WebThe genetic analysis above suggested that NRT1.1, as a nitrate sensor, may somehow control the activity of CNGC15, a putative Ca 2+ channel, to couple the nitrate signal with the Ca 2+ second messenger. To perform such a function, NRT1.1 and CNGC15 should be in close proximity in the plasma membrane and may physically interact with each other. WebNitrate is both a nitrogen source for higher plants and a signal molecule regulating their development. In Arabidopsis, the NRT1.1 nitrate transporter is crucial for nitrate signaling governing root growth, and has been proposed to act as a nitrate sensor. However, the sensing mechanism is unknown.
