How Plant Cells Build The Wall

By Ann Filmer

Animations and models of plant cell division are part of a new project investigating how plant cells form their distinctive walls.

Cell division is a fundamental aspect of life. Without cell division, living organisms do not grow. The last step of cell division, also called cytokinesis, is uniquely different in plants from that in animals and fungi due to the presence of cell walls in plants.

This 4D time sequence imaging from Georgia Drakakaki’s lab at UC Davis shows how new plant cell walls form between divided plant cells. Green, vesicles forming cell wall and red, cell membranes.

Seeing Plants in Three Dimensions

Scientists are taking a new look at the inner workings of plants by imaging and modeling them in three dimensions.

“We’ve realized tremendous advances in technology for 3-D imaging of leaves,” said Tom Buckley, assistant professor of plant sciences at UC Davis.

Recent developments are summarized in an article in Trends in Plant Sciences, which sprang from a 2017 workshop at the University of Sydney organized by Buckley and Professor Margaret Barbour, University of Sydney.
