Pollen tubes extend through pistil tissues and are guided to ovules where they release sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic medium, their trajectory is random and their growth rates are slower compared to growth in pistil tissues. Furthermore, inte...

Although two genes responsive to GABA were characterized previously in plants (Kathiresan et al 1997), a comprehensive study in reproductive and vegetative tissues has not been performed. Consequently, genes that mediate GABA response in plants remain unknown. We therefore used microarrays to survey...
