Cytochemical study of dna and histone in the tissues of the lilium candidum anther during micro sporogenesis and gametogenesis



Cytochemical study of dna and histone in the tissues of the lilium candidum anther during micro sporogenesis and gametogenesis



Ontogenez 10(3): 276-284



The DNA and histone content in the microsporocytes, microspores, generative and vegetative cells of the pollen grain of L. candidum L., and 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 noncondensed chromatin during endothelial cell differentiation.
