This thesis deals with the chemical communication of wood mouse of genus Apodemus with a focus on the special sebaceous gland on the ventral side of the tail - the caudal organ. Role of the caudal organ in chemical communication is unclear. To illustrate the function of the sebaceous glands, I decided to use metods of 454 pyrosequencing, proteomic analysis and qPCR. I created a database of transcriptionally active genes of caudal organ using 454 pyrosequencing. In proteomic analysis, I focused on proteins with a molecular weight 14-18kDa to verify the presence of the lipocalins, proteins involved in chemical communication. I compared the relative mRNA abundance of selected genes between individuals of the opposite sex using qPCR. In my research, I found that the caudal organ is active organ and caudal organ could participate in chemical communication. I detected a different relative mRNA abundance of genes in males and females at the mRNA level, which could play a role in differences in development of caudal organ between individuals of the opposite sex. Finally, I suggested possible ways of using the caudal organ in the chemical communication in wood mouse genus Apodemus from the obtained results. Key words: caudal organ, Apodemus, chemical communication, FABP5, Scd1
