indicated that this isolate was able to colonize rice roots. Similar results of bacterial
colonization in rice roots have been reported (Etesami et al. 2014; Qin et al. 2017).
This root colonization is an important factor in both plant growth-promoting activities
and the survival of bacteria under drought conditions(Gontia-Mishra et al. 2016).
