that complexes of the transcription factors ASYMMETRIC LEAVES 1 (AS1) and AS2 could help to establish the H3K27me3 modification at the chromatin regions of Class-I KNOTTED1-like homeobox (KNOX) genes BREVIPEDICELLUS and KNAT2 via direct interactions with LHP1.
Title: Transcription factors AS1 and AS2 interact with LHP1 to repress KNOX genes in Arabidopsis.

critical for the proper placement of the floral organ abscission zones, and influences the timing of organ shedding
Title: ASYMMETRIC LEAVES1 regulates abscission zone placement in Arabidopsis flowers.

Negative transcriptional, post-transcriptional and epigenetic regulation of ARF3 by AS1-AS2 is important for stabilizing early leaf partitioning into abaxial and adaxial domains.
Title: Dual regulation of ETTIN (ARF3) gene expression by AS1-AS2, which maintains the DNA methylation level, is involved in stabilization of leaf adaxial-abaxial partitioning in Arabidopsis.

The JLO and AS2 proteins interact molecularly and form multimeric complexes with AS1 to suppress KNOX expression. AS2 together with JLO regulate auxin transport in seedling roots.
Title: Arabidopsis JAGGED LATERAL ORGANS acts with ASYMMETRIC LEAVES2 to coordinate KNOX and PIN expression in shoot and root meristems.

Taken together, these data indicate that HDA6 is a part of the AS1 repressor complex to regulate the KNOX expression in leaf development.
Title: Histone deacetylase HDA6 is functionally associated with AS1 in repression of KNOX genes in arabidopsis.
