Abstract excerpt

The establishment of a specific pollen wall pattern is essential for pollen development in flowering plants. This process largely depends on the formation of a temporary wall surrounding microspores in tetrads, known as the primexine, which is primarily composed of Arabinogalactan proteins (AGPs) and polysaccharides. NEF1, a gene identified two decades ago in Arabidopsis thaliana, is required for primexine...
