Abstract
Gnetum gnemon, a nonflowering seed plant and member of the Gnetales, expresses a rudimentary pattern of double fertilization that results in the formation of two zygotes per pollen tube. The process of double fertilization in G. gnemon was examined with light and fluorescence microscopy, and the DNA content of various nuclei involved in sexual reproduction was quantified with 4[prime],6-diamidino-2-phenylindole microspectrofluorometry.Male and female gamete nuclei pass through the synthesis phase of the cell cycle and increase their DNA content from 1C to 2C before fertilization. Each of the two zygotes found in association with a pollen tube is diploid and cont...
