For a plant seedling to grow upwards and out of the soil so it can begin to photosynthesize, it must grow more in length than in width. Growth that occurs in one direction more than in another is called anisotropic growth. How do cells do this? In plants such as Arabidopsis, almost all of the initial increase in plant length or height is due to anisotropic growth of cells rather than cell division. In her second talk, Braybrook explains how her lab is using this system to study the role of cell wall components in determining anisotropic growth.

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)
