Fig. 6: The evolution of germacrene synthase genes in Zingiberaceous species.
From: Inversions encounter relaxed genetic constraints and balance birth and death of TPS genes in Curcuma
a Annotated functions of TPS genes in Zingiberaceous species in the NR (Non-Redundant Protein Sequence) database revealed that the annotated germacrene synthase genes were expanded in Curcuma. b Collinearity of tandem duplicated genes of germacrene synthase (blue) in C. petiolata and C. longa. c Germacrene synthase tandem duplication genes spanning inversions on C. petiolata chromosome 14 (Chr14). Inversions between haplotypes were marked in red. Germacrene synthase genes in the inversion were labeled blue. Black dots denoted the genes with the complete gene structure. d GC-MS analysis of the products from prokaryotic expression of intact germacrene synthases in Zingiberoideae species.
