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 . This paper presents a synthesis of the currently available knowledge on the transcriptome and proteome of pollen during the differentiation of the male gametophyte , particularly in Arabidopsis thaliana . The vast majority of reports presented discusses the results of studies conducted using microarray , which was constructed using the learned sequence of the genome of Arabidopsis thaliana.
