The sweet potato gene SPF1 was the first WRKY gene to be cloned, followed by Arabidopsis thaliana (72), Oryza sativa (103), Solanum lycopersicum (81), and Zea mays (120) [16,17,18]. WebThe binding of a multisubunit RNA polymerase (RNAP) or general transcription factors to a specialized transcription promoter DNA sequence is an essential step in initiating DNA transcription in all organisms ( 1, 2 ). Control of this promoter binding step is a key mechanism by which gene expression is regulated ( 3 ).
