Abstract

The structure and function of a regulatory gene, SCARECROW (SCR), is described. The SCR gene is expressed specifically in root progenitor tissues of embryos, and in roots and stems of seedlings and plants. SCR expression controls cell division of certain cell types in roots and affects the organization of root and stem tissues, and affects gravitropism of aerial structures. The invention relates to the SCARECROW (SCR) gene, SCR gene products, (including but not limited to transcriptional products such as mRNAs, antisense, and ribozyme molecules, and translational products such the SCR protein, polypeptides, peptides and fusion proteins related thereto), antibodies to SCR gene products, SCR promoters and regulatory regions and the use of the foregoing to improve agronomically valuable plants.
