Table 1.
Distribution of chloroplast sensor kinases in photosynthetic eukaryotes. (A tick (√) indicates the presence and a cross (×) indicates the absence of ycf26 or CSK. A dash (—) indicates that the complete genome sequence for that taxon is not available, so the presence or absence of ycf26 or CSK is unknown. An asterisk (*) denotes that the occurrence is based on an earlier report (Duplessis et al. 2007). The taxonomic group ‘Viridiplantae’ means ‘green plants’, and includes green algae, lower plants and higher plants.)
