Autotrophic bacteria containing cbbL
|
Gammaproteobacteria was the main class.
The correlation between relative abundance and soil salinity was
positive and significant.
|
Gammaproteobacteria was the main class.
In moderate and low salinity soils, Betaproteobacteria and
Alphaproteobacteria also had large relative abundance.
|
Community diversity and richness: NR > R.
Relationship between relative abundance and pH: negative correlation
(r<-0.6).
Soil environments with sufficient oxygen and low CO2
concentration were conducive to survival.

Autotrophic bacteria containing cbbM
|
Gammaproteobacteria and Alphaproteobacteria were the
main classes.
Relationship between relative abundance of Betaproteobacteria
and salinity: significant negative correlation.
|
Betaproteobacteria and Alphaproteobacteria were the main
classes.
Relationship between relative abundance of Gammaproteobacteria
and salinity: significant negative correlation.
|
Community diversity and richness: R > NR.
Relationship between relative abundance and pH: negative correlation
(r<-0.5).
Soil environments with low oxygen and high CO2
concentration were conducive to survival.

classes.
Relationship between relative abundance and salinity: significant
negative correlation.
|
Community diversity and richness: R > NR.
