Abstract Aims The volatile organic compounds (VOCs) produced by soil microbes modulated plant growth and development. Floccularia luteovirens, an edible mushroom, is beneficial to the growth of alpine meadow plants on the Qinghai-Tibet Plateau. We aimed to elucidate the physiological and molecular mechanisms underlying the mushroom fungal VOC-mediated plant growth and development. Methods Here, we investigated the effects of VOCs produced by F. luteovirens on the root system development and seedling growth by integrating physiology,
genetics, transcriptome and metabolome analysis using 1/2 MS medium-grown Arabidopsis thaliana seedlings. Results Treatment with F. luteovirens VOCs reduce primary root growth by aggravating auxin accumulation through the repression of the abundance of auxin efflux carrier PIN-FORMED 2 (PIN2) protein, whereas it increases the lateral root number of A. thaliana seedlings. In addition to modulating root system architecture, treatment with F. luteovirens VOCs markedly increased aboveground growth. The transcriptome and metabolome analyses further supported the notion that F. luteovirens VOCs modulate plant growth and

Conclusions These results suggested that application of F. luteovirens VOCs promote growth by inducing changes in root system architecture through auxin pathway and regulating metabolism in plants.
