Mary Williams

I studied Biochemistry at Berkeley (BA), Plant Molecular Biology at Rockefeller (PhD), did a postdoc at Berkeley with Ian Sussex, and then spent 14 years as a Biology professor at Harvey Mudd College in Claremont, California. In 2009 I started working at the American Society of Plant Biologists as Features Editor of the journal Plant Cell and the developer of Teaching Tools in Plant Biology. My passion lies in making it a little bit easier for students of all ages to understand plants and plant science research. I live in Glasgow, Scotland, with my family and our much adored dog.

Jurassic Park? No, Precambrian Rubisco

by

In a study reminiscent of Jurassic Park, scientists have resurrected an extinct enzyme and watched it respond to today’s world. Rubisco is much older than dinosaurs; it is an ancient enzyme, billions of years old, and predates the origin of eukaryotes. Rubisco is found in all photosynthetic organisms, be they bacteria, algae or plant, as … Read more

Putting Down Roots: How Nitrate and Abscisic Acid Help Shape Root System Architecture

by

This week’s Research in Focus is reprinted from an In Brief published by Science Editor Jennifer Lockhart in The Plant Cell, which summarizes an article newly published by Ondzighi-Assoume et al. This study examines how internal and external signals affect lateral root production, and specifically the interaction between nitrate and the hormone abscisic acid (ABA). … Read more

Plant Molecular Genetics video lecture series

by

Previously we shared a list of videos spanning the plant biology part of an introductory biology course at the University of California at Berkeley. A reader shared a link to another plant biology course taught at Berkeley, the Plant Molecular Genetics (PMB160) course, taught in 2012 by Jenn Fletcher and Bob Fischer.  Here is a … Read more
