<P>Summary</P><P>CREB-binding protein (CBP) and its homolog p300 possess histone acetyltransferase activity and function as key transcriptional co-activators in the regulation of gene expression that controls differentiation and development in animals. However, the role of <I>CBP</I>/<I>p300-like</I> genes in plants has not yet been elucidated. Here, we show that Arabidopsis <I>CBP</I>/<I>p300-like</I> genes promote flowering by affecting the expression of a major floral repressor <I>FLOWERING LOCUS C</I> (<I>FLC</I>). Although animal CBP and p300 generally function as co-activators, Arabidopsis CBP/p300-like proteins are required for the negative regulation of <I>FLC</I>. This CBP/p300-mediated <I>FLC</I> repression may involve reversible protein acetylation independent of histone modification within <I>FLC</I> chromatin.</P>
