biggest source of calories on the African continent. Cassava production is threatened by Cassava mosaic disease (CMD), which is caused by a complex of single-stranded DNA viruses (family: , genus: ) that are transmitted by the sweet potato whitefly (). Understanding the dynamics of different cassava mosaic begomovirus (CMB) species through time is important for contextualizing disease trends.
