Gene Details:

• Gene ID: Zm00001eb011780
• Gene Symbol: ZmCOI2a|coi4
• Gene Name: coronatine insensitive4
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmCOI2a|coi4 and ZmCOI2b redundantly regulate anther dehiscence and gametophytic male fertility in maize.
• ZmCOI2a|coi4 and ZmCOI2b, that redundantly regulate gametophytic male fertility. Both ZmCOI2a|coi4 and ZmCOI2b are highly homologous and constitutively expressed in all tissues tested. Subcellular localization revealed that ZmCOI2a|coi4 and ZmCOI2b were located in the nucleus.
• The coi2a coi2b double mutant, generated by CRISPR/Cas9, had non-dehiscent anthers, delayed anther development and MS. In addition, coi2a coi2b male gametes could not be transmitted to the next generation because of severe defects in pollen germination.
