Other claims from this paper (8)
- Observation Normal bean roots contained omega-hydroxy and dicarboxylic acids, dominated by C16 saturated and C18 monounsaturated homologues.
- Intervention effect Iron-deficient bean roots had 11% of control suberin aliphatic components.
- Intervention effect Iron deficiency did not significantly alter relative composition of suberin constituents.
- Intervention effect Iron deficiency decreased p-hydroxybenzaldehyde, vanillin and syringaldehyde in bean root suberin by 95%.
- Observation Omega-hydroxylation remained normal under iron deficiency in vitro and in situ.
- Intervention effect Iron deficiency suppressed suberization-associated peroxidase isozyme level to 25% of control roots.
- Intervention effect Iron status did not affect other extracted peroxidase isozymes.
- Mechanism Authors infer iron deficiency inhibits suberization through reduced isoperoxidase activity needed for aromatic-domain polymerization.
