Abstract
Free-living Sinorhizobium meliloti lpxXL and acpXL 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 of S. meliloti bacteroid lipid A with VLCFAs.
摘要
自由生活的苜蓿中华根瘤菌lpxXL和acpXL突变体缺乏脂多糖A的超长链脂肪酸（VLCFAs），并且在苜蓿中的竞争力降低。我们证明LpxXL和AcpXL在类菌体发育中发挥重要但不同的作用，并且LpxXL对于用VLCFAs修饰苜蓿中华根瘤菌类菌体脂多糖A至关重要。
