| 英文摘要 | alginate oligosaccharides (aos), which are marine oligosaccharides, are involved in regulating plant root growth, but the promotion mechanism for aos remains unclear. here, aos (10-80 mg/l) induced the expression of auxin-related gene (osyucca1, osyucca5, osiaa11 and ospin1) in rice (oryza sativa l.) tissues to accelerate auxin biosynthesis and transport, and reduced indole-3-acetic acid (iaa) oxidase activity in rice roots. these changes resulted in the increase of 37.8% in iaa concentration in rice roots, thereby inducing the expression of root development-related genes, promoting root growth in a dose-dependent manner, which were inhibited by auxin transport inhibitor 2,3,5-triiodo benzoic acid (tiba) and calcium-chelating agent ethylene glycol bis (2-aminoethyl) tetraacetic acid (egta). aos also induced calcium signaling generation in rice roots. those results indicated that auxin mediated aos regulation of root development, and calcium signaling may act mainly in the upstream of auxin in the regulation of aos on rice root development.
