摘要
以羽衣甘蓝(Brassica oleracea var.acephala)自交不亲和系(S13-bS13-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、SRK13-b和SRK910的胞内激酶域发生相互作用。
The ARC1 cDNA sequence was isolated from stigma of ornamental kal(e Brassica oleracea var.acephala)S13-bS13-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.
