—Phylogeny-based scenario of nr-ACCase gene duplications in gymnosperms. ML trees of the four nr-ACCase proteins in gymnosperms. Numbers on the branches are bootstrap values (only >50% are shown). A blue diamond at the nodes indicates where a gene duplication event has occurred. The two duplicated gene copies are highlighted with pink and olive color shadings. The gene trees of heteromeric ACCase gene complex include (a) accA, (b) accB, and (c) accC. The homomeric ACCase (ACC) gene tree is depicted in (d).
