In the giant ciliate , oral apparatus (OA) regeneration is an experimentally tractable regeneration paradigm that occurs via a series of morphological steps. OA regeneration is thought to be driven by a complex regulatory system that orchestrates the temporal expression of conserved and specific genes. We previously identified a -specific gene (named ) that was significantly upregulated during the ciliogenesis stages of OA regeneration, with an expression peak at the stage of the first OA cilia appearance. We established a novel RNA interference (RNAi) method through cyanobacteria sp. PCC6803 feeding in . The expression of gene was significantly knocked down by using this method and induced abnormal ciliogenesis of OA regeneration in , suggesting that is essential for OA regeneration in . This novel RNAi method by cyanobacterial feeding has potential utility for studying other ciliates.
在大型纤毛虫中,口器(OA)再生是一种可通过一系列形态学步骤进行实验研究的再生模式。OA再生被认为是由一个复杂的调控系统驱动的,该系统协调保守和特定基因的时间表达。我们之前鉴定出一个特定基因(命名为 ),它在OA再生的纤毛发生阶段显著上调,在第一个OA纤毛出现阶段表达达到峰值。我们通过在 中投喂蓝藻PCC6803建立了一种新的RNA干扰(RNAi)方法。使用该方法 基因的表达被显著敲低,并在 中诱导了OA再生的异常纤毛发生,这表明 对 中的OA再生至关重要。这种通过蓝藻投喂的新型RNAi方法在研究其他纤毛虫方面具有潜在用途。
