Bidirectional transcription from actin promoters in Dictyostelium.
Numerous transformation vectors for Dictyostelium discoideum have been constructed by fusing actin 6 and 15 promoters to selectable markers such as G418 and hygromycin. Strand specific probing of RNAs from transformed cells demonstrates that cells containing these vectors accumulate transcripts representing both strands of the vector. The evidence is consistent with bidirectional transcription initiating in the truncated actin promoter fragments. A larger fragment of the actin 15 promoter largely eliminates this problem.
