Microorganisms including fungi and bacteria effect plant health and play important roles in crop production In ecosystems Volatiles emissions by microorganisms have been found to influence plant growth Volatiles produced by plant growth-promoting microorganisms have a positive impact on plant growth through direct stimulation or increase plant stress resistance This study isolated the fungi Tolypocladium sp GT22 with the ability to improve plant growth According to the results GT22 nearly doubles the fresh weight of Nicotiana benthamiana increases and the fresh weight of Arabidopsis thaliana by 70% Furthermore the interaction between GT22 and Brassica rapa chinensis was investigated to determine whether GT22 can be used for agricultural purposes The data indicates that it can significantly increase the fresh weight chlorophyll and carotenoids of Brassica rapa chinensis Gas chromatography-mass spectrometry (GC-MS) was used to separate and identify 40 kinds of Volatiles produced by GT22 Through investigation it was found that GTC is the critical compound which could improve plant growth Additionally Arabidopsis thaliana co-culture with GT22 conferred tolerance to arsenic stress and salt stress This research indicates that Volatiles of GT22 can promote plant growth and enhance plant abiotic stress tolerance
