One step in the production of transgenic cotton is the regeneration of whole plants from undifferentiated cells (calli) in which the gene of interest has been inserted.

This project was designed to assess the potential of a plant derived antifungal gene (NaD1) for control of cotton pathogens. The NaD1 gene codes for a small protein called a plant defensin.

Fusarium wilt continues to be an increasing problem in almost all major cotton growing regions of Australia.
