Abstract Soil microbial communities are thought to be responsible
for the rhizosphere priming effect (RPE). However, because
soil microbial communities are comprised of diverse components,
very little is known about which component plays the critical role.
In this study, soybean and cottonwood were grown at two latitudinal
locations with different temperature and light conditions in-situ.
We quantified RPE using a natural δ13C method, and measured the
abundance, richness and composition of bacteria and fungi communities
with DNA-based molecular methods. Among all potential
variables, including the three aforementioned indexes of bacteria
and fungi communities and soil physicochemical and plant indexes,
bacterial abundance… More >
