dc.description.abstractIt is known that volatile emissions from some beneficial rhizosphere microorganisms promote plant growth. Here we show that volatile compounds (VOCs) emitted by phylogenetically diverse rhizosphere and non-rhizhosphere bacteria and fungi (including plant pathogens) promote growth and flowering of various plant species, including crops. In Arabidopsis plants exposed to VOCs emitted by the phytopathogen Alternaria alternata, changes included enhancement of photosynthesis and accumulation of high levels of cytokinins (CKs) and sugars. Evidence obtained using transgenic Arabidopsis plants with altered CK status show that CKs play essential roles in this phenomenon, since growth and flowering responses to the VOCs were reduced in mutants with CK-deficiency (35S:AtCKX1) or low receptor sensitivity (ahk2/3). Further, we demonstrate that the plant responses to fungal VOCs are light-dependent. Transcriptomic analyses of Arabidopsis leaves exposed to A. alternata VOCs revealed changes in the expression of light- and CKresponsive genes involved in photosynthesis, growth and flowering. Notably, many genes differentially expressed in plants treated with fungal VOCs were also differentially expressed in plants exposed to VOCs emitted by the plant growth promoting rhizobacterium Bacillus subtilis GB03, suggesting that plants react to microbial VOCs through highly conserved regulatory mechanisms.es_ES
