Gene Details:

  • Gene ID:
  • Gene Symbol: CitAMT1
  • Gene Name: ammonium transporter1
  • Genome:
  • Species: Citrus sinensis x Poncirus trifoliata

Functional Descriptions:

  • Ammonium transport and CitAMT1 expression are regulated by N in Citrus plants.
  • Citrus seedlings (Citrus sinensis L. Osbeck × Poncirus trifoliata Blanco) were used to describe the effects of different N treatments on the NH4 + influx mediated by high- and low-affinity transport systems (HATS and LATS, respectively) and CitAMT1 gene expression.
  • Furthermore, NH4 + exerts a regulatory effect on NH4 + HATS activity and CitAMT1 expression, both are down-regulated by high N status of the plant, but specifically stimulated by NH4 + and the balance between these two opposite effects depends on the prior nutrition regime of the plant.
  • Ammonium transport and CitAMT1 expression are regulated by light and sucrose in Citrus plants.
  • To explain this discrepancy, it is possible that other CitAMT1 transporters, up-regulated by N limitation, but not repressed by NO3 − could be involved in the stimulation of NH4 + HATS activity under pure NO3 − nutrition or CitAMT1 transporter could be regulated at the post-transcriptional level.
