| 摘 要： | 番茄茸毛具有多种生物学功能,为了探究番茄中控制茸毛的基因,本研究采用cDNA末端快速扩增技术(rapid amplification of cDNA ends,RACE)从野生种多毛番茄(Solanumhabroc haites)LA1777中,获得了一个与茸毛相关的R2R3 MYB Subgroup 9家族新成员EST241733的全长编码区cDNA序列,命名为ShMYB1。经生物信息学分析,克隆的ShMYB1基因长1350bp,编码338个氨基酸。该基因具有保守的R2R3MYB结构域和Subgroup 9特异motif序列。荧光定量PCR结果表明,ShMYB1基因在番茄叶和花中表达量高,在根、茎、果实中没有表达。在不同发育时期的叶片中表达量差异不大,但是在幼花蕾表达量最高,随花蕾的增大,表达量显著降低。在几个番茄茸毛突变体与对应的野生型中,这个基因表达量存在明显差异。推测该基因与番茄表皮茸毛发生和花发育有关。 |

| Abstract: | The trichome has diverse biological functions in tomato,in order to explore the gene functions involved in trichome formation,a novel gene(named as ShMYB1) related trichome initiation was isolated from LA1777,using RACE(rapid amplification of cDNA ends) technology.The full-length sequence of ShMYB1 cDNA was 1 350 bp and encoded a protein of 338 amino acids.The ShMYB1 had a conserved R2R3 MYB domain and a specific subgroup 9 motif.The expression profiles of ShMYB1 were analyzed with Real-time PCR in differen... |
