Washington, DC—Pioneering microbiome specialist Margaret McFall-Ngai has been named the inaugural director of Carnegie’s newly launched research division focused on life and environmental sciences, which will deploy an integrated, molecular-to-global approach to tackling the challenges of sustainability, resilience, and adaptation to a changing climate. McFall-Ngai will join the institution in January, 2022, from the University of Hawai‘i at Mānoa, where she is a professor at the Pacific Biosciences Research Center’s Kewalo Marine Laboratory and the center’s director emerita.

Palo Alto, CA—New work led by Carnegie’s Kangmei Zhao and Sue Rhee reveals a new mechanism by which plants are able to rapidly activate defenses against bacterial infections. This understanding could inspire efforts to improve crop yields and combat global hunger.

“Understanding how plants respond to stressful environments is critical for developing strategies to protect important food and biofuel crops from a changing climate,” Rhee explained. 

Published in eLife, new work from Zhao and Rhee, along with Carnegie’s Benjamin Jin and Stanford University’s Deze Kong and Christina Smolke, investigated how production of a plant defense

Palo Alto, CA—Carnegie’s Devaki Bhaya is part of a Rice University led team that was recently awarded $2.8 million from the National Science Foundation for a five-year project to define the social order of naturally occurring microbial communities.

Unlike the bacterial clones used in laboratory research, naturally occurring bacterial populations are havens of small-scale genetic diversity, making their relationships and evolutionary dynamics of great interest to the scientific community.

“From extremophiles living in deep sea vents to the beneficial bacteria living in the human gut or in association with plant roots, microbial communities are crucial to

Palo Alto, CA—Former Carnegie Staff Associate Martin Jonikas, now an Associate Professor of Molecular Biology at Princeton University, was named one of 33 new Howard Hughes Medical Institute (HHMI) Investigators. HHMI recognized Jonikas for his research on photosynthetic algae, which could revolutionize agriculture and biofuels by making crop plants better at converting carbon dioxide from the atmosphere into usable energy sources such as sugars.

Each member of the cohort will receive roughly $9 million over a seven-year term. They were selected for “diving deep into tough questions that span the landscape of biology and medicine.”

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

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

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.

Zhiyong Wang was appointed acting director of Department of Plant Biology in 2018.

Wang’s research aims to understand how plant growth is controlled by environmental and endogenous signals. Being sessile, plants respond environmental changes by altering their growth behavior. As such, plants display high developmental plasticity and their growth is highly sensitive to environmental conditions. Plants have evolved many hormones that function as growth regulators, and growth is also responsive to the availability of nutrients and energy (photosynthates).

To understand how plant cells perceive and transduce various regulatory signals, and how combinations of complex
