The endophyte Klebsiella pasteurii BDA134-6 isolated from African rice colonizes durum wheat plants helping them cope with water shortage stress.

ABSTRACT: Plant growth-promoting bacteria (PGPB) represents a sustainable strategy to improve the adaptability of plants to water shortage stress. The present study demonstrated that the endophyte Klebsiella pasteurii BDA134-6, isolated from O. glaberrima rice grown in Mali (West Africa), efficiently colonized the durum wheat variety Primadur. Results obtained from laboratory growth chamber, greenhouse phenotyping platform, and tunnel-type greenhouse demonstrated that inoculated Primadur plants improved their response to water shortage stress. When water shortage stress was simulated by treatment with polyethylene glycol, neither a significant decrease in the relative water content of leaves nor a strong inhibition of acetylene reduction was observed for inoculated plants compared to the uninoculate
