The use of dominant mutations in the study of hormonal responses in plants


, : The use of dominant mutations in the study of hormonal responses in plants. Progress in plant growth regulation Proceedings of the 14th International Conference on Plant Growth Substances, Amsterdam, Netherlands, 21-26 July 1991: 28-33

In in vitro experiments, single gene mutants affecting hormonal responses provide a valuable tool in the refinement of otherwise very generalized models for the study of hormone signal transduction. A general model for hormone action, loosely based on known response pathways in microorganisms and animal systems, is described and the functioning of dominant hormone insensitive mutations (in Arabidopsis, dwf1, axr2, gai1, abi1 and etr1; wheat, Rht3; and maize, D8) outlined.

An analysis of how development time is specified by the heterochronic gene lin-4 to form a temporal development switch, and how other heterochronic genes regulate the lin-14 temporal switch in Caenorhabditis elegans is presented. This paper was gi...
