Pollen grain , due to its unique structural organization , an extremely convenient experimental model both cytological , molecular and genetic factors. Ease of their isolation , extraction of pollen and DNA, RNA and proteins had resulted in male gametophyte cells of angiosperms are currently among the most intensively studied plant structures . Extremely intense in recent years the development of research tools exploring the genome resulted in numerous works on various aspects of gene expression during microsporogenesis and microgametogenesis in angiosperms .

Dynamin and dynamin-related proteins (DRP) participate in many processes essential for normal function of the cells and organisms. They were found both in animals and plants. In Arabidopsis thaliana 16 different dynamin-related proteins were identified that are grouped into six subfamilies. DRP1 and soybean fragmoplastin participate in the cell plate formation during cytokinesis. Two mem- bers of DRP2 subfamily display domain structure similar to mammalian classical dynamins and may be involved in endocytosis and membrane recycling via clathrin-coated vesicles.

Polar auxin transport (PAT) is a process that controls all stages of plant growth and development . Knowing responsible for this process mechanisms thus became one of the main goals of modern science . With the latest research using molecular biology techniques were able to confirm wagered decades earlier hypothesis chemioosmotyczną . According to the PAT is achieved by the presence in the cytoplasmic membrane of specialized carriers entering (AUX) and leaving (PIN) from the cell auxin . Are currently known families of genes encoding said carriers .
