Abstract:
Microsporogenesis is essential for male fertility and requires both the formation of somatic and reproductive cells in the anther and meiotic segregation of homologous chromosomes. Molecular genetic studies have uncovered signaling molecules and transcription factors that play crucial roles in determining the anther cell types and in controlling gene expression for microsporogenesis. At the same time, key components of in meiotic recombination pathways have been discovered, enriching our knowledge about plant reproductive development.
