8.4 Gravitropism On Earth, the direction of the gravitational acceleration vector can indicate the location of water/nutrients ( ...

For other plants, such as white clover (Trifolium repens) and lentil (Lens culinaris) roots, amyloplasts were grouped near the c ...

plants which develop in microgravity are still responsive to gravitational acceleration, suggesting that components of gravity p ...

Studies with downstream elements in the signal-transduction cascade of tropisms in microgravity may provide significant contribu ...

What is the minimum gravitational acceleration that can be detected in plants to in- duce a response (g-threshold)? How do the ...

elicit a curvature response (Perbal and Driss-Ecole 2002). Future studies in microgravity can clarify the nature of the duration ...

The sensitivity of plants to light is difficult to study on Earth due to the interacting ef- fects from gravity. Therefore, micr ...

Crew involvement in experiments allows for more complex experimental design and analyses. For example, two tropism experiments, ...
