“Background Plants interact with a great diversity of microorganisms, including enteric bacteria. These interactions, which are governed by the characteristics of both Etomidate host plant and bacteria, result in either commensalistic, mutualistic or parasitic relationships between both partners. In rice, bacterial endophytes may provide support to the host plant when these are under Ilomastat stress conditions [1, 2]. For instance, rice growth under conditions

of low temperature, high salinity or desiccation may be favored. Moreover, endophytes can supply nitrogen to rice tissues [3]. In previous work, different bacteria, in particular belonging to the enterics, have been isolated from rice seeds [4, 5], roots [3, 6] and stems [7]. For example, Enterobacter cloacae subsp. dissolvens, previously described as Erwinia dissolvens, was first isolated from diseased corn [8], whereas it was also found in the endosphere of rice plants without causing apparent harm to the host plant [9]. Enterobacter cancerogenus NCPPB 2176T, E. nimipressuralis ATCC 9912T and E. pyrinus ATCC 49851T were isolated from symptomatic necrosis sites, respectively from poplar, elm and pear trees [8, 10, 11]. These organisms are therefore known as phytopathogens. On the other hand, organisms such as E. radicincitans D5/23T, E. arachidis Ah-143T, E. oryzae Ola-51T and Enterobacter sp. CBMB30, which have been isolated from respectively the phyllosphere of wheat, the rhizosphere of groundnut and the endosphere of rice species (i.e.
