[Cytochemical study of the DNA and histone in the tissues of the lily anther in the course of microsporo- and gametogenesis].
The DNA and histone content in the microsporocytes, microspores, generative and vegetative cells of the pollen grain of Lilium candidum L., as well as in the anther wall tissues, was estimated by double wavelength cytophotometry. The lack of histone, as compared with DNA content, was demonstrated in the microsporocytes at the late premeiotic interphase and early meiotic prophase, as well as in the young microspores and anther wall tissues. The analysis of hydrolysis curves suggests the increase of non-condensed chromatin during endothelial cell differentiation.
