Abstract
Streptomyces coelicolor A3(2) ftsI- and ftsW-null mutants produced aerial hyphae with no evidence of septation when grown on a traditional osmotically enhanced medium. This phenotype was partially suppressed when cultures were grown on media prepared without sucrose. We infer that functional FtsZ rings can form in ftsI- and ftsW-null mutants under certain growth conditions.
摘要
天蓝色链霉菌A3(2)的ftsI和ftsW缺失突变体在传统的渗透压增强培养基上生长时，产生的气生菌丝没有分隔迹象。当在不含蔗糖的培养基上培养时，这种表型会部分受到抑制。我们推断，在某些生长条件下，ftsI和ftsW缺失突变体中可以形成功能性的FtsZ环。
