The aggregation phenotypes Agr+ and Agr- of Bacillus thuringiensis subsp. israelensis are correlated with a conjugation-like plasmid transfer and characterized by the formation of aggregates when the bacteria are socialized during exponential growth. We present evidence for the association of the Agr+ phenotype with the presence of the large (135-MDa) self-transmissible plasmid pXO16.
苏云金芽孢杆菌以色列亚种的Agr+和Agr-聚集表型与类似接合的质粒转移相关,其特征是当细菌在指数生长期间群体化时形成聚集体。我们提供了证据,证明Agr+表型与大的(135-MDa)自我传递性质粒pXO16的存在有关。
