highly significantp=0.0007
Under R → RB → R and the reverse sequence, RB → R → RB, fitting the g s data to a linear mixed-effects model ( Tables S8 and S9 ) showed a highly significant effect of light (R-RB-R, p=0.0007;RB-R-RB, p=0.0060), but the main effect of species (R-RB-R, p=0.3455; RB-R-RB, p=0.8859) and its interaction with light (R-RB-R, p=0.2055; RB-R-RB, p=0.7486) were not significantly different.
