| Abstract: | Aims Arbuscular mycorrhizal fungi (AMF) can form symbiotic associations with most terrestrial plants to improve plant growth and stress resistance. It has been well demonstrated that AMF can promote plant acquisition of water and enhance plant tolerance to drought. In this study, AMF extraradical hyphae were obtained from in vitro culture of AMF Rhirophagus irregularis with hairy carrot (Daucus carota var. sativa) root to investigate the morphological and physiological changes of hyphae in response to drought stress induced by polyethylene glycol (PEG). |
