Abstract

An investigation of the distribution of deoxyribonucleic acid in the female gametophyte of the angiosperm Myosurus has revealed that the egg and polar nuclei show no detectable Feulgen reaction. Deoxyribonucleic acid was nevertheless demonstrated in these nuclei by means of fluorescence microscopy and ultraviolet microspectrography.These latter techniques also showed the presence of appreciable quantities of deoxyribonucleic acid in the cytoplasm of the two-nucleate embryosac and of the egg.The significance of these results is discussed in relation to the existing knowledge of the distribution of deoxyribonucleic acid in the eggs of plants and animals.
