Abstract

Paddy fields include two interconnected ecosystems—soil and floodwater. Microbes and viruses are an integral component of these ecosystems, yet the viral communities have not been extensively studied. We present an analysis of the viromes of paddy floodwater collected during the two cropping seasons in India, the kharif and rabi seasons respectively. The overall taxonomic and functional characteristics appeared to be similar in both seasons, suggesting stability of the viral community. Taxonomically, the families of tailed bacteriophages dominated. The predominance of functional roles related to lytic phages further confirmed this. We reconstructed two complete and several partial viral genomes from the assembled data. The genomes did not align with any known sequences, thus representing novel viruses of the floodwater ecosystem.

两季稻田洪水的病毒组分析
稻田包括两个相互关联的生态系统--土壤和洪水。微生物和病毒是这些生态系统不可或缺的组成部分,但病毒群落尚未得到广泛研究。我们对分别在印度的两个耕种季节(旱季和涝季)收集的稻田洪水病毒组进行了分析。两个季节的总体分类和功能特征似乎相似,这表明病毒群落具有稳定性。从分类学角度看,有尾噬菌体家族占主导地位。与裂解噬菌体有关的功能作用占主导地位进一步证实了这一点。我们从收集到的数据中重建了两个完整的病毒基因组和几个部分病毒基因组。这些基因组与任何已知序列都不一致,因此代表了洪水生态系统中的新型病毒。
