Abstract excerpt
The sequencing of multiple genomes of the same plant species has revealed polymorphic gene and exon loss. Genes associated with disease resistance are overrepresented among those showing structural variations, suggesting an adaptive role for gene and exon presence-absence variation (PAV). To shed light on the possible functional relevance of polymorphic coding region loss and the mechanisms driving this process,...
