However, little is known about the molecular basis of this quantitative trait, in contrast with the many studies available on cell differentiation in the stamen. Recently, the first gene responsible for pollen number variation, <i>REDUCED POLLEN NUMBER1</i> (<i>RDP1</i>), was isolated by genome-wide association studies of <i>Arabidopsis thaliana</i> and exhibited the signature of natural selection. This gene encodes a homolog of yeast Mrt4 (mRNA turnover4), which is an assembly factor of the large ribosomal subunit. However, no further data were available to link ribosome function to pollen development. Here, we characterized the <i>RDP1</i> gene using the standard <i>A. thaliana</i> accession Col-0.
