Glutamine-Induced Root Hair Elongation Depends on Ethylene Signalling and the RHD6 Regulatory Pathway.
Glutamine (Gln), the first organic nitrogen (N) produced during primary N assimilation, is increasingly recognised as a signalling molecule in plants. Here, we show that Gln, supplied as the sole N source, promotes root hair elongation in Arabidopsis seedlings compared with NH4NO3. This response is dose-dependent and p...
