title: GABA, a new player in the plant mating game.
abstract: Pollen tubes are guided through female tissues to deliver sperms to the embryo sac. A recent study reveals a GABA gradient along the pollen tube path, which, together with guidance defects in GABA-overaccumulating mutants, implies a role for GABA in regulating pollen tube growth and guidance.
