Gene Details:

• Gene ID: Zm00001eb360520
• Gene Symbol: Ig2
• Gene Name: indeterminate gametophyte2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Indeterminate gametophyte2 encoding a MICROTUBULE ASSOCIATED PROTEIN65-3 homolog, shows a requirement for MAP65-3 in cellularization of the syncytial embryo sac as well as for normal seed development.
• The timing of the effects of Ig2 suggests that the identity of the nuclei in the syncytial female gametophyte can be changed very late before cellularization.
• Ig2 mutants produce extra polar nuclei but through defects in embryo sac cellularization rather than through an excess of free nuclear divisions.
