Fig. 3From: A detailed expression map of the PIN1 auxin transporter in Arabidopsis thaliana rootChanges in PIN1 expression during lateral root primordium development. a–g The seven stages of primordium development are shown in roman numerals. IL (IL1, IL2)—inner layers, OL (OL1, OL2)—outer layers. Pre-specified QC cells are marked by asterisks. Developing tissues: epid—epidermis, c—cortex, en—endodermis. White arrows show the directions of auxin flux. Anti-PIN1 staining is in green, DAPI is in the blue channel. Bars = 50 μmBack to article page
