摘要野生型或hetC鱼腥藻的无氮花丝。以半规则的间隔分别产生异形胞和弱荧光细胞。与异形囊不同，后者的细胞可以分裂和伸长，产生一系列间隔的小细胞模式。由于ahetR：：GFP融合在小细胞中表达最强，我们认为这些小细胞代表了异形囊分化的早期阶段。hetC：：GFP在前异形囊和异形囊中表达最强。
ABSTRACT Nitrogen-deprived filaments of wild-type or hetC Anabaena sp. produce respectively, at semiregular intervals, heterocysts and weakly fluorescent cells. Unlike heterocysts, the latter cells can divide and elongate, producing a pattern of spaced series of small cells. Because ahetR::gfp fusion is expressed most strongly in the small cells, we propose that these small cells represent a very early stage of heterocyst differentiation.hetC::gfp is expressed most strongly in proheterocysts and heterocysts.
