Abstract

Viruses are ubiquitous and ecologically important, but fewer information is available for heritage. In this report, we analyzed the taxonomy and metabolic potentials of viruses on three globally renowned monuments, namely Angkor Wat (AW), Bayon Temple (Bayon Temple Entrance, BTE), Bayon temple Gallery No. 25 (BayonG25), and Preah Vihear (PV) in Cambodia by metagenomic sequencing and analysis. Virus species characterization results show that vast majority of them on these stone cultural heritage are unclassified, with a tiny small fraction affiliated with Siphoviridea. Results of auxiliary metabolic genes (AMGs) analyses revealed a wide range of metabolic potentials of these viruses, with cofactor and vitamin metabolism being detected at all sampling sites, suggesting that viruses may play an important role in the microbial biofilm formation, development and energy metabolism.

在柬埔寨吴哥窟、巴戎和柏威夏的砂岩纪念碑上的病毒群落
病毒无处不在,具有重要的生态意义,但可用于遗产的信息较少。本文采用宏基因组测序和分析方法,对柬埔寨吴哥窟(Angkor Wat, AW)、巴戎寺(Bayon Temple Entrance, BTE)、巴戎寺25号廊(BayonG25)和柏威hear (PV) 3个世界著名古迹的病毒进行了分类和代谢潜力分析。病毒种类鉴定结果表明,这些石质文化遗产上绝大多数病毒未分类,只有极小部分隶属于Siphoviridea。辅助代谢基因(AMGs)分析结果显示,这些病毒具有广泛的代谢潜力,在所有采样点都检测到辅助因子和维生素代谢,这表明病毒可能在微生物生物膜的形成、发育和能量代谢中发挥重要作用。
