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.

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

Palo Alto, CA— Carnegie plant biologists Sue Rhee and David Ehrhardt will lead one of 25 teams awarded a total of $64 million this week by the U.S. Department of Energy to pursue genomic research of potential biofuel crops.

“This research will help us improve crops grown for bioenergy and bioproducts while at the same time deepening our knowledge of complex and interacting biological processes within specific environmental systems,” said the agency’s Under Secretary for Science Paul Dabbar.

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

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

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

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.

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

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
