Expression of a glycine decarboxylase complex H-protein in non-photosynthetic tissues of Populus tremuloides.
The Gly decarboxylase complex (GDC) is abundant in mitochondria of C3 leaves and functions in photorespiratory carbon recovery. However, expression of GDC component proteins has generally been less evident in non-green tissues. Here we report an aspen (Populus tremuloides Michx.) PtgdcH1 gene, encoding a GDC subunit H-protein that is phylogenetically distinct from previously characterized photorespiratory H-proteins. Strong expression of PtgdcH1 in root tips and developing xylem suggests that GDC supports a very active C1 metabolism in non-photosynthetic tissues of aspen.
