Abstract

The research will elucidate the role played by host-encoded factors in controlling the activity of the Ac-type transposons. The iae mutants of Arabidopsis display dramatic increases (approximately 550 fold in the case of iae1-1) in Ac activity (Plant J., 1997, 11: 907-919; Plant J., 1997, 11: 921- 931). The primary aim of the research will be to identify and characterise the IAE1 locus. The iae1 mutation maps to a genomic region which has been entirely sequenced, and so positional cloning will be greatly facilitated. The iae2 mutation will be mapped with a view to cloning the IAE2 locus in the future. Unpublished data suggest that the activities of other transposons related to Ac (Tag1 from Arabidopsis and Tam3 from Antirrhinum) are also elevated in iae1-1. Genetic and transgenic experiments to assess the effect of iae1 on these and other Ac-type elements will be conducted.
