内容記述 | A R2R3-type MYB transcription factor, GAMYB, activates gibberellin inducible α-amylase gene transcription during cereal seed germination. Recent studies in several plant species suggested that the GAMYB also functions in other organs includes floral meristems, leaf, stem, flower, anther development, and floral transition. We isolated a GAMYB mutant in rice, designated GAMYBm. GAMYBm showed delay of germination, charasteristic dwarfism, partial defects of inflorescence formation and seed fertility and the OsGAMYB expression was decreased in GA-treated embryoless half seeds. Genomic and cDNA structure of the GAMYBm gene showed that multiple point mutations existed along genomic region of the OsGAMYB.R2R3タイプのMYB様転写因子のひとつであるGAMYBは、発芽期の単子葉穀類において、ジベレリン誘導型α-アミラーゼの転写を活性化する。最近の他の植物における最近の研究によって、GAMYBが発芽種子以外の他の器官、花芽分裂組織、葉、茎、花、葯の発生や花芽形成に機能する事が示唆されている。私たちは、イネにおけるGAMYB突然変異体、GAMYBmを単離した。GAMYBmは、発芽の遅延、特徴的な矮性、花序形成の部分的欠損を示し、ジベレリン処理を行った無胚半切種子におけるOsGAMYB mRNA蓄積量も低下していた。ゲノムDNAおよびcDNA構造の解析によって、GAMYBm遺伝子に複数の点突然変異が生じている事が明らかになった。 | |||||
