Table 2.
Distribution of chloroplast response regulators and response regulator-like proteins in photosynthetic eukaryotes. (A tick (√) indicates the presence and a cross (×) indicates the absence of ycf27/ycf29/TCP34. A dash (—) indicates that the complete genome sequence for that taxon is not available, so the presence or absence of ycf27/ycf29/TCP34 is unknown. An asterisk (*) denotes that the occurrence is based on earlier reports (Weber et al. 2006; Duplessis et al. 2007). Chloroplast response regulators are mostly chloroplast gene products, but if the chloroplast response regulators exist as nuclear gene products, the nuclear location of the corresponding gene is indicated by a superscript N (N).)
