The Regulator VasH Differentially Contributes to TfoX- and TfoY-Mediated T6SS Induction

(A) Scheme describing the TfoX-, TfoY-, and VasH-dependent regulation of the large and auxiliary T6SS gene clusters.

(B and C) The relative expression of genes of the auxiliary T6SS gene clusters 1 (B) and 2 (C) was determined by qRT-PCR. Bacteria were grown in the absence (−) or presence (+) of arabinose to induce tfoX (green)/tfoY (blue). Data are means of at least three independent biological replicates (±SD). Effector (E)/immunity (I) genes are highlighted by boxes.
