Gene Details:

• Gene ID: Zm00001eb077580
• Gene Symbol: ZmNAC36 KIL1 nactf36
• Gene Name: KIRA1-LIKE1;NAC-transcription factor 36
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Loss of KIL1 function extends silk receptivity and thus strongly increases kernel yield following late pollination.
• KIL1 modulation is sufficient to extend or shorten the effective pollination period.
• KIL1 terminates fertility in maize by controlling silk senescence.
• KIRA1-LIKE1 (KIL1), an ortholog of the Arabidopsis NAC (NAM (NO APICAL MERISTEM), ATAF1/2 (Arabidopsis thaliana Activation Factor1 and 2) and CUC (CUP-SHAPED COTYLEDON 2)) transcription factor KIRA1, promotes senescence and programmed cell death (PCD) in the silk strand base, ending the window of accessibility for fertilization of the ovary.
• Loss of KIL1 function extends silk receptivity and thus strongly increases kernel yield following late pollination.
• The discovery of KIL1 is a first step toward understanding flower senescence in maize. Further exploring KIL1 functions may allow us to modulate maize fertility.
