PICKLE acts during germination to repress expression of embryonic traits.

PICKLE (PKL) codes for a CHD3 chromatin remodeling factor that plays multiple roles in Arabidopsis growth and development. Previous analysis of the expression of genes that exhibit PKL-dependent regulation suggested that PKL acts during germination to repress expression of embryonic traits. In this study, we examined the expression of PKL protein to investigate when and where PKL acts to regulate development.
