Conjugative transfer of bacterial plasmids to recipient cells is often mediated by type IV secretion machinery. Experimental investigations into the minimal gene sets required for efficient conjugative transfer suggest that such gene sets are variabl

We study a system of nonlinear Schrodinger equations with cubic interactions in one space dimension. The orbital stability and instability of semitrivial standing wave solutions are studied for both non-degenerate and degenerate cases.
