Gene Details:

• Gene ID: Zm00001eb269100
• Gene Symbol: ZmNRPC2 smk7
• Gene Name: small kernel7
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmNRPC2 affects RNAPIII activity and the expression of genes involved in cell proliferation and endoreduplication to control kernel development via physically interacting with RNAPIII subunits RPC53 and AC40, transcription factor class C1 and Floury3.
• We uncovered a regulatory pathway of ZmNRPC2 and its effects on maize kernel development.
• A frame shift in ZmNRPC2 leads to a premature stop codon, resulting in significantly reduced levels of transfer RNAs and 5S ribosomal RNA, which are transcribed by RNAPΙΙΙ.
• A regulatory pathway of ZmNRPC2 and its effects on maize kernel development.
• ZmNRPC2 Interacts with Subunits of the RNAPIII Complex and Regulates Expression of tRNAs and 5S rRNA.
