RESUMO
The levels and types of phospholipids changed in distinct phases during the germination of 32P-labeled uredospores of Uromyces phaseoli. During the first 20 minutes of germination, the phospholipid content dropped to 40% of the pregermination level. Between 2 and 3 hours, phospholipid levels increased to approximately 80% of the pregermination levels, and after germination for 5 hours, catabolism had reduced the 32P-lipids to about the same level observed prior to the first anabolic phase. A second anabolic phase was observed between 5 and 10 hours of germination. Phosphatidylcholine and phosphatidylethanolamine, the major phospholipids, did not undergo anabolism and catabolism at the same rates during germination. Only small quantities of the more polar phospholipids were released to the germination media.
