Signaling pathways underlying nitrogen transport and metabolism in plants

초록

Nitrogen (N) is an essential macronutrient required for plant growth and crop production. However, N in soil is usually insufficient for plant growth. Thus, chemical N fertilizer has been extensively used to increase crop production. Due to negative effects of N rich fertilizer on the environment, impro-ving N usage has been a major issue in the field of plant science to achieve sustainable production of crops. For that reason, many efforts have been made to elucidate how plants regulate N uptake and utilization according to their surround-ing habitat over the last 30 years. Here, we provide recent ad-vances focusing on regulation of N uptake, allocation of N by N transporting system, and signaling pathway controlling N responses in plants.
