  • a The presence of a single gene is indicated by a closed circle. Where multiple genes are present, the number is given. −, absent.

  • b Searches for Atx1 using BLASTP and TBLASTN gave TBLASTN E values in marine Synechococcus and Prochlorococcus strains of >0.4, so Atx1 is either absent or looks completely different from ssr2857 of Synechocystis sp. strain PCC6803.
