How Roots Develop | Fundamental Concepts

Why even study plants, much less roots? Professor Philip Benfey discusses root genetics and why plants are at the center of some of the major problems facing the world today.
This video is part of Duke University's Fundamental Concepts series. Each episode features a Duke faculty member explaining an entire concept from beginning to end in roughly 10 minutes.

One of the key questions in developmental biology is how cells acquire their identities. This is an important question in human development where stem cells divide and differentiate into skin, muscle, fat, etc. It is equally central to plant development where most organs and cells are formed from stem cell populations known as meristems. The Benfey Lab addresses this question using a combination of genetics, molecular biology, and genomics to identify and characterize the genes that regulate formation of the root in the plant model system, Arabidopsis thaliana. The choice of the root as a model was based on the simplicity of its organization and its stereotyped developmental program 🔗 sites.duke.edu...

Plants are one of the most interesting subjects of biology in my opinion. One of my favorite plants is Bryophyllum pinnatum, because of the planlets that grow between the leaf margins.
