Abstract excerpt
In Arabidopsis (Arabidopsis thaliana (L.) Heynh), exposure to volatile compounds (VCs) emitted by Penicillium aurantiogriseum promotes root hair (RH) proliferation and hyper-elongation through mechanisms involving ethylene, auxin, and photosynthesis signaling. In addition, this treatment enhances the levels of the small signaling peptide RAPID ALKALINIZATION FACTOR 22 (RALF22). Here, we used genetics to address...
