Gene Details:

  • Gene ID:
  • Gene Symbol: LeIRT1
  • Gene Name: iron-regulated transporter 1
  • Genome: Tomato Genome version SL4.0
  • Species: Solanum lycopersicum

Functional Descriptions:

  • LeFRO1 encoding an Fe(III)-chelate reductase protein was isolated from the tomato genome. We show that expression of LeFRO1 in yeast increases Fe(III)-chelate reductase activity. In a transient expression analysis we found that LeFRO1 protein was targeted on the plasma membrane.
  • The differential expression of LeFRO1 and LeIRT1 (an iron-regulated metal transporter gene in tomato) in roots of T3238fer under iron-deficient and -sufficient conditions suggests that the FER gene may regulate expression of LeFRO1 more directly than that of LeIRT1 in tomato roots.
  • The growth defect of an iron uptake-deficient yeast (Saccharomyces cerevisiae) mutant was complemented by LeIRT1 and LeIRT2 when ligated to a yeast expression plasmid.
  • The enhanced expression of LeFRO1, LeIRT1 and LeNRAMP1 under the culture condition with high pH or on agar media with NO(3) (-) as the sole N source might be a consequence of reduced iron availability in the solution or agar medium at high pH.
