Plants by the Numbers: Math, Computation and the Future of Plant Biology

by Greg Watry

What does the future of plant biology education and research look like? That’s the question on the mind of Siobhan Brady, associate professor of plant biology at UC Davis.

In a Plant Physiology commentary paper, Brady, along with 37 other plant biologists from around the world, call for universities to integrate more quantitative and computational techniques into biology-oriented academic curricula. Introducing these skills early, the group advises, will help prepare tomorrow’s plant biologists for the next era of genomics research.

Podcast: Science at the Root

In this episode of our Three Minute Egghead podcast, UC Davis plant biologist Siobhan Brady talks about her work on roots.

Roots are the key innovation that allowed plants to conquer the land. They allow a plant to explore its environment, seeking out water and nutrients. A cell type within roots called xylem transports water and also provides support for land plants, allowing them to grow swiftly like a field of corn or reach towering heights of a sequoia.

Brady’s lab is looking at the network of genes that work together to control how xylem cells develop and grow, looking especially at the lab plant Arabidopsis, domestic tomato and its wild relatives, and the African staple crop sorghum.

Plant Genes May Lack Off Switch, But Have Volume Control

By Jenna Gallegos

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots instead.

Professor Alan Rose has been working for over two decades to unravel a mechanism called “intron-mediated enhancement.” I’m a graduate student in Rose’s lab, and we made an exceptional discovery in an unexceptional plant called Arabidopsis thaliana, or thale cress.
