摘要: 以羽衣甘蓝(Brassica oleracea var. acephala)自交不亲和系(S13-b S13-b)为试验材料,利用RT-PCR的方法分离其ARC1基因cDNA序列(命名为BoARC1,GenBank登录号为EU344909)。BoARC1 cDNA序列中含有1个1 992 bp的开放读码框(ORF),编码1个含有663个氨基酸的蛋白质。羽衣甘蓝BoARC1与油菜BnARC1的氨基酸序列具有94%的一致性;Southern杂交结果显示BoARC1在基因组中只存在单一拷贝;Northern杂交结果显示BoARC1特异性地在柱头组织中表达;在酵母双杂交试验分析中,BoARC1能够与SRK3、SRK 13-b和SRK910的胞内激酶域发生相互作用。

关键词: 羽衣甘蓝, 自交不亲和, ARC1, 相互作用

Abstract: The ARC1 cDNA sequence was isolated from stigma of ornamental kale(Brassica oleracea var. acephala)S 13-b S 13-b homozygotes using RT-PCR techniques,named BoARC1(GenBank accession No. EU344909). The BoARC1 cDNA sequence had an ORF of 1 992 bp,encoding a 663-aa protein. The deduced amino acid sequence of isolated BoARC1 shared 94% identity with Brassica napus ARC1. Southern blot analysis showed that there was a single copy of BoARC1 gene in genome. Northern blot analysis showed that BoARC1 mRNA only expressed in the stigma. The yeast two-hybrid analysis indicated that the BoARC1 interacted with SRK3,SRK13-b and SRK910.

Key words: Brassica oleracea var. acephala, self-incompatibility, ARC1, interaction
