Terpene Synthase gene neighborhood (one of two). On fosmid 41O22, two copies of the targeted TPS gene reside at gene sites 2 and 4, of which the gene site 2 sequence best matches that of the hybridization probe. Both TPS genes lack top-tier F-EST coverage. Each TPS gene has as its immediate neighbor a pentatricopeptide (PPR) gene (sites 1 and 3), constituting a tandem duplication of the TPS-PPR gene pair.
