^aLocus number, putative identification, and cellular role are according to the TIGR genome database.

^bAverage fold difference indicates the expression of the gene by polyP addition versus no polyP addition.

^cThe cut off ratio for the fold difference was < 1.5.

^dPutative identification and cellular role are according to Lewis [24].
