The vein networks of plant leaves are among the most spectacular expressions of biological pattern, and the principles controlling their formation have continually inspired artists and scientists. Control of vein patterning by the polar, cell-to-cell transport of the plant signaling molecule auxin--mediated in Arabidopsis primarily by the plasma-membrane-localized PIN1--has long been known. By contrast, the existence of intracellular auxin transport and its contribution to vein patterning are… CONTINUE READING
