摘要: 以短枝型富士苹果‘龙富短枝’(Malus × domestica Borkh.‘Longfu Duanzhi’)枝条为试材,
采用RT-PCR 结合RACE 技术,克隆获得苹果赤霉素受体基因MdGID1a,GenBank 基因数据库的登录号
为JF516247。该基因编码区共1 035 bp,推测其编码345 个氨基酸。氨基酸序列分析显示,其具有HSL
基因家族的保守氨基酸结构域HGG 和GXSXG,与其它植物赤霉素受体基因具有较高的同源性。其启动
子序列包含植物激素和光等响应元件。实时定量qRT-PCR 分析表明,MdGID1a 在短枝型‘龙富短枝’和
普通型‘长富2 号’枝条不同生长阶段、在叶片、枝条、果实、花和叶芽中的表达水平存在明显差异。
苹果赤霉素受体基因MdGID1a 在短枝型苹果枝条伸长过程中具有一定的调控作用。

Abstract: MdGID1a gene was amplified from spur-type apple(Malus × domestica Borkh.‘Longfu
Duanzhi’)shoots by using RT-PCR and RACE method. The sequence has been deposited in GenBank
database with the accession number of JF516247. The gene was named MdGID1a,containing an open
reading frame(1 035 bp)and encoding a protein of 345 amino acid. Sequence analysis indicated that
MdGID1a shared highly homology with HGG and GXSXG domain of HSL family gene. The promoter of
MdGID1a contained phytohormone and light regulatory elements. The real-time quantitative PCR analysis
showed that the expression levels of MdGID1a gene changed in different tissues,standard shoots andshoots of different growth stages. The GA receptor gene MdGID1a may play an important role during the
shoots development apple.

Key words: apple, GA receptor gene, gene expression analysis, promoter
