Gene Details:

• Gene ID: Zm00001eb055640
• Gene Symbol: ZmDDM1B Chr106
• Gene Name: chromatin complex subunit A 106
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmDDM1, as an important member of the RdDM pathway, can respond to low phosphorus stress by remodeling chromatin structure.
• ZmDDM1A and ZmDDM1B can regulate the expression of different downstream target genes through methylation.
• Mutation of ZmDDM1B, the homologous gene of ZmDDM1A, in maize did not lead to the same low-Pi tolerance phenotype.
• ZmDDM1A/ZmDDM1B double mutant caused embryo lethality with abnormalities in cell proliferation from the early stage of kernel development.
• ZmDDM1 may be recruited to euchromatic regions via recognition of a GC-rich motif, thereby remodeling chromatin to provide access for RdDM activities in maize.
