Washington, DC—The American Society of Plant Biologists (ASPB) will name a mentorship award in honor of legendary Carnegie plant scientist Winslow Briggs, who died in February. 

The ASPB is a professional society dedicated to the advancement of plant sciences.  Briggs served as its president in 1975.  He also received the society’s Stephen Hales Prize for noteworthy contributions to the field in 1994 and its Adolph E. Gude, Jr. Award for his service to the plant science community in 2007.

Briggs joined Carnegie as the Director of the Department of Plant Biology in 1973 after teaching both at Harvard University—where he completed his bachelor

Palo Alto, CA—Do plant scientists hold the key to saving vulnerable populations in a changing climate? How should plant researchers prepare to deploy their knowledge to maintain food security in the future—as well as to promote renewable energy, sequester carbon pollution from the atmosphere, and even synthesize medicine?

Between 2030 and 2050, climate change will cause about a quarter of a million deaths each year through malnutrition, infectious disease, and extreme heat, according to a 2018 World Health Organization report. Economic losses related to climate change are projected to be several hundred billion dollars a year in the U.S. alone by 2090. And we are

Palo Alto, CA—What factors govern algae’s success as “tenants” of their coral hosts both under optimal conditions and when oceanic temperatures rise? A Victoria University of Wellington-led team of experts that includes Carnegie’s Arthur Grossman investigates this question.

Corals are marine invertebrates that build large exoskeletons from which colorful reefs are constructed. But this reef-building is only possible because of a mutually beneficial relationship between the coral and various species of single-celled algae called dinoflagellates that live inside the cells of coral polyps.

These algae are photosynthetic, which means that like

Palo Alto, CA— Determining how one species becomes distinct from another has been a subject of fascination dating back to Charles Darwin. New research led by Carnegie’s Matthew Evans and published in Nature Communications elucidates the mechanism that keeps maize distinct from its ancient ancestor grass, teosinte.

Speciation requires isolation. Sometimes this isolation is facilitated by geography, such as mountains chains or islands that divide two populations and prevent them from interbreeding until they become different species. But in other instances, the barriers separating species are physiological factors that prevent them from successfully mating, or from

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

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.

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 produce cells called spores. Each spore divides forming a single set of chromosomes (haploid) --the gametophyte--which produces the sperm and egg cells.

Evans studies how the haploid genome is required for normal egg and sperm function. In flowering plants, the female gametophyte, called the embryo sac, consists of four cell types: the egg cell, the central cell, and two types of

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

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
