Gene Details:

• Gene ID: Zm00001eb117870
• Gene Symbol: ZmDDM1A Chr101 Lsh1
• Gene Name: chromatin complex subunit A 101
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmDDM1A peaks were significantly overrepresented in 11 Pi and root developmental genes.
• Because Pi is a nutrient with limited mobility and is frequently disseminated in the soil surface, ddm1a’s phenotypic changes suggest that it is a likely model for low-Pi tolerance: ddm1a shows increased Pi uptake from the shallow soil layer through a shortened and thickened root system under low-Pi conditions.
• ZmDDM1A could bind to Pi- and root development-related genes.
• ZmDDM1A binds with genes related to Pi absorption and root development.
• ZmDDM1, as an important member of the RdDM pathway, can respond to low phosphorus stress by remodeling chromatin structure.
• 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.
