Other claims from this paper (7)
- Intervention effect Toxin expression blocked sperm development before final division and left one sperm-like cell per pollen tube.
- Observation Single-cell pollen tubes targeted ovules and fertilized either egg or central cell.
- Observation Fertilization yielded seeds with either endosperm or embryo, but not both.
- Mechanism Authors infer preferential central-cell fusion by single sperm-like cells.
- Mechanism Authors infer that de novo translation is required to complete sperm development.
- Observation Authors infer tight control of the HAP2(GCS1) promoter.
- Mechanism Disrupted gene expression can bias male germ-cell gamete fusion.
