PSK2 — Asparagus officinalis
Summary
A4U43_C03F7880, designated PSK2 (AoPSK2) on asparagus chromosome 3, encodes a phytosulfokine family protein with growth factor activity. The gene is associated with sulfation, cell population proliferation, digestion, plant organ morphogenesis, cellular response to hypoxia, and cell differentiation. Its product localises to the extracellular matrix, Golgi complex, and extracellular space. PSK2 has been linked to primary root growth, cell proliferation, plant growth, fungal defense, wound response, and pollen tube growth. Related genes in other species link the family to male fertility and cell growth, and to traits including plant male sterility, cell growth and development, pollen fertility restoration, root morphology, and reduced primary root length.
