Fig. 8From: Autophagy counteracts instantaneous cell death during seasonal senescence of the fine roots and leaves in Populus trichocarpaRelative expression of ATG genes in leaves (LC – leaf control, LS1 –first stage of leaf senescence, LS2 – second stage of leaf senescence) of Populus trichocarpa. Bars sharing the same letter are not significantly different (P = 0,05). Values represent the mean ± SE (standard error)Back to article page
