Palo Alto, CA— Carnegie’s Sue Rhee and Moises Exposito-Alonso are leading members of an initiative to identify genes related to stress tolerance in the mustard plant field pennycress. Theirs was one of seven biofuel research projects awarded a total of $68 million over five years by the Department of Energy. 

Climate change is one of the greatest challenges facing humankind and scientists from a wide variety of fields are applying their expertise to help understand and mitigate its effects. This includes plant scientists, whose work can help maintain food security in a warming climate, sequester carbon pollution from the atmosphere, and develop renewable energy

Palo Alto, CA— Carnegie evolutionary geneticist Moises Exposito-Alonso was awarded a Max Planck Society’s Otto Hahn Medal for early career excellence. The prize is endowed with 7,500 euros.

Since 1978, the society has recognized outstanding scientific achievements among its recent Ph.D. recipients with the goal of motivating particularly talented individuals to pursue academic research careers. The 2020 award was given to six scientists in the biological and medical fields; 10 in human sciences; and 10 in the chemistry, physics, and technology sector. The recipients are nominated by the directors of the Max Planck Institutes at which they conducted their doctoral

Palo Alto, CA— Carnegie’s Moises Exposito-Alonso was selected for the Heidelberg Academy of Science’s Karl Freudenberg Prize in recognition of outstanding early career achievements in the natural sciences. The prize comes with a personal 10,000 Euro award.

Representing the German state of Baden-Württemberg, the academy honors several professors under the age of 40 with endowed prizes each year, including six in 2020. All of the recipients will give public presentations of their work, with dates to be announced. An evolutionary geneticist, Exposito-Alonso received his doctorate in 2018 from the Max Planck Institute for Developmental Biology in Tübigen.

Washington, DC— Carnegie evolutionary geneticist Moises Exposito-Alonso was named a member of the 2020 class of Forbes’ 30 Under 30 Europe list in science and healthcare. 

He was recognized for his lab’s pioneering use of genomic techniques to understand how plant species will evolve and keep pace with a changing climate. 

Out of the thousands of nominees, the 30 finalists in each of the 10 categories comprise “the world’s most impactful community of young entrepreneurs and game-changers,” said the publication in announcing his selection.

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

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.

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

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
