  • Kuuluvad rohkearvulisse taimespetsiifiliste hormoonide signaalahelates osalevate NAC tüüpi transkriptsioonifaktorite rühma, mis mõjutavad pealmaaosade (võsu tipumeristeem, õiealgmed, külgvõrsed) arengut. Nende geenide topeltmutandid moodustavad kokkusulanud idulehtedega tassikujulisi embrüoid. Soodustavad transkriptsioonifaktori STM (shoot meristemless) ekspresseerumist, mis pärsib lehealgmeid spetsifitseerivad geenid ja tekitab kahte idulehe alget eraldava piirkonna.
  • Belong to the large family of NAC-type transcription factors that are involved in the development of plant's above-ground parts (shoots, flowers). Homozygous mutants develop morphed, cup-like embryos. They induce the expression of transcription factor STM (shoot meristemless) that suppress the genes responsible for leaf development.
