Morphological mutants of Caulobacter crescentus were isolated by selecting for cells that did not possess normal, buoyancy-conferring stalks. The most prevalent phenotype enriched by the selection was structurally deficient stalks (designated "Cds"), observable as crumpled or flattened stalks. The second phenotype ("Abs") was observed as spontaneous shedding of normal-appearing stalks. Third, one mutant ("Ecs") was isolated that sheds not only stalks, but also miniature stalked and nonstalked cells.
通过筛选不具有正常的、赋予浮力的柄的细胞，分离出了新月柄杆菌的形态突变体。通过该筛选富集的最常见表型是结构缺陷的柄（称为“Cds”），可观察到皱缩或扁平的柄。第二种表型（“Abs”）表现为外观正常的柄的自发脱落。第三，分离出了一种突变体（“Ecs”），它不仅会脱落柄，还会脱落带微型柄和不带柄的细胞。
