Abstract

Very recently we have identified tomato mutants that are insensitive to the plant steroid hormone brassinolide (BL) and are defective in tBRI1, the tomato homolog of BRASSINOSTEROID INSENSITIVE 1 (BRI1). tBRI1 (SR160) has also been isolated via binding to the plant peptide hormone systemin that is involved in wound signalling. To clarify the role of tBRI1/SR160 in systemin signalling we will carefully assay our unique collection of tomato BL mutants for response to systemin and wounding. We will also determine the key residues in tBRI1 that are essential for systemin and BL signalling by generating and assaying lines harbouring chimaeric receptors between BRI1 homologs from species that do and do not perceive systemin. Our results will therefore provide key knowledge that will aid the generation of crops with enhanced growth and wound resistance characteristics.
