- BACKGROUND: Rice (Oryza sativa) is the most
important staple food of over half the world’s population.
This study was conducted to evaluate the possible impact of
transgenic rice cultivation on the soil microbial community.
METHODS AND RESULTS: Microorganisms were
isolated from the rhizosphere of GM and non-GM rice
cultivation soils. Microbial community was identified
based on the culture-dependent and molecular biology
methods. The total numbers of bacteria, fungi, and
actinomycete in the rhizosphere soils cultivated with GM
and non-GM rice were similar to each other, and there was
no significant difference between GM and non-GM rice.
Dominant bacterial phyla in the rhizosphere soils cultivated
with GM and non-GM rice were Actinobacteria, Firmicutes,
and Proteobacteria. The microbial communities in GM and
non-GM rice cultivated soils were characterized using the
denaturing gradient gel electrophoresis (DGGE). The
DGGE profiles showed similar patterns, but didn’t show
significant difference to each other. DNAs were isolated
from soils cultivating GM and non-GM rice and analyzed
for persistence of inserted gene in the soil by using PCR.
The PCR analysis revealed that there were no amplified
protox gene in soil DNA.
CONCLUSION(S): These data suggest that transgenic
rice does not have a significant impact on soil microbial
communities, although continued research may be necessary.
