Doctoral Thesis / Dissertation from the year 2014 in the subject Biology - Botany, grade: 4.00, Zhejiang University Of Science and Technology, course: College of Agriculture & Biotechnology, language: English, abstract: Plant growth-promoting rhizobacteria (PGPR) are free-living, soil-borne bacteria that colonize the rhizosphere and, when applied to crops, enhance the growth of plants, protect from disease and induce systematic resistance against abiotic stress. The present study was undertaken to estimate the potential use of rhizobacterial strains to control the bacterial brown stripe (BBS) caused by A. avenae subsp. avenae and brown sheath rot caused by P. fuscovaginae respectively, under in vitro and in vivo conditions, and study their potential mechanisms. In addition, a consortium of these two PGPRs and different chemical inducers were used to induce systematic resistance in rice plants against abiotic stress including cold and drought.
