Evolution of Type-C Response Regulators in Angiosperm and Specific Expression Pattern of SyGI.

Expression patterns of the orthologs/paralogs of SyGI gene in developing flowers (Fl) and in developing carpels (Ca) in D. lotus (Caucasian persimmon), V. corymbosum (blueberry), and A. chinensis (kiwifruit), all members of the Ericales order. SyGI was the only gene to exhibit strong expression in the carpels, suggesting that the ancestral gene was not expressed in the carpel and that SyGI acquired carpel (pistil) or flower expression specifically. The black circle labeled “d” indicates the node representing the SyGI-Achn384741 duplication.
