Palo Alto, CA— Carnegie’s Moises Exposito-Alonso is one of four recipients of the American Society of Naturalists’ Jasper Loftus-Hills Young Investigator Award in recognition of “outstanding and promising work” by individuals who are within three years of completing their Ph.D or in their final year of graduate school.

Exposito-Alonso is an evolutionary geneticist who joined Carnegie last September as a staff associate, a prestigious position designed for early career scientists who are ready to independently deploy creative approaches to challenging research projects. 

His lab is pioneering the use of genomics to ask whether species will

Stanford, CA— Corals depend on their symbiotic relationships with the algae that they host. But how do they keep algal population growth in check? The answer to this fundamental question could help reefs survive in a changing climate.

New work published in Nature Communications by a team including Carnegie’s Tingting Xiang, Sophie Clowez, Rick Kim, and Arthur Grossman indicates how sea anemones, which are closely related to coral, control the size of the algal populations that reside within their tissue.  

Like corals, anemones host photosynthetic algae, which can convert the Sun’s energy into chemical energy. An alga shares some of the sugars

Palo Alto, CA— Plant genetic diversity in Central Europe could collapse due to temperature extremes and drought brought on by climate change, according to a new paper in Nature led by Moises Exposito-Alonso, who joins Carnegie next month from the Max Planck Institute for Developmental Biology and UC Berkeley. Because only a few individuals of a species are already adapted to extreme climate conditions, the overall species genetic diversity could be greatly diminished, according to the findings. 

A team of researchers from the Max Planck institute, University of Tübingen, Technical University of Madrid, and UC Berkeley analyzed variants of the mustard plant

Palo Alto, CA— Carnegie plant scientists Devaki Bhaya and Arthur Grossman received a nearly $2 million grant from the U.S. National Science Foundation and the U.K. Biotechnology and Biological Sciences Research Council to study photosynthetic microbes from Yellowstone National Park’s Octopus Spring.

Together with Seppe Kuehn of the University of Illinois at Urbana-Champaign and Alison Smith and Chris Howe from the University of Cambridge, Bhaya and Grossman plan to use samples from the field to reconstruct in the lab the highly organized communities of bacteria that carpet the hot springs in a mat-like structure.

They will deploy sophisticated techniques 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 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.

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

Devaki Bhaya wants to understand how environmental stressors, such as light, nutrients, and viral attacks are sensed by and affect photosynthetic microorganisms. She is also interested in understanding the mechanisms behind microorganism movements, and how individuals in groups communicate, evolve, share resources. To these ends, she focuses on one-celled, aquatic cyanobacteria, in the lab with model organisms and with organisms in naturally occurring communities.

 Phototaxis is the ability of organisms to move directionally in response to a light source.  Many cyanobacteria exhibit phototaxis, both towards and away from light. The ability to move into optimal light
