Palo Alto, CA—Carnegie’s Arthur Grossman and Stanford University’s Ellen Yeh were awarded a $900, 000 grant this spring from the university’s public-private partnership Strategic Energy Alliance to research the synthesis of biofuels from a species of green microalgae called Botryococcus braunii.

Scientists from a diversity of research areas, including plant and algal biologists, are all applying their expertise to mitigate the dire consequences of climate change. But many first-generation biofuels, which are produced from edible crops like corn, pose a threat to food security by competing for land and freshwater reserves. They also often rely on fertilizers

Palo Alto, CA—Dehydrated plant seeds can lay dormant for long periods—over 1,000 years in some species—before the availability of water can trigger germination. This protects the embryonic plant inside from a variety of environmental stresses until conditions are favorable for growth and survival. However, the mechanism by which the baby plant senses water and reactivates cellular activity has remained a mystery until now.

New work jointly led by Carnegie’s Yanniv Dorone and Sue Rhee and Stanford University’s Steven Boeynaems and Aaron Gitler discovered a protein that plays a critical “go, or no-go” role in this process—halting

Palo Alto, CA—Carnegie’s Megan Ruffley was awarded a prestigious Plant Genome Postdoctoral Research Fellowship in Biology from the National Science Foundation to study the genetics underpinning a plant’s ability to adapt to a changing climate.

Plants are fundamental to life as we know it. They make Earth’s atmosphere oxygen rich and form the basis of our food chain. They provide useful materials from fabric to lumber to medicines. Plants also remove carbon dioxide from the atmosphere, taking up and sequestering about a quarter of the emissions released by human activity. All of this means that it is crucial to understand how plant life will respond to a

Palo Alto, CA—New work from a Stanford University-led team of researchers including Carnegie’s Arthur Grossman and Tingting Xiang unravels a longstanding mystery about the relationship between form and function in the genetic material of a diverse group of algae called dinoflagellates.

Their findings, published in Nature Genetics, have implications for understanding genomic organizational principles of all organisms.

Dinoflagellates include more than 2,000 species of marine and freshwater plankton, many of which are photosynthetic, and some of which also ingest other organisms for food. They play a wide variety of roles in various ecosystems, including extreme

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

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

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
