Abstract Background During flowering central anther cells switch from mitosis to meiosis ultimately forming pollen containing haploid sperm. Four rings of surrounding somatic cells differentiate to support first meiosis and later pollen dispersal. Synchronous development of many anthers per tassel and within each anther facilitates dissection of carefully staged maize anthers for transcriptome profiling. Results Global gene expression profiles of 7 stages representing 29 days of anther development are analyzed using a 44 K oligonucleotide array querying approximately 80 of maize proteincoding genes. Mature haploid pollen containing just two cell types expresses 10 000 transcripts. Anthers contain 5 major cell types and express 24 000 transcript types each anther stage expresses approximately 10 000 constitutive and approximately 10 000 or more transcripts restricted to one or a few stages. The lowest complexity is present during meiosis. Large suites of stage-specific and co-expressed genes are identified .
