摘要:

在以往研究苹果锈果类病毒ASSVd的基础上,以通过斑点杂交检测ASSVd为阳性的杏树为试验材料,利用RT-PCR技术扩增出苹果锈果类病毒全长特异片段,通过回收克隆测序,发现杏树苹果锈果类病毒基因组长为330nt,将克隆测序结果在GenBank中登录,获得10条序列,登录号为:EU031487-EU031496。在此基础上,利用原位RT-PCR检测技术,进一步证明杏树叶片中有苹果锈果类病毒存在,主要分布在细胞核中。该研究证实苹果锈果类病毒也能侵染杏树,丰富了苹果锈果类病毒的寄主。

Abstract:

Present study was conducted based on the previous research of Apple scar skin viroid (ASSVd) for apple and pear, used material of apricot was those that showed positive signal of blot hybridization detection. Full-length special fragment of ASSVd for apricot was amplicated using RT-PCR protocol, then was recycled, cloned and sequenced. It was demonstrated that the full-length genome of ASSVd of apricot is 330 nt long (GenBank numbered with EU031477 to EU031486). The exist of ASSVd in apricots was reconfirmed by the results of In situ RT - PCR , and ASSVd mainly located in nucleolus of mesophyll cell. The fact of infecting capability of apricot enlarged the host ranges of ASSVd.

Key words: apricot, Apple scar skid viroid, blot hybridization, RT-PCR, situ RT-PCR, full length analysis
