New gene discovery revolutionizes male sterility in onions!
The wi gene in Allium choenoprasum causes male sterility, but it's not due to the cytoplasm type. It's actually a genic male sterility, not cytoplasmic. The sterility is stable and not affected by high temperatures or tetracycline. This means you can't temporarily induce pollen production to maintain sterile lines. This genic male sterility doesn't offer any advantages over the cytoplasmic male sterility system for hybrid breeding.
