Fig. 1: Effect of Y-satellite (Y-sat) infection on tobacco growth and virus transmission by aphids.
From: A plant virus satellite RNA directly accelerates wing formation in its insect vector for spread
a Yellowing was induced in (cucumber mosaic virus [CMV] + Y-sat)-infected plants but not the CMV-infected or healthy at 14 d.p.i. Note that [CMV + Y-sat]-infected plants had few abnormally shaped leaves. b Each data point represents the relative CMV levels in CMV- and [CMV + Y-sat]-infected plants determined by qPCR. Data are mean values (±SE) (two-sided t test, n = 5, P = 0.0037). **P < 0.01. c Efficiency of aphid transmission of virus from CMV-infected and [CMV + Y-sat]-infected plants to healthy plants (χ2 test, P = 0.0352). d CMV transmission efficiency by apterous and alate aphids (χ2 test, P > 0.9999). e–h Mean (±SE) photosynthetic rate in CMV-O (or -L)-infected, [CMV + Y-sat]-infected and healthy leaves at 30 d.p.i. at various photosynthetic proton flux densities (PPFD) µmol m−2 s−1. Individual data points are mean values of each plant (e, n = 4; g, n = 3). f, h Mean (±SE) photosynthetic rate among infection types were analysed at 120 and 1200 PPFD by one-way ANOVA with Tukey’s multiple comparison test (n = 4, values followed by the same letters are not significantly different at P < 0.05). 120 PPFD: CMV-O-infected (P = 0.5914); CMV-L-infected (P = 0.9293). 1200 PPFD: CMV-O-infected (P = 0.9256); CMV-L-infected (P = 0.1695).
