Abstract
Rhizobium meliloti Rm1021 requires a Calcofluor-binding exopolysaccharide, termed succinoglycan or EPS I, to invade alfalfa nodules. We have determined that a strain carrying a mutation in the exoZ locus produces succinoglycan that lacks the acetyl substituent. The exoZ mutant nodules alfalfa normally.
摘要
苜蓿中华根瘤菌Rm1021需要一种与荧光增白剂结合的胞外多糖（称为琥珀聚糖或EPS I）来侵入苜蓿根瘤。我们已经确定，在exoZ基因座携带突变的菌株产生的琥珀聚糖缺乏乙酰取代基。exoZ突变体能够正常地使苜蓿结瘤。
