Gene Details:

  • Gene ID:
  • Gene Symbol: AhDMT1
  • Gene Name: Divalent Metal Transporter 1
  • Genome:
  • Species: Arachis hypogaea

Functional Descriptions:

  • AhDMT1, a Fe2+ transporter, is involved in improving iron nutrition and N2 fixation in nodules of peanut intercropped with maize in calcareous soils.
  • Identified AhDMT1 as a Fe2+ transporter which was highly expressed in mature nodules with stronger N2 fixation capacity. Promoter expression analysis indicated that AhDMT1 was localized in the vascular tissues of both roots and nodules in peanut.
  • Analysis of the correlation between the complex regulation pattern of AhDMT1 expression and iron nutrition status indicated that sufficient iron supply for long term was a prerequisite for keeping AhDMT1 at a high expression level in both, peanut roots and mature nodules.
  • Thus, the positive interspecific effect of intercropping may supply sufficient iron to enhance the expression of AhDMT1 in peanut roots and mature nodules to improve the iron nutrition and N2 fixation in nodules.
