title: Endophytic bacteria in the rice plant.
abstract: Endophytic bacteria are defined as bacteria detected inside surface-sterilized plants or extracted from inside plants and having no visibly harmful effects on the plants. Various kinds of endophytic bacteria, such as Pantoea, Methylobacterium, Azospirillum, Herbaspirillum, Burkholderia and Rhizobium etc., have been found inside rice plants. This minireview summarizes and discusses recent studies of endophytic bacteria residing in rice plants, focusing on flora, origin, movement, and interaction with plants/other microbes and referring to endophytes in other plants. The findings concerning bacterial flora obtained by cultural and non-cultural methods are also compared and discussed. Some attempts to apply endophytes to the rice plant and the resultant effects are introduced. The future perspective to deepen the study of endophytes in terms of both application and basic science is considered.
