Expression of three AtGUS genes and six AtUGT85A genes (A) and AtUBC8 as an internal loading control for RNA (B) in flowers, leaves, stems, siliques, and roots. All six AtUGT85As and three AtGUS generated products corresponding to the full-length mRNAs visible in ethidium bromide-stained gels. G3=AtGUS3, G1=AtGUS1, G2=AtGUS2, A1=AtUGT85A1, A3=AtUGT85A3, A5=AtUGT85A5, A2=AtUGT85A2, A7=AtUGT85A7, A4=AtUGT85A4, F=Flower, L=Leaf, St/Si=Stem/ Silique, R=Root, M=DNA size marker. MW scale applies directly to only G1-A2 of R, others are from other gels, aligned accordingly manually in the composite image (using the MW markers in the other gels)
