Functional dissection of a napin gene promoter: identification of promoter elements required for embryo and endosperm-specific transcription.

abstract：:Lysine residue 9 of histone H3 can either be acetylated or mono-, di-, or tri-methylated. These epigenetic states have a diverse impact on regulating gene transcriptional activity and chromatin organization. H3K9ac is invariably correlated with transcriptional activation, whereas H3K9me2 has been reported to be mainly...
