The development of competence allowing natural transformation of Ralstonia solanacearum was found to occur during exponential growth and not in response to any excreted factors. Linear DNAs were effectively integrated by recombination requiring a minimum of 50 bp of homologous DNA. Therefore, DNA from other genera and species were ineffective.
人们发现,青枯雷尔氏菌自然转化能力的发展发生在指数生长期,并非对任何分泌因子的反应。线性DNA通过重组有效整合,这需要至少50 bp的同源DNA。因此,来自其他属和种的DNA无效。
