Abstract
We propose to investigate whether there are changes in gene expression when roots of rice plants encounter mechanical impedance. A sand core system will be used so that mechanical impedance can be varied independently of aeration and water status. Plants of genotypes known to be tolerant of susceptible to mechanical impedance will be grown under control and impeded conditions and changes in gene expression studied in the different tissues using cDNA-AFLP, differential display and subtractive hybridisation techniques. The work will increase understanding of impedance and so improve physiological screens; and provide DNA sequences both for the screening of young plants and for the future production of transgenic crops.
