Gene Details:

• Gene ID: Zm00001eb361390
• Gene Symbol: ZmABI19 abi19 ZmAFL2
• Gene Name: ABI3-VP1-transcription factor 19
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The B3 domain-containing transcription factor ZmABI19 coordinates expression of key factors required for maize seed development and grain filling.
• ZmABI19 roles in coupling early endosperm and embryo development are also discussed.
• The results demonstrated that mutation of ZmABI19 causes profound defects in seed development and endosperm filling.
• ZmABI19 mutants displayed developmental defects in the endosperm and embryo, and mature kernels were opaque and reduced in size.
• The accumulation of zeins, starch and lipids dramatically decreased in ZmABI19 mutants.
• ZmABI19 directly regulates multiple key grain filling TFs including O2, Prolamine-box binding factor 1, ZmbZIP22, NAC130, and Opaque11 in the endosperm and Viviparous1 in the embryo.
