Description:
AbstractThe Arabidopsis (Arabidopsis thaliana L.) genome encodes for four distinct classes of homeodomain leucine‐zipper (HD‐ZIP) transcription factors (HD‐ZIPI to HD‐ZIPIV), which are all organized in multi‐gene families. HD‐ZIP transcription factors act as sequence‐specific DNA‐binding proteins that are able to control the expression level of target genes. While HD‐ZIPI and HD‐ZIPII proteins are mainly associated with environmental responses, HD‐ZIPIII and HD‐ZIPIV are primarily known to act as patterning factors. Recent studies have challenged this view. It appears that several of the different HD‐ZIP families interact genetically to align both morphogenesis and environmental responses, most likely by modulating phytohormone‐signaling networks.
