There are two primary purposes for "Evolving Resistance in the Solanaceae".
First, the results of evolutionary analyses for resistance genes sequences in
species of the Solancaeae are displayed. The study focuses on NBS-LRR genes
related to I2, the Fusarium resistance locus of tomato located on chromosome 11.
We examined I2-homologs (I2-h) in six species within the Solanaceae to determine
'residence times' of lineages, the extent to which I2-h gene copies are maintained
over time in these genomes. Second, we want the site to facilitate the use of
evolutionary information in identifying genes of value for crop improvement.
Specifically, the rationale is that genes providing more 'durable' resistance
will be maintained through speciation events and will be conservative in their evolution.
