Bridging the gap between amyloplasts and directional auxin transport in plant gravitropism.

abstract：:When plants encounter adverse environmental conditions, they often respond by modifying their growth patterns. This growth response tunes morphogenesis with environmental demands and allows plants to prioritize stress response over growth. The underlying molecular mechanism involves an active reprogramming of cell pro...
