Plants slow growth quickly by changing enzyme activity
Researchers found that plants can slow growth immediately when they face sudden stress. Enzymes already in plant cells are modified so leaves react fast, and later the plant makes longer-term changes to survive.

Outer root layer controls twisted root growth
A research team found that the outer cell layer of roots (the epidermis) can control whether roots grow twisted or straight. Lab measurements and computer models explain why this layer has more mechanical influence, with implications for crops.
How mangroves survive saltwater
Scientists studied mangrove trees to learn why some plants tolerate repeated saltwater flooding. They found small cells and thicker cell walls help mangroves stay strong in salty, waterlogged conditions and suggest this could help make crops more salt-tolerant.
