Arabidopsis HAP2 (GCS1) is a sperm-specific gene required for pollen tube guidance and fertilization.

Development (Cambridge, England) - 1 Dec 2006

von Besser Kiera, Frank Aubrey C, Johnson Mark A, Preuss Daphne

Abstract excerpt

In flowering plants, sperm cells develop in the pollen cytoplasm and are transported through floral tissues to an ovule by a pollen tube, a highly polarized cellular extension. After targeting an ovule, the pollen tube bursts, releasing two sperm that fertilize an egg and a central cell. Here, we...
