title: Loss of nuclear DNA in leaves of rye.
abstract: The nuclear DNA content of rye leaf cells was cytophotometrically determined. At the commencement of differentiation nuclei in rye leaves remain standing at G1 phase. With further differentiation a remarkable diminution of nuclear DNA content occurs in diploid cells. The largest number of cells showing a loss of nuclear DNA content were found in the top of the leaf. The age of the leaf and the extent of diminution in nuclear DNA content are correlated.
