Abstract

âº Iron deficiency increased HA1, FRO2 and IRT1 gene expression in both CM and CC roots. âº IRT1 and IRT2 activities were higher in CC than in CM iron deficient roots. âº Enzyme activities and 57Fe root uptake rates confirmed genetic study. âº CM genotype accumulated a much larger pool of iron than CC in their root apoplast. âº FRO2 transcripts level and Fe3+ reducing activity determine Citrus iron tolerance.
