Palo Alto, CA—Carnegie’s Devaki Bhaya has been named a Fellow of the California Academy of Sciences. She is one of 14 new members selected as “partners and collaborators in the pursuit of the Academy mission to explore, explain, and sustain life.”

At Carnegie’s Department of Plant Biology Bhaya studies how photosynthetic microorganisms are affected by environmental stressors such as light, low nutrient availability, and viruses. Her research on speciation in the microbial mats of Yellowstone National Park is providing insights into how microbial populations communicate, evolve, and share resources. These findings offered a first glimpse into the astonishing complexity and

Palo Alto, CA—Senior scientist Arthur Grossman of Carnegie’s Department of Plant Biology was part of a team* awarded a three-year grant, with $100,000 for each year, from the International Human Frontier Science Program (HFSP) Organization. The team will use an integrated approach to investigate how light and metabolic signals control photosynthetic processes in algae.  

HFSP’s collaborative research grants are given for endeavors that address “complex mechanisms of living organisms.” The program only supports “cutting-edge, risky projects” conducted by globally distributed teams.

Stanford, CA—Roots face many challenges in the soil in order to supply the plant with the necessary water and nutrients.  New work from Carnegie and Stanford University’s José Dinneny shows that one of these challenges, salinity, can cause root cells to explode if the risk is not properly sensed. The findings, published by Current Biology, could help scientists improve agricultural productivity in saline soils, which occur across the globe and reduce crop yields.

Salts build up in soils from natural causes, such as sea spray, or can be introduced as a consequence of irrigation and poor land management. Salinity has deleterious effects on plant health and limits crop yields,

Washington, DC— Without eyes, ears, or a central nervous system, plants can perceive the direction of environmental cues and respond to ensure their survival.

For example, roots need to extend through the maze of nooks and crannies in the soil toward sources of water and nutrients. The various ways that plants guide this branching to take advantage of their environment is of great interest to scientists and of potential use by farmers in need of crops that produce more food with fewer resources.

Carnegie and Stanford University biologist José Dinneny has spent years studying how root growth responds to water, particularly through a phenomenon called hydropatterning, which

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 to genes for which no function had

Fresh water constitutes less than 1% of the surface water on earth, yet the importance of this simple molecule to all life forms is immeasurable. Water represents the most vital reagent for chemical reactions occurring in a cell. In plants, water provides the structural support necessary for plant growth. It acts as the carrier for nutrients absorbed from the soil and transported to the shoot. It also provides the chemical components necessary to generate sugar and biomass from light and carbon dioxide during photosynthesis. While the importance of water to plants is clear, an understanding as to how plants perceive water is limited. Most studies have focused on environmental conditions

Carnegie researchers recently constructed genetically encoded FRET sensors for a variety of important molecules such as glucose and glutamate. The centerpiece of these sensors is a recognition element derived from the superfamily of bacterial binding protiens called periplasmic binding protein (PBPs), proteins that are primary receptors for moving chemicals  for hundreds of different small molecules. PBPs are ideally suited for sensor construction. The scientists fusie individual PBPs with a pair of variants and produced a large set of sensors, e.g. for sugars like maltose, ribose and glucose or for the neurotransmitter glutamate. These sensors have been adopted for measurement of sugar

One way to adapt to climate change is to understand how plants can thrive in the changing environment. José Dinneny looks at the mechanisms that control environmental responses in plants, including responses to salty soils and different moisture conditions—work that provides the foundation for developing crops for the changing climate.

The Dinneny  lab focuses on understanding how developmental processes such as cell-type specification regulate responses to environmental change. Most studies have considered the organ or even the whole organism as a single responsive unit and ignore the potential diversity of responses by the various cell-types composing an organism. Dinneny has

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 supporting

It’s common knowledge that light is essential for plants to perform photosynthesis—converting light energy into chemical energy by transforming carbon dioxide and water into sugars for fuel. Plants maximize the process by bending toward the light in a process called phototropism, which is particularly important for germinated seedlings to maximize light capture for growth. Winslow Briggs has been a worldwide leader in unraveling the molecular mechanisms behind this essential plant process.

Over a decade ago Briggs and colleagues discovered and first characterized the photoreceptor family that mediates this directional response and named the two members phototropin 1 and

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
