Zf-AD-containing C2H2 zinc -finger genes (ZAD) are uniquely present and have lineage-specific expansion in arthropods. Arthropods are also the hosts of Baculoviruses. We studied the possible relationship between the lineage-specific expansion of ZAD genes and arthropod-Baculovirus co-evolution. We used the silkworm (Bombyx mori) as a model. We identified 73 ZAD genes (BmZAD) in the silkworm. Sequence-based similarity analysis showed that nine clusters involving 28 BmZADs may have undergone species-specific expansion in the silkworm. Expression pattern analysis showed that the BmZADs were divided into five groups. Group I comprised 10 genes with high expression in multiple tissues, suggesting that BmZADs may play roles in the development of various tissues. We identified six BmZADs that could be induced by the Nucleopolyhedrovirus (BmNPV). Among them, BmZAD69 expression is capable of responding to BmNPV infection, and the ZAD domain is indispensable for the function of BmZAD69 in BmNPV replication. We also detected a 3 bp deletion at 1.7 kb upstream of BmZAD69, which may make it more sensitive to BmNPV infection, and thus elevate the BmNPV resistance in Qiufeng_N, a strain with strong virus resistance. These data suggest that BmZADs may be involved in BmNPV infection and that ZAD genes may play a role in arthropod-Baculovirus co-evolution.

含有 Zf-AD 的 C2H2 锌指基因对家蚕 BmNPV 复制的鉴定和影响 (Bombyx mori)

含有 Zf-AD 的 C2H2 锌指基因 (ZAD) 是独一无二的,并且在节肢动物中具有谱系特异性扩增。节肢动物也是杆状病毒的宿主。我们研究了 ZAD 基因谱系特异性扩增与节肢动物-杆状病毒共同进化之间的可能关系。我们使用家蚕 (Bombyx mori) 作为模型。我们在家蚕中鉴定了 73 个 ZAD 基因 (BmZAD)。基于序列的相似性分析表明,涉及 28 个 BmZAD 的 9 个簇可能在家蚕中经历了物种特异性扩增。表达模式分析表明,BmZADs 分为五组。第 I 组包含 10 个在多个组织中高表达的基因,表明 BmZADs 可能在各种组织的发育中发挥作用。我们确定了六种可以由核多角体病毒 (BmNPV) 诱导的 BmZAD。其中,BmZAD69 表达能够响应 BmNPV 感染,而 ZAD 结构域对于 BmZAD69 在 BmNPV 复制中的功能是必不可少的。我们还在 BmZAD69 上游 1.7 kb 处检测到 3 bp 缺失,这可能使其对 BmNPV 感染更敏感,从而提高了具有强病毒抗性的菌株 Qiufeng_N 的 BmNPV 抗性。这些数据表明 BmZADs 可能参与 BmNPV 感染,并且 ZAD 基因可能在节肢动物-杆状病毒共同进化中发挥作用。一种抗病毒能力强的菌株。这些数据表明 BmZADs 可能参与 BmNPV 感染,并且 ZAD 基因可能在节肢动物-杆状病毒共同进化中发挥作用。一种抗病毒能力强的菌株。这些数据表明 BmZADs 可能参与 BmNPV 感染,并且 ZAD 基因可能在节肢动物-杆状病毒共同进化中发挥作用。
