Fig. 7From: Autophagy counteracts instantaneous cell death during seasonal senescence of the fine roots and leaves in Populus trichocarpaRelative expression of ATG genes in fine roots (RC – root control, RS1 –first stage of root senescence, RS2 –second stage of root 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
