ANT and AIL6: Masters of the master regulators during flower development

Abstract

The transcription factor AINTEGUMENTA (ANT) and its paralog AIL6, are important for early flower development. Knowledge of their direct target genes gives us a better understanding of this process. Using a genomewide ChIP-seq study, Krizek et al. (2021) investigated the DNA regions physically bound by the ANT or AIL6 protein in Arabidopsis. One of the key findings is that they directly regulate floral homeotic genes and genes related to growth and vasculature development in young flowers.
