This difference might be due to the variety of rice, environmental parameters of rice cultivation, and plant
genotype. The plant genotype affects the colonization and nutrient status of bacterial communities associated with the
plant (Van Overbeek and Van Elsas 2008; Hardoim et al. 2011). According to Engelhard et al. (2000), the diazotrophic
endophytic diversity was greater in modern rice cultivars than in wild rice.
