摘要: 基于花生转录组及基因组数据,克隆获得一个花生的NBS-LRR类抗逆基因的全长序列,该基因与大豆抗病性蛋白基因(KHN40407.1)的相似性为79%,命名为AhNDrp基因。该基因不含内含子,cDNA 全长2 832 bp,有5个典型的抗逆性蛋白保守结构域,其中DomainⅤ是富含亮氨酸的重复序列。荧光定量PCR分析表明,AhNDrp基因在花生根中特异性表达,且黄曲霉处理后该基因表达量显著上升,说明该基因可能参与抗病反应。

Abstract: Based on peanut’s transcriptome and genome data,a full length sequence of NBS-LRR like-gene was cloned. This gene,which showed 79% similarity with disease resistance protein(KHN40407.1)of Glycine soja,was designated as AhNDrp gene. The length of cDNA of AhNDrp gene was 2 832 bp,and contained no intron. AhNDrp gene harbored 5 typical conserved domains with resistance-related protein,and Domain V was repeat sequence with rich leucine. Real-time quantitative PCR analysis showed that AhNDrp gene was expressed exclusively in root,and the expression was significantly increased after aflatoxin treatment,indicating that this gene was involved in the resistance response.

Key words: peanut, NBS-LRR gene, gene clone, expression analysis
