CC -!- FUNCTION: Transcriptional repressor that regulates lateral organ
CC polarity. Promotes lateral organ abaxial identity by repressing the
CC adaxial regulator ASYMMETRIC LEAVES2 (AS2) in abaxial cells. Required
CC for abaxial identity in both leaves and carpels. Functions with KAN2 in
CC the specification of polarity of the ovule outer integument. Regulates
CC cambium activity by repressing the auxin efflux carrier PIN1. Plays a
CC role in lateral root formation and development.

CC ECO:0000269|PubMed:15286295}.
CC -!- DEVELOPMENTAL STAGE: In globular embryos, expressed in the peripheral
CC cells in a basal region above the hypophysis. In heart-stage embryos,
CC expressed in the periphery of the presumptive hypocotyl and on the
CC abaxial side of cotyledon primordia. During vegetative growth,
CC expressed the abaxial side of very young leaf primordia. Expressed on
CC the abaxial side of carpel primordia and then in a localized region on
CC the abaxial margin that gives rise to the septum. Later, expressed in
CC the tissue that gives rise to ovules. {ECO:0000269|PubMed:11525739}.
CC -!- INDUCTION: Repressed by AS2 in adaxial tissue.
CC {ECO:0000269|PubMed:18849474}.
CC -!- DISRUPTION PHENOTYPE: Flat leaves. Altered morphology of abaxial
CC mesophyll cells. Decreased number of trichomes on the adaxial surface
CC and increased number of abaxial trichomes.
CC {ECO:0000269|PubMed:11395775, ECO:0000269|PubMed:11525739}.
CC -!- MISCELLANEOUS: Plants overexpressing KAN1 develop elongated and pointed
CC cotyledons and do not produced subsequent leaves, resulting in seedling
CC lethality.
