Characteristics of soil viral communities in Cunninghamia lanceolata plantations with different stand ages
We investigated the dynamics of soil viral community in Cunninghamia lanceolata plantations with dif-ferent stand ages(8,21,27,and 40 years old)in a subtropical region.The viral metagenomics and bioinformatics analysis were used to analyze the compositional and functional differences of soil viral communities across different stand ages,and to explore the environmental driving factors.The results showed that tailed phages dominated soil viral community in subtropical C.lanceolata plantations,with the highest proportion of Siphoviridae(19.6％-39.5％).There was significant difference in soil viral community structure among different stand ages,with the main driving factors being electrical conductance and available phosphorus.The metabolic functional genes encoded by viruses exhibited higher relative abundance.The α-diversity of soil viral function in mature C.lanceolata planta-tions was higher than other stands.There were significant differences in soil viral functional structure among differ-ent stand ages,which were mainly driven by ammonium nitrogen.During the development of C.lanceolata planta-tions,auxiliary metabolic genes encoded by virus related to nitrogen and phosphorus may regulate the metabolism of host microorganisms,thereby potentially impacting biogeochemical cycling of these elements.
