Gene Details:

• Gene ID: Zm00001eb235570
• Gene Symbol: ZmBT1
• Gene Name: brittle endosperm1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Dual Targeting to Mitochondria and Plastids of AtBT1 and ZmBT1, Two Members of the Mitochondrial Carrier Family.
• The patterns of GFP fluorescence distribution observed in plants stably expressing GFP fusions of ZmBT1 and AtBT1 N-terminal extensions were fully congruent with that of plants expressing a plastidial marker fused to GFP.
• Electron microscopic immunocytochemical analyses of maize endosperms using anti-ZmBT1 antibodies further confirmed that ZmBT1 occurs in both plastids and mitochondria.
• The overall data showed that (i) ZmBT1 and AtBT1 are dually targeted to mitochondria and plastids| (ii) AtBT1 and ZmBT1 N-terminal extensions comprise targeting sequences exclusively recognized by the plastidial compartment| and (iii) targeting sequences to mitochondria are localized within the mature part of the BT1 proteins.
