CC -!- FUNCTION: Transcription factor required for normal cell
CC differentiation. Positively regulates LATERAL ORGAN BOUNDARIES (LOB)
CC within the shoot apex, and the class III HD-ZIP genes REV, PHB, and
CC PHV. Interacts directly with ASYMMETRIC LEAVES 2 (LBD6/AS2) to repress
CC the knox homeobox genes BP/KNAT1, KNAT2, and KNAT6 and the abaxial
CC determinants ARF3/ETT, KAN2 and YAB5. May act in parallel with the
CC RDR6-SGS3-AGO7 pathway, an endogenous RNA silencing pathway, to
CC regulate the leaf morphogenesis (PubMed:11076771, PubMed:11140682,
CC PubMed:11882937, PubMed:12750468, PubMed:16006579, PubMed:16699177,
CC PubMed:17395603, PubMed:17559509, PubMed:23271976). Binds directly to
CC KNAT1, KNAT2, and KNATM chromatin, regulating leaf development
CC (PubMed:23271976). LBD6 is required for this binding (PubMed:23271976).
CC Positive regulator of flowering that binds to the promoter of FT
CC (PubMed:21950734). Regulates FT expression by forming a functional
CC complex with CO (PubMed:21950734). Involved in leaf polarity
CC establishment by functioning cooperatively with NUCL1 to repress
CC abaxial genes ARF3, ARF4, KAN1, KAN2, YAB1 and YAB5, and the knox
CC homeobox genes KNAT1, KNAT2, KNAT6, and STM to promote adaxial
CC development in leaf primordia at shoot apical meristems at high
CC temperatures (PubMed:27334696). {ECO:0000269|PubMed:11076771,

CC -!- SUBUNIT: Homodimer (PubMed:12750468, PubMed:23271976). Heterodimer with
CC LBD6 (PubMed:23271976). Interacts with LBD6/AS2, HIRA, a probable
CC histone chaperone, and RIK, a predicted RNA binding protein
CC (PubMed:12874130, PubMed:16243907). Part of the AS1 repressor complex
CC composed of AS1, LBD6/AS2 and HDA6 (PubMed:23271976). Interacts with CO

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:23271976}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, stems, leaves, flowers,
CC siliques and in lateral organ promordia (PubMed:17559509). Found in the
CC inner domain between the adaxial and abaxial domains of leaves
CC (PubMed:17559509). Expressed in the phloem tissues of leaves,
CC cotyledons, hypocotyls, and roots (PubMed:21950734).
CC {ECO:0000269|PubMed:17559509, ECO:0000269|PubMed:21950734}.
CC -!- DEVELOPMENTAL STAGE: Preferential expression in young and immature
CC plant tissues. In embryos, expressed from the late globular stage
CC onwards. After germination, detected in leaf founder cells and on
CC flowering, in primordia of all floral organs.
CC -!- INDUCTION: Circadian-regulation with an afternoon peak in long days and
CC with a broad night peak in short days (PubMed:21950734). Expression of
CC AS1 in stem cells of the shoot apical meristem is prevented by SHOOT
CC MERISTEMLESS (STM). Expression is activated by GTE6 during leaf
CC morphogenesis (PubMed:16166385). {ECO:0000269|PubMed:16166385,
CC ECO:0000269|PubMed:21950734}.
CC -!- DOMAIN: A C-terminal domain (252-356) is required for dimerization.
CC -!- DISRUPTION PHENOTYPE: Plants with double mutations in this protein and
CC in RH10 or AS2 protein have abaxialized filamentous and trumpet-like
CC leaves at high temperatures. In double mutants, shapes of epidermal
CC cells of the filamentous leaves are simple and rectangular, similar to
CC those of a petiole, but different from those of flat leaves of wild-
CC type plants. {ECO:0000269|PubMed:27334696}.
