Abstract: A method by which many plants control organ shape is by regulated, differential cellular expansion. A gene involved in regulating the expansion of plants cells, such as Arabidopsis thaliana root cells is COBRA which encodes a protein with a putative GPI anchor. Plants comprising altered root morphologies may be produced by control of COBRA activity. For example, roots which lack COBRA activity comprise thicker, fatter roots (a CORE or cob phenotype) which are well suited for penetrating dense, compacted soil. Plants lacking COBRA activity may be useful in applications wherein plant growth in areas with dense soil would be beneficial. The present invention comprises the Arabidopsis thaliana COBRA gene and COBRA protein and homologues thereof as well as mutated alleles of COBRA. Also provided are anti-COBRA antibodies, transgenic plants which overexpress COBRA and methods for identifying COBRA modulating substances.

Abstract: The structure and function of a regulatory gene, WOODEN LEG (WOL), is described. The WOL gene is expressed specifically in the vasculature during early stages of embryogenesis with expression continuing throughout development. WOL encodes a novel two component signal transducer and is required for asymmetric cell divisions during vascular tissue morphogenesis. Also described are WOL nucleic acids, WOL gene products, (including, but not limited to, transcriptional products such as mRNAs, antisense, and ribozyme molecules, and translational products such WOL proteins, polypeptides, peptides and fusion proteins related thereto), antibodies to WOL gene products, WOL promoters and regulatory regions and the use of the foregoing to improve agronomically valuable plants.

Abstract: The structure and function of a regulatory gene, SHORT-ROOT (SHR), is described. The SHR gene is expressed specifically in root progenitor tissues of embryos, and in roots and stems of seedlings and plants. SHR 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 SHR gene, SHR-like genes, SHR gene products, (including but not limited to transcriptional products such as mRNAs, antisense, and ribozyme molecules, and translational products such the SHR protein, polypeptides, peptides and fusion proteins related thereto), antibodies to SHR gene products, SHR promoters and regulatory regions and the use of the foregoing to improve agronomically valuable plants.

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.

The invention relates to the SCR gene, SCR-like genes, 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.
