Microbial volatile organic compound 2,5-D enhances Arabidopsis growth through activation of nitrate and ammonium transport

ABSTRACT: Nitrogen is an essential nutrient for plant growth. We report here that 2,5-dimethylpyrazine is a key regulator of plant nitrogen and ammonium uptake through its regulation of AtNRTs and AtAMTs in the roots of Arabidopsis thaliana (Col-0) after 24 hours of exposure. In addition, 2,5-dimethylpyrazine encompassed plant hormone-related genes, such as SAURs and NRT2 family proteins, as well as defense-related transcription factors, including CNGCs, MAPK cascade, and WRKYs. Taken together, our data provide that 2,5-dimethylpyrazine is a potential candidate for promoting plant growth by regulating nitrate and ammonium transporters.
