PXYLP1 and infection: Under non-inducing conditions, the xylP(p)::msgA strain was indistinguishable from wildtype, whereas on inducing medium the xylP(p)::msgA strain produced yeast cells that were rounder and greatly reduced in length compared to wildtype (Fig. 4B), resembling those produced by T. marneffei during J774 macrophage infection (Fig. 4B).
