 Title    On the DNA Content of the Bacteroids of Rhizobium japonicum  
 Abstract    The DNA content of bacteroids from large nodules of soybean plants infected with Rhizobium japonicum strain 61 -A -101 was found to be 1.20 x 10~14 g per cell. Bacteroids from smaller nodules had slightly less DNA as did the stationary phase, free-living cells; both giving a value of 0.92 x 10-14 g per cell. In comparing these data with those of other workers it was found that there is little evidence to support suggestions that bacteroids possess anything less than a full genetic complement of DNA and that some misinterpretation of older published data has occurred.

 Title    DNA Content and Fragmentation of the Egg Nucleus of Trichoplax adhaerens  
 Abstract    Under culture conditions the egg nucleus o f Trichoplax adhaerens reaches an unusually high and variable DNA content. Before the "fertilization membrane" is formed, the nucleus undergoes fragmentation. It is assumed that culture conditions differ from natural conditions by preventing the switch-over from the S-phase to the G 2-phase o f the cell cycle: DNA replication continues and nuclear division is impossible. Cleavage ceases at an earlier or later stage.
