Summary We have been able to follow the increase in nuclear histones along the division cycle, using a natural synchronous meristematic cell population labelled by caffeine as binucleate. We have thus found a parallel increase in DNA and histone along the S period. Some increase in nuclear histones during the G1 and G2 has also been detected. At the same time a high rise of stainable histone in the nuclei in prophase has been found. Changes in the composition of nuclear histones have been followed counting the percentage of arginine-rich histones in the total histone content. Two peaks located at the beginning and at the end of the S period as well as a sharp descent of the percentage of arginine-rich histone in the prophasic nucleus have been found.
