Transcription profiling by array of Arabidopsis seedlings mutant for essp3 and brm

ABSTRACT: Synthesis and accumulation of seed storage proteins (SSPs) is an important aspect of the seed maturation program. Genes encoding SSPs are specifically and highly expressed in the seed during maturation. However, the mechanisms that repress the expression of these genes in leaf tissue are not well understood. To gain insight into the repression mechanisms, we have performed a transgenic screening for mutants that express SSPs in leaves. Here we show that mutations of BRAHMA (BRM), a SNF2 chromatin remodelling ATPase, cause the ectopic expression of a subset of SSPs and other embryogenesis related genes in leaf tissue. Consistent with the notion that such SNF2-like ATPases form protein complexes in vivo, we observed similar phenotypes for mutations of AtSWI3C, a BRM interacting partner, and
