Expression of XXT1, XXT2, GT3, GT4, and XXT5 in Arabidopsis organs. The AtGE Development series (Schmid et al., 2005) was queried for XXT1 (At3g62720), XXT2 (At4g02500), GT3 (At5g07720), GT4 (At1g18690), and XXT5 (At1g74380) expression using the AtGenExpress Visualization Tool (http://jsp.weigelworld.org/expviz/expviz.jsp). Gene expression in roots, hypocotyls, leaves (composed of the first two leaves to emerge), whole rosettes from 7-d-old seedlings, and stems from 21-d-old plants is shown.
