ITPA and infection: These studies showed no change in expression of either ITPase‐like gene in response to UCBSV (Amuge et al., 2017) or mixed infection (Anjanappa et al., 2018) and a small increase in expression of a single ITPase gene (cassava4.1_014072m) of approximately 2‐fold in a resistant cassava variety following infection with CBSV (Maruthi et al., 2014).
