Gene Details:

• Gene ID: Zm00001eb273900
• Gene Symbol: KNR6
• Gene Name: KERNEL NUMBER PER ROW6
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Here, we show that a serine/threonine protein kinase encoding gene KERNEL NUMBER PER ROW6 (KNR6) determines pistillate floret number and ear length. Overexpression of KNR6 or introgression of alleles lacking the insertions of two transposable elements in the regulatory region of KNR6 can significantly enhance grain yield.
• KNR6 can interact with an Arf GTPase-activating protein (AGAP) and its phosphorylation by KNR6 may affect ear length and kernel number. This finding provides knowledge basis to enhance maize hybrids grain yield.
• Its phosphorylation by KNR6 may affect ear length and kernel number. This finding provides knowledge basis to enhance maize hybrids grain yield.
• Therefore, qKNR6 affects ear traits by regulating floret production by the ear inflorescence meristem.
• The haplotype 2 allele of KNR6 enhances hybrid grain yield.
