In her third talk, Braybrook switches gears and highlights work from her lab on cell walls found in brown algae (seaweed). Although seaweed cell walls have much in common with plant cell walls, they do have some differences. Seaweed cell walls contain much less cellulose than plants, in fact, most of the wall is made of the gel matrix material, alginate. Braybrook’s lab studies the Fucus seaweed embryo to learn how changes in the rigidity or fluidity of the gel matrix impacts cell expansion patterns during development.

The Cell Wall
Cell walls are found across the tree of life: in plants, seaweed, bacteria and even some animals! Learn how the unique chemical and physical properties of cell walls allow plants and seaweed to attain great heights and form amazing shapes. (Talk recorded in September 2019)
