Nitrogen is an essential macronutrient for plants and its availability is a major limiting factor for plant growth and crop production. Nitrate is the main source of inorganic N for plants in aerobic soils and can act as a potent signal to control global gene expression. We found that gene expression in response to nitrate treatment of the AFB3 auxin receptor and its target, the NAC4 transcription factor depends on the nitrate transport function of NRT1.1. This gene regulatory function of NRT1… CONTINUE READING
