Regulatory activity exerted by the SAUR-AC1 promoter region in transgenic plants

Plant Mol Biol. 1997 Jul;34(5):803-8. doi: 10.1023/a:1005875300606.


SAUR-AC1 is a small-auxin-up-RNA (SAUR) gene of Arabidopsis. Here we demonstrate that the SAUR-AC1 promoter region induces accumulation of a reporter transcript upon treatment with auxin and is preferentially active in elongating hypocotyls and certain other organs and tissues of transgenic Arabidopsis and tobacco plants. This study extends the utility of the SAUR-AC1 gene by providing a foundation for comparative analyses of SAUR promoter activity in auxin-responsive mutants of Arabidopsis.
