How do plants respond to environmental cues?

• Gravity sensing: How does a plant convert an acceleration force into cellular information?
• Auxin Transport: How is the distribution of this hormone targeted to individual cells?
• Gravity signaling: What is the chain of events that leads to gravitropic curvature?
• Phototropism: How does a light gradient cause differential growth?
• Photomorphogenesis: What is light-induced development, and how is it regulated?
• Touch Sensing: How does a plant detect an object and grow around it?
