Researchers identify molecular signaling system that is crucial for plant fertility
...abidopsis flowers produce high levels of GABA then eliminate varying amounts of it from different structures, so that a small amount is present at the surface of the pistil, where it stimulates pollen tube growth. Higher concentrations are found closer to the eggs, leading the tubes toward the target. The stu...Testing method may be culprit behind abnormal pap test results
