From: The flattened and needlelike leaves of the pine family (Pinaceae) share a conserved genetic network for adaxial-abaxial polarity but have diverged for photosynthetic adaptation

Spatiotemporal expression analyses of polarity genes. a Three developmental stages of Pinaceae leaves. Bars = 100 μm and bars = 1 mm for SEM and optical micrographs, respectively. b qPCR analyses of polarity genes in three leaf developmental stages. Error bars represent SD. c In situ localization of polarity genes in the vegetative tissues of Abies holophylla and Picea smithiana. LS, longitudinal sections; CS, cross sections. Bars, 100 μm
