Global gene expression: effects of species and climate regime Global gene expression varied most strongly between species (PERMANOVA: F 2 = 10.6, r 2 = 0.20, P = 0.0001), followed by treatment (F 2 = 1.8, r 2 = 0.034, P = 0.029) and a marginally nonsignificant species:treatment interaction (F 4 = 1.4, r 2 = 0.054, P = 0.069) ( Fig. 1 ).
