Palo Alto, CA—Climate change and habitat destruction may have already caused the loss of more than one-tenth of the world’s terrestrial genetic diversity, according to new research led by Carnegie’s Moises Exposito-Alonso and published in Science. This means that it may already be too late to meet the United Nations’ proposed target, announced last year, of protecting 90 percent of genetic diversity for every species by 2030, and that we have to act fast to prevent further losses.

Several hundred species of animals and plants have gone extinct in the industrialized age and human activity has impacted or shrunk half of Earth’s ecosystems, affecting

Palo Alto, CA— Water is inextricably linked to our understanding of life—it makes up most of our planet’s surface and organisms across the tree of life depend on it to function. Yet the ability to survive extremely dry conditions for long periods is crucial to the life cycles of many species—including in plants, which can reproduce from desiccated pollen grains and grow from dried-out seeds.

“There are some desert plants and micro-animals, like tardigrades, which can lose up to 90 percent of their water and resume normal biological function within hours of being rehydrated. We want to know how they do it,” said Carnegie’s Sue Rhee, who was

Washington, DC— Aquatic ecologist Stephanie Hampton joined Carnegie as Deputy Director of Carnegie’s newly launched Division of Biosphere Sciences and Engineering at the end of July. She arrived from the National Science Foundation, where she was the director of the Division of Environmental Biology. She was also a professor and the former director of an interdisciplinary environmental research center at Washington State University.

“Stephanie’s experience leading the primary funder of basic ecological and evolutionary research in the U.S. has given her a 10-thousand-foot view of the field, which will help us as we implement a new, cross-disciplinary vision

Palo Alto, CA— New work led by Carnegie’s Zhiyong Wang untangles a complex cellular signaling process that’s underpins plants’ ability to balance expending energy on growth and defending themselves from pathogens. These findings, published in Nature Plants, show how plants use complex cellular circuits to process information and respond to threats and environmental conditions.  

“Plants don’t have brains like us, and they may be fixed in place and unable to flee from predators or pathogens, but don’t feel sorry for them, because they’ve evolved an incredible network of information-processing circuits that enable them to ‘

Revolutionary progress in understanding plant biology is being driven through advances in DNA sequencing technology. Carnegie plant scientists have played a key role in the sequencing and genome annotation efforts of the model plant Arabidopsis thaliana and the soil alga Chlamydomonas reinhardtii. Now that many genomes from algae to mosses and trees are publicly available, this information can be mined using bioinformatics to build models to understand gene function and ultimately for designing plants for a wide spectrum of applications.

 Carnegie researchers have pioneered a genome-wide gene association network Aranet that can assign functions

Plants are not as static as you think. David Ehrhardt combines confocal microscopy with novel visualization methods to see the three-dimensional movement  within live plant cells to reveal the other-worldly cell choreography that makes up plant tissues. These methods allow his group to explore cell-signaling and cell-organizational events as they unfold.

These methods allow his lab to investigate plant cell development and structure and molecular genetics to understand the organization and dynamic behaviors of molecules and organelles. The group tackles how cells generate asymmetries and specific shapes. A current focus is how the cortical microtubule cytoskeleton— an

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 what its genes do and how or why they do it. And understanding this evolution can help develop new crop strains to adapt to climate change.  

Sue Rhee wants to uncover the molecular mechanisms underlying adaptive traits in plants to understand how these traits evolved. A bottleneck has been the limited understanding of the functions of most plant genes. Rhee’s group is

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 and the impact of temperature and light on the bleaching process.

He also has extensively studied the blue-green algae Chlamydomonas genome and is establishing methods for examining the set of RNA molecules and the function of proteins involved in their photosynthesis and acclimation. He also studies the regulation of sulfur metabolism in green algae and plants.

Evolutionary geneticist Moises Exposito-Alonso joined the Department of Plant Biology as a staff associate in September 2019. He investigates whether and how plants will evolve to keep pace with climate change by conducting large-scale ecological and genome sequencing experiments. He also develops computational methods to derive fundamental principles of evolution, such as how fast natural populations acquire new mutations and how past climates shaped continental-scale biodiversity patterns. His goal is to use these first principles and computational approaches to forecast evolutionary outcomes of populations under climate change to anticipate potential future
