Gene Details:

• Gene ID: Zm00001eb366170
• Gene Symbol: ZmRPABC5b Dek701
• Gene Name: defective kernel701
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmRPABC5b transcriptional regulatory network as a central hub for regulating endosperm development in maize.
• ZmRPABC5b, a common subunit to RNA polymerases I, II and III. Loss-of-function mutation of Dek701 impaired the function of all three RNA polymerases and altered the transcription of genes related to RNA biosynthesis, phytohormone response and starch accumulation.
• RNA polymerase common subunit ZmRPABC5b is transcriptionally activated by Opaque2 and essential for endosperm development in maize
• We cloned Dek701, which encoded ZmRPABC5b, a common subunit to RNA polymerases I, II and III. Loss-of-function mutation of Dek701 impaired the function of all three RNA polymerases and altered the transcription of genes related to RNA biosynthesis, phytohormone response and starch accumulation
• The results of this study provide substantial insight into the Opaque2–ZmRPABC5b transcriptional regulatory network as a central hub for regulating endosperm development in maize.
