Post-transcriptional regulation of plant ferritin accumulation in response to iron as observed in the maize mutant ys1.
The maize mutant ys1 accumulates iron in leaves to a lower extent than a Fe-efficient genotype. In this mutant, ferritin mRNA accumulates in response to iron to a similar level as in other genotypes. However, ferritin protein and mRNA abundance does not correlate in ys1 leaves, demonstrating that iron also controls plant ferritin protein accumulation at the post-transcriptional level.
