Abstract

The steady-state levels of H3 and H4 mRNAs transcribed from three H3 and two H4 multigene subfamilies were studied during germination and in different organs of maize. During germination the five subfamilies are expressed in parallel to DNA synthesis, but a 5-fold difference in the quantity of mRNAs transcribed per gene copy was found from our subfamily to another. In adult plants H3 and H4 mRNA levels are highest in organs containing meristematic tissues but also high in non-proliferating tissues. No strict tissue specificity expression could be detected but some subfamilies show preferential expression in some tissues.
