Term Name:	RNA polymerase IV activity
Synonyms:	DNA-directed RNA polymerase activity involved in transcription from RNA polymerase IV promoter
Definition:	Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains an RNA polymerase IV specific promoter to direct initiation and catalyses DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
