Outline of Final Research Achievements |
Gravitropism is a plant's gravity response, which enables plants to orient their photosynthetic organs upward and to the sunlight. The mechanisms in the gravitropism have been studied extensively, and revealed to be regulated by polar transport of auxin. On the other hand, mechanical resistance is another gravity response distinct from gravitropism. Under hypergravity stimuli, plants increase the rigidity against the gravitational force. We reported that brassinosteroid determines stem rigidity and length of elongation zone that have capability to respond to gravistimulation. In this study, we revealed that brassinosteroid-dependent cell wall regulation is important for mechanical resistance of Arabidopsis inflorescence stems.
