Abstract Background Pollen the male partner in the reproduction of flowering plants comprises either two or three cells at maturity. The current knowledge of the pollen transcriptome is limited to the model plant systems Arabidopsis thaliana and Oryza sativa which have tri-cellular pollen grains at maturity. Comparative studies on pollen of other genera particularly crop plants are needed to understand the pollen gene networks that are subject to functional and evolutionary conservation. In this study we used the Affymetrix Soybean GeneChip to perform transcriptional profiling on mature bi-cellular soybean pollen. Results Compared to the sporophyte transcriptome the soybean pollen transcriptome revealed a restricted and
