Crystalline inclusions composed of guanine and related purines were identified in different photosynthetic eukaryotes. They were shown to serve as long-term, high capacity stores of nitrogen, however, they may have also other functions, e.g., light manipulation.
By means of Raman microscopy, we will investigate their biosynthesis, direct uptake, and post-uptake fate. Furthermore, other possible roles of purine crystals will be studied, especially those connected with their optical properties.
