Typical symptoms of RSMV infection in rice. a Plant heights of three RSMV-infected varieties at 75 dpi. b Stiff, twisted leaves of RSMV-infected Wuyou 1179 at 45 dpi. c Mosaicism on leaf blade surfaces and undersides of Meixiangzhan at 45 dpi. d Plant heights of the three RSMV-infected varieties at 60 dpi. (Meixiangzhan: df = 22.035, SD = 1.98, p < 0.0001; Nipponbare: df = 28, SD = 1.34, p < 0.0001; Wuyou 1179: df = 15.705, SD = 2.91, p < 0.0001) e SPAD values of the three infected varieties at 45 dpi. (Meixiangzhan: df = 26.036, SD = 1.057, p < 0.0001; Nipponbare: df = 17.860, SD = 1.34, p < 0.0001; Wuyou 1179: df = 28, SD = 0.86, p < 0.0001) f–g Leaf lignin (f) and galactose (g) contents of the three infected varieties (Leaf lignin Contents: Meixiangzhan: df = 1, p = 0.05; Nipponbare: df = 1, p = 0.513; Wuyou 1179: df = 1, p = 0.05; Leaf galactose Contents: Meixiangzhan: df = 1, p = 0.05; Nipponbare: df = 1, p = 0.827; Wuyou 1179: df = 1, p = 0.05) Values in d–g are means ± s.d. (d–e, n = 15 plants; f-g, n = 3 replicates). Significant differences are indicated by asterisks: *, significant (P < 0.05); **, highly significant (P < 0.01)
