R gene diversity reading for Wednesday 9/17/14

 Last week we learned about how incompatibilities may arise due to epistasis between plant immune defense loci known as 'R genes.' We'd like to read more about where variation in R genes comes from, and get more background about what they do for plants. This week's paper looks at a specific R gene family in tomatoes, and makes some hypotheses about sources of selection acting on them.
