^a Sequences for E. amylovora TCST genes are from the whole genomic sequence of E. amylovora http://www.sanger.ac.uk/Projects/E_amylovora/. One TCTS system (ypdAB) in E. tasmaniensis is not present in E. amylovora Ea273. Two sets of CheABRWYZ exist in E. amylovora, but only one set in E. tasmaniensis.
^b In parentheses is gene or gene number for the corresponding gene in E. tasmaniensis.
^c The number in parentheses is the length of deduced amino acid for the corresponding protein in E. tasmaniensis which differs from those in E. amylovora.
^d All data are the highest aa similarity and identify found in NCBI database as of today except for HrpXY which share the highest aa identity/similarity to those in E. pyrifoliae (98/99%; 99/99%, respectively). N/A: not available.
