Abstract:
Limited information is available concerning the interactions between the brassinosteroid (BR) and auxin signaling pathways. The expression pattern of the SAUR‐AC1 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 SAUR‐AC1 gene is regulated by BRs independently of auxin levels, and that it is important in BR‐mediated elongation. The axr1 ( auxin insensitive 1 ) mutant was less sensitive to BL‐induced elongation and BL‐induced SAUR‐AC1 expression, suggesting that a ubiquitin ligase‐mediated system is involved in BR‐mediated elongation.
