摘要: 以草莓(Fragaria ananassa Duch.)品种‘Darslect’的花药为试材,以MS培养基为基本培养基,进行愈伤组织的诱导。通过基因枪法将来源于大麦的胚胎发生晚期丰富蛋白基因LEA3 导入愈伤组织细胞,经过除草剂PFF的4次筛选培养,获得了抗性愈伤组织及再生植株。通过地高辛标记的探针进行Southern杂交分析,检测到了杂交带,表明LEA3 基因整合到草莓染色体基因组中。

Abstract: Callus of anther from strawberry (Fragaria ananassa Duch. Darslect) was induced on MS medium. Late embryogenesis abundant protein gene,LEA3,from barley(Hordeum vulgare L.)was introduced into strawberry callus by the aid of biolistic-mediated transformation method.After 4 times of PPI’selected culture. resistant calli and regenerated plants were obtained.The hybridization bands were determined in diferent transgenic plants by Southem blot,and this showed that LEA3 gene was integrated into strawberry genome.

Key words: Strawberry, Anther, Callus, LEA3 gene, Transformation
