| 摘 要： | The physiological phenotype of the rice semi-dwarf mutant,sdg,was characterized in details using a pair of near isogenic .Neither gibberellin*deficient nor gibberellin-insensitive is characteristic of the sdgphenotype.Byanalyzing the secretion of aamylas and the promotion of stem growth caused by eogenous gibberellin(GA),the sdg plant was found to have decreased sensitivity to the GA at the seedling stage. The dwarfism stature of the sdg mutant can be attributed to the shortened internodes. Increase of the cell sults indicate the protein encded by the wild type gene of sdg may be a regulator for cell elogation. |
