Abstract
How heterocyst differentiation is regulated, once particular cells start to differentiate, remains largely unknown. Using near-saturation transposon mutagenesis and testing of transposon-tagged loci, we identified three presumptive regulatory genes not previously recognized as being required specifically for normal heterocyst maturation. One of these genes has a hitherto unreported mutant phenotype. Two previously identified regulatory genes were further characterized.
摘要
一旦特定细胞开始分化，异形胞分化是如何被调控的，在很大程度上仍然未知。通过使用近饱和转座子诱变和对转座子标记位点的测试，我们鉴定出三个之前未被认为是正常异形胞成熟所特别需要的假定调控基因。其中一个基因具有迄今为止未报道过的突变表型。对两个之前已鉴定出的调控基因进行了进一步的表征。
