Free-livingSinorhizobium meliloti lpxXL andacpXL mutants lack lipid A very-long-chain fatty acids (VLCFAs) and have reduced competitiveness in alfalfa. We demonstrate that LpxXL and AcpXL play important but distinct roles in bacteroid development and that LpxXL is essential for the modification ofS. meliloti bacteroid lipid A with VLCFAs.
