Sažetak
Initial biomineralization in the early embryos of the sea slug Aplysia californica Cooper, 1863, was examined by X-ray diffraction (XRD) and ICP AES elemental analysis. XRD results showed that the first aragonite crystals were formed in the five days old embryos. The crystallite size of aragonite and its fraction in the total body mass increased during further developmental stages – until the first coil of the veliger shell was formed. The elemental ICP AES analysis confirmed XRD results, providing a more detailed explanation of different elements that influenced the first biomineral formation. By combining results obtained by the above mentioned instrumental methods with results of some physiological processes during the embryo development (e.g. enzymatic activity of carbonic anhydrase, proteomics), we are able to describe the most important mechanisms and processes of biomineralization in this “model organism”. Furthermore, these results can help in a better understanding and explanation of some, up to now, unanswered questions related to general ecological, environmental and also evolutionary aspects of biomineralization not only in Aplysia species but generally in all molluscs.
