Figure 2From: Amino acidic substitutions in the polymerase N-terminal region of a reassortant betanodavirus strain causing poor adaptation to temperature increaseViral replication on E-11 cells. Data are expressed as viral RNA1 detected in E-11 cells supernatants. Means and standard deviations from three wells are presented. Letters indicate significant differences (p < 0.05) with: a RGNNV; b wt160; c r160.Back to article page
