Analysis of Transcriptome of Rice Anther

摘要

Important phenomena related to rice, such as Cytoplasmic male sterility (CMS), self-incompatibility and sex determination, are involved in sexual reproduction. For rice, the development process of male gametophyte and pollen contains several stages, including pre-meiotic anther (PMA), meiosis (MEI), tetrad (TET), uninuclear (UN) microspore, bicellular (BC) pollen, tricellular (TC) pollen, MEI,TET, and UN tapetum. With the 44K rice microarray chip and RNAs derived from LM-separated microspore/pollen and tapetum cells, in this paper, we identified the expression pattems involved in different stages. Furthermore, we also detected the enriched promoter motifs and enriched functions for each cluster, which are expected to provide biological insights into developmental procedure of male gametophyte and pollen.
