  1. The start and end positions according to the chromosomal or plasmid sequences in Genbank files (accessions NC_000911, AP004311 and AP004310), the location (S) on the forward (+) or reverse strand (−) and respective length (L; in amino acids) are given, followed by the locus tag ID, gene name and product if assigned. Location on chromosome or one of the plasmids is prefixed by “Chr” or the name of the plasmid. The existence of homologs in Synechocystis 6714, A. thaliana and E. coli is indicated by “Y” for yes or “N” for no. Homologs tagged and detected in this study are highlighted in boldface letters. Names of genes tested in this work are in boldface
