WebCis-acting elements - DNA sequences in the vicinity of the structural portion of a gene that are required for gene expression As we have mentioned several genes seem … WebTwo different cis-acting elements, a MYC-like sequence (CATGTG) and a 14-bp rps1 site 1-like sequence are necessary for dehydration induced expression of ERD1 (Simpson et al., 2003). Three NAC transcription factors; ANAC019, ANAC055, and ANAC072/RD26 were reported to bind MYC-like sequence present in the promoter of ERD1 (Tran et al., 2004).
