Study on bactetrial life strategy between forest and Antarctic soils.

16S rRNA sequencing technology was used to analyse the variation characteristics of soil bacterial weighted mean rRNA operon (rrn) copy number, structure, and functional potential. We expect to get the explanation of bacterial community life strategies and changes in structure and functions between Antarctic soils (lower resource conditions) and forest (temperate, subtropical, and tropical) soils (higher resource conditions).1. determine rrn copies of bacteria and their life strategies in Antarctic and forest (temperate, subtropical, and tropical) soils. 2.investigate bacterial community structure and function potentials in different soils.
