Abstract

Two possible mechanisms are considered for the occurrence of experimentally or genetically induced duplications of bristles: extra cell division of a bristle mother cell versus determination of more than one mother cell. From a clonal analysis it appears that duplications induced by actinomycin-D arise by the latter mechanism, whereas those found in the mutantspl seem to arise by the former mechanism.

摘要

对于实验诱导或基因诱导的刚毛重复出现，考虑了两种可能的机制：刚毛母细胞的额外细胞分裂与不止一个母细胞的确定。从克隆分析来看，放线菌素D诱导的重复似乎是由后一种机制引起的，而在突变体spl中发现的重复似乎是由前一种机制引起的。
