  1. The data are presented as means ± standard error. Number of replicates is indicated in parentheses. Biological parameters were analyzed using general linear models (GLMs) followed by Tukey’s multiple range test. Different letters in the same row indicate significant difference among treatments (P < 0.05). Factor A: rice type; Factor B: RDV infection status; FA×B: the interaction of rice type and RDV infection status.
