Plant Science Stories
Palo Alto, CA—Senior scientist Arthur Grossman of Carnegie’s Department of Plant Biology was part of a team* awarded a three-year grant, with $100,000 for each year, from the International Human...
Stanford, CA—Roots face many challenges in the soil in order to supply the plant with the necessary water and nutrients. New work from Carnegie and Stanford University’s José Dinneny shows that one...
Washington, DC— Without eyes, ears, or a central nervous system, plants can perceive the direction of environmental cues and respond to ensure their survival.
For example, roots need to extend...
Science News magazine has selected José Dinneny, of Carnegie’s Department of Plant Biology, as one of ten young scientists to watch in 2017. The researchers were selected because they are likely to...
Stanford, CA— Carnegie Plant Biology Acting Director Sue Rhee and staff scientist...
Stanford, CA— How do green algae grow so quickly? Two new collaborations offer insight into how these organisms siphon carbon dioxide from the air for use in photosynthesis, a key factor in their...
Palo Alto, CA— The red algae called Porphyra and its ancestors have thrived for millions of years in the harsh habitat of the intertidal zone—exposed to fluctuating temperatures, high UV radiation,...
Palo Alto, CA— Algae dominate the oceans that cover nearly three-quarters of our planet, and produce half of the oxygen that we breathe. And yet fewer than 10 percent of the algae have been formally...

Fresh water constitutes less than 1% of the surface water on earth, yet the importance of this simple molecule to all life forms is immeasurable. Water represents the most vital reagent for chemical reactions occurring in a cell. In plants, water provides the structural support necessary for plant...
Today, humanity is increasingly aware of the impact it has on the environment and the difficulties caused when the environment impacts our communities. Environmental change can be particularly harsh when the plants we use for food, fuel, feed and fiber are affected by this change. High salinity is...
Carnegie researchers recently constructed genetically encoded FRET sensors for a variety of important molecules such as glucose and glutamate. The centerpiece of these sensors is a recognition element derived from the superfamily of bacterial binding protiens called periplasmic binding protein (...
Arthur Grossman believes that the future of plant science depends on research that spans ecology, physiology, molecular biology and genomics. As such, work in his lab has been extremely diverse. He identifies new functions associated with photosynthetic processes, the mechanisms of coral bleaching...
Plants are essential to life on Earth and provide us with food, fuel, clothing, and shelter. Despite all this, we know very little about how they do what they do. Even for the best-studied species, such as Arabidopsis thaliana --a wild mustard studied in the lab--we know about less than 20% of...
Matthew Evans wants to provide new tools for plant scientists to engineer better seeds for human needs. He focuses on one of the two phases to their life cycle. In the first phase, the sporophyte is the diploid generation—that is with two similar sets of chromosomes--that undergoes meiosis to...

Valdivia, Chile, and Washington, D.C.—Cancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that...
Plants have a complex system of hormones that guide their growth and maximize their ability to take advantage of the environment. One mastermind hormone is called brassinosteroid. It can turn on or...
Washington, D.C. —Until now it has not been clear how salt, a scourge to agriculture, halts the growth of the plant-root system. A team of researchers, led by the Carnegie Institution’s José Dinneny...
