Channels in plant cell walls, called plasmodesmata, provide molecules with a bridge to move between cells, an essential phenomenon for cellular growth and development. The mystery has long been how ...

Plant Cell Walls Can Control Growth in the Dark To maintain an energy-saving growth strategy in the absence of light, seedlings need signals generated by pectin in their cell walls.

Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant growth in conjunction with WOX5. Understanding this mechanism is relevant for ...

Using a computer model that reveals how plants grow thicker over time, biologists have uncovered how cells are activated to produce wood tissue. Understanding the genetic and molecular signals behind ...

Plant regeneration relies on a delicate balance between stem cell renewal and differentiation, yet the evolutionary origin and functional limits of key regulators remain poorly understood. This study ...

AMES, Iowa – Hongqing Guo studies a gene that affects both how plants grow and how they respond to environmental threats, hoping to unravel – and then harness – the balancing act between fortifying ...

A professor of plant molecular biology wants people to know that plants have stem cells too. Just like in the medical world, plant stem cells could support human growth and development when used to ...
