Estimating the term…
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.
An isolated nucleic acid molecule which hybridizes over its full length to the complement of the nucleic acid molecule of SEQ ID NO:1 under highly stringent conditions, wherein said highly stringent conditions consist of hybridization to filter-bound DNA in 0.5 M NaHPO4, 7% sodium dodecyl sulfate (SDS), 1 mM EDTA at 65° C., and washing in 0.1×SSC/0.1% SDS at 68° C., wherein said isolated nucleic acid molecule encodes a SCARECROW protein that has the property of SEQ ID NO:2 of directing the asymmetric division of the cortex/endodermal initial of a plant.
An isolated nucleic acid molecule wherein the nucleic acid molecule comprises SEQ ID NO:1.
An isolated nucleic acid molecule comprising a nucleic acid sequence that encodes a polypeptide comprising the amino acid sequence of SEQ ID NO:2.
