柑桔MADS盒APETALA1同源DNA片段克隆

Cloning DNA Fragment of APETALA 1 Homologue of the Citrus MADS box

用PCR扩增法 ,从柑桔基因组分离出了AP1同源基因中的一个片段。序列分析表明 ,它与其它植物的MADS盒基因同源性较高 ,氨基酸序列同源 4 5%～ 73% ,但是否与发育有关 。

Through PCR method,a fragment of AP 1 homologue is separated from citrus gene library of DNA.This fragment is conserved with MADS box genes in other plants.The amino acid sequence deduced from the exons is 45%-73% homologous to that of the corresponding regions of MADS box genes in other plants.This fragment is appeared at GenBank.Serial number is AF 2639911.
