The paper generates the first genome sequence of a dioecious Solanum species and identifies the genetic basis of sex determination, finding males are the heterogametic sex and sex-specific genes are involved in pectin degradation.

The paper quantifies the risk of hemiplasy in phylogenetic inference by comparing its likelihood to homoplasy and introducing a method to calculate the hemiplasy risk factor across phylogenies.

The paper examines hybrid incompatibility by analyzing epistatic interactions between chromosomal regions in Solanum species, finding widespread antagonistic epistasis and its impact on hybrid sterility.

The paper identifies candidate genes involved in unilateral pollen-pistil reproductive barriers in Solanum habrochaites using transcriptomic analysis.
