Ammonium Transporter (BcAMT1.2) Mediates the Interaction of Ammonium and Nitrate in Brassica campestris.

ABSTRACT: The provision of ammonium (NH₄ ⁺) and nitrate (NO₃ ^-) mixture increases the total nitrogen (N) than the supply of sole NH₄ ⁺ or NO₃ ^- with the same concentration of total N; thus, the mixture contributes to better growth in Brassica campestris. However, the underlying mechanisms remain unknown. In this study, we analyzed NH₄ ⁺ and NO₃ ^- fluxes using a scanning ion-selective electrode technique to detect under different N forms and levels in B. campestris roots. We observed that the total N influxes with NH₄ ⁺ and NO₃ ^- mixture were 1.25- and 3.53-fold higher than those with either sole NH₄
