Brassica: Work in progress

Gene expression studies using EST arrays

• new coding sequences, novel genes
• gene array studies on expression - leads to promoter identification
• comparison of different types of defense responses
• fungi vs. bacteria
• specific resistance vs. basic resistance

Are there different kinds of basic resistance?
• systemic effects on gene expression

Through different combinations of small array of coding sequences and promoters, we can generate a diverse range of resistant genotypes.  A strategy of genetic engineering based on diversity may allow us to develop new resistance phenotypes more rapidly than pathogen populations can over come them.
