| 摘要 |
The active portion of a trans-activating factor, TAF-1, has been identified, isolated and characterized. This proteinaceous factor binds to motif-I-like sequences previously identified within numerous plant promoter elements. TAF-1 may be engineered into cell culture systems or transgenic plants to increase or modulate the expression of heterologous genes fused to promoter elements containing one or more copies of cis-acting sequences known to bind TAF-1.
