Visualization of the nucleolar ultrastructural change of common wheat induced by low concentration of actinomycin D
，-0001，（）：
Abstract. Common wheat root-tip meristematic cells were treated by low concentration of actinomycin D (ActD) and then "en bloc" stained by silver nitrate. It was showed under the TEM that typical nucleolar structure could not be formed but a granular and fibrillar composed network exhibited in the nucleolar region. Our result supports the opinion that there was really a relationship between nucleologenesis and the activation of RNA Polymerase (Poll) transcription. Furthermore, we infer that the network exhibited in the nucleolar region should be the nucleolar skeleton to support the nucleolus.
