説明
<jats:p>Limited information is available concerning the interactions between the brassinosteroid (BR) and auxin signaling pathways. The expression pattern of the <jats:italic>SAUR‐AC1</jats:italic> gene, an early auxin‐inducible gene in Arabidopsis, was studied in response to brassinolide (BL), in the presence of a BR‐biosynthesis inhibitor, in a BR‐deficient mutant, and in combination with auxin. The results suggested that the <jats:italic>SAUR‐AC1</jats:italic> gene is regulated by BRs independently of auxin levels, and that it is important in BR‐mediated elongation. The <jats:italic>axr1</jats:italic> (<jats:italic>auxin insensitive 1</jats:italic>) mutant was less sensitive to BL‐induced elongation and BL‐induced <jats:italic>SAUR‐AC1</jats:italic> expression, suggesting that a ubiquitin ligase‐mediated system is involved in BR‐mediated elongation.</jats:p>
