Abstract
Meiotic cells of Lilium contain a protein that can be identified by its very high affinity for single-stranded DNA. The protein has not been found in either proliferating or nonproliferating somatic tissues. It is present only during the prophase stages in meiotic cells. This protein is localized in nuclei and has been isolated in association with lipid. Its properties are similar to those of “gene 32-protein” of T4 phage. It thus has the property of catalyzing the renaturation of DNA, and in its presence 60% of denatured lily DNA is converted to a double-stranded form at 25°C in 2 hr. The significance of this protein to meiotic recombination is considered in relation to other biochemical properties of meiotic cells.
