Results indicate that LEUNIG_HOMOLOG (LUH) functions with PHYTOCHROME-INTERACTING FACTOR1 (PIF1) as a transcriptional coregulator to inhibit seed germination.
Title: The Transcriptional Coregulator LEUNIG_HOMOLOG Inhibits Light-Dependent Seed Germination in Arabidopsis.
LUH is allelic to MUM1, and MUM2 is a likely target of LUH regulation. The transcriptional corepressor LEUNIG (LUG) is functionally interchangeable with LUH, raising the possibility that LUH functions as a repressor during seed coat maturation.
Title: The transcriptional regulator LEUNIG_HOMOLOG regulates mucilage release from the Arabidopsis testa.
that SLK1, SLK2 and LUH form a co-repressor complex.
Title: Involvement of co-repressor LUH and the adapter proteins SLK1 and SLK2 in the regulation of abiotic stress response genes in Arabidopsis.
LUH/MUM1 expression appears to be independent of other transcription factors known to regulate aspects of seed coat mucilage biology.
Title: The Arabidopsis transcription factor LUH/MUM1 is required for extrusion of seed coat mucilage.
luh-1 mutant seeds exhibit mucilage extrusion defects, but do not exhibit significant changes in seed coat morphology or integument cell differentiation.
Title: LEUNIG_HOMOLOG and LEUNIG regulate seed mucilage extrusion in Arabidopsis.
YABs interact with LUG and LUH. Together these proteins maintain leaf polarity and meristem activity in Arabidopsis.
Title: YABBYs and the transcriptional corepressors LEUNIG and LEUNIG_HOMOLOG maintain leaf polarity and meristem activity in Arabidopsis.
