Gene Details:

• MSU gene ID: LOC_Os12g01530
• RAPdb gene ID: Os12g0106000
• Gene Symbol: OsFER2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsFER2 mRNA levels in rice flag leaves and panicles at different reproductive stages were higher than OsFER1 mRNA levels.
• Exposure to copper, Paraquat, SNP and excess iron led to accumulation of ferritin mRNA, remarkably of OsFER2.
• OsFER2 expression is involved in rice resistance to M.
• The full-length ferritin OsFER2 and its transit peptide were localized to the chloroplast, the most Fe-rich organelle for photosynthesis.
• OsFER2 knock-out in wild-type rice HY did not induce ROS and ferric ion (Fe(3+)) accumulation, lipid peroxidation and hypersensitive response (HR) cell death, and also downregulated the defense-related genes OsPAL1, OsPR1-b, OsRbohB, OsNADP-ME2-3, OsMEK2 and OsMPK1, and vacuolar membrane transporter OsVIT2 expression.
• OsFER2 complementation in ΔOsFER2 knock-out mutants restored ROS and iron accumulation and HR cell death phenotypes during infection.
