Transcription profiling of Arabidopsis wild type, FIE- and MIA- loss-of-function mutants

ABSTRACT: Plants with genotypes wild type, FIE loss-of-function and MIA loss-of-function were compared. Plants were grown in growth chambers at 70% humidity and daily cycles of 16 h light and 8 h darkness at 21 C. Plant material used for the experiments was pooled from 10 plants. Siliques without withering flower organs were harvested. The experiment was performed twice providing independent biological replicates.

The Polycomb-group (PcG) proteins MEDEA, FERTILIZATION INDEPENDENT ENDOSPERM, and FERTILIZATION INDEPENDENT SEED2 regulate seed development in Arabidopsis by controlling embryo and endosperm proliferation. All three of these FIS-class proteins are likely subunits of a multiprotein PcG complex, which epigenetically regulates downstream target genes that were previously unknown. Here we show that the MADS-box gene PHERES1 (PHE1) is commonly deregulated in the fis-class mutants. PHE1 belongs to the  ...[more]
