Summary
Dominant PHB mutations cause transformation of abaxial leaf fates into adaxial leaf fates. Encodes a member of HD-Zip family which contains homeodomain-leucine zipper domains and domain similar to a mammalian sterol binding domain. Has overlapping functions with PHAVOLUTA, REVOLUTA and CORONA.

Comments

Comment Type Description
Developmental Stage Expressed at the youngest stages of ovule development, predominantly to the adaxial side of the ovule primordium. Later, expression becomes restricted to a region in the distal chalaza. When the integuments initiate, expressed in the inner integument, with highest expression in the inner layer of the inner integument. Expressed in the vegetative shoot apical meristem (SAM) and initially throughout the presumptive cotyledons. At the globular stage, just before cotyledon outgrowth, expressed at high levels in cotyledon adaxial domains. Expression is lost from the SAM of torpedo stage embryos but is regained late in embryogenesis, extending to young primordia after germination, and becoming progressively restricted to the adaxial domain and the vasculature. Preferentially expressed in the adaxial domain of the developing leaf. Expressed throughout the plastochron 0 (P0) leaf primordium and expression increases in P1 to become preferentially localized to the adaxial leaf domain by the P2 stage (polar expression). {ECO:0000269|PubMed:11395776, ECO:0000269|PubMed:15328016}.
Function Probable transcription factor involved in the determination of adaxial-abaxial polarity in ovule primordium. Specifies adaxial leaf fates. {ECO:0000269|PubMed:11395776, ECO:0000269|PubMed:15328016, ECO:0000269|PubMed:15598805}.

Similarity Belongs to the HD-ZIP homeobox family. Class III subfamily. {ECO:0000305}.
Similarity Contains 1 homeobox DNA-binding domain. {ECO:0000255|PROSITE-ProRule:PRU00108}.
Similarity Contains 1 START domain. {ECO:0000255|PROSITE- ProRule:PRU00197}.
Subcellular Location Nucleus {ECO:0000305}.
Subunit Interacts with ESR1 and ESR2. {ECO:0000269|PubMed:17376809}.
