Further, the level of changes in the transcripts exclusively induced in one or the other bacterium during infection of R. majalis was determined by quantitative real-time PCR (qRT-PCR) on following representative genes: cysK, def, dnaB, lysR, pchC, pckA, phoP, ptst1, sctL, selD, tolB and virB from P. temperata, and aceK, clpP, cobJ, dacC, dld, malF, res, rtxC, tilS, virH, xhlA, and xkst4 from X. koppenhoeferi. This evidence concerns the gene UTP25 and infection.
