5. Conclusion
Bathyarchaeia is highly abundant in most paddy soils across
eastern China, which is predominated by Bathy-6 . The abundance
and diversity of Bathyarchaeia vary considerably among different
soils. The relative abundance of Bathyarchaeia in paddy soils is
majorly regulated by the C/N ratio and MAT, whereas soil pH is the key
factor influencing Bathyarchaeia structure. Bathy-6 is
assembled mainly by deterministic progress with higher relative
abundance in high temperature, low C/N, and slightly acidic
environments. The network analysis revealed that Bathyarchaeiahelps in maintaining the stability of archaea community structure, with
high co-occurrence with methanogen and archaeal ammonia oxidizers. Our
results further elaborate our knowledge of Bathyarchaeia niche
differentiation. However, further research is required to reveal the
specific functions of these organisms in paddy soils.
