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%...

Washington, DC—California Governor Gavin Newsom on Monday announced $20 million in his 2023 fiscal year budget to support Carnegie’s new research facility in Pasadena. The proposed budget allocation still must clear the California State Senate and Assembly, which will begin to hold hearings in the coming weeks. It must be adopted by June 15. 

The new 135,000-square-foot, state-of-the-art campus will bring the institution’s life and environmental scientists together in a single location adjacent to Caltech—making a decisive investment in the global fight against climate change. The facility will house more than 200 new hires and relocated staff, who

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

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

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

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

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

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
