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

Science News magazine has selected José Dinneny, of Carnegie’s Department of Plant Biology, as one of ten young scientists to watch in 2017. The researchers were selected because they are likely to make big discoveries. The investigators are spotlighted in the October 14 edition of Science News available online today at www.sciencenews.org/SN10.

Dinneny looks at the mechanisms plants use to sense water availability and survive stressful conditions such as drought and high salinity. He investigates developmental pathways and molecular genetic mechanisms involved in shaping the plant to suit the environment. His work has included the processes of water-stress responses in plants at

Stanford, CA— Carnegie Plant Biology Acting Director Sue Rhee and staff scientist José Dinneny and their labs are part of a research effort led by The Donald Danforth Plant Science Center, one of the world’s largest independent plant science institutes, which today announced a 5-year, $16 million grant from the U.S. Department of Energy.

Building on earlier research using the often-studied model grass called green foxtail (Setaria viridis), this project will identify new genes and pathways that contribute to photosynthesis and enhanced water-use efficiency. The team will then deploy these genes using tools from the emerging field of synthetic biology to accelerate development of

Stanford, CA— How do green algae grow so quickly?  Two new collaborations offer insight into how these organisms siphon carbon dioxide from the air for use in photosynthesis, a key factor in their ability to rapidly take over a swimming pool or pond. Understanding this process may someday help researchers improve the growth rate of agricultural crops such as wheat and rice.

In two studies published this week in the journal Cell, a Princeton-led team with collaborators from Carnegie and the Max Planck Institute of Biochemistry reported the first detailed inventory of the cellular compartment called the pyrenoid, which algae use to collect and concentrate carbon dioxide, making the

Carnegie will receive Phase II funding through Grand Challenges Explorations, an initiative created by the Bill & Melinda Gates Foundation that enables individuals worldwide to test bold ideas to address persistent health and development challenges. Department of Plant Biology Director Wolf Frommer,  with a team of researchers from the International Rice Research Institute, Kansas State University, and Iowa State University, will continue to pursue an innovative global health research project, titled “Transformative Strategy for Controlling Rice Blight.”

Rice bacterial blight is one of the major challenges to food security, and this project aims to achieve broad, durable

Today, humanity is increasingly aware of the impact it has on the environment and the difficulties caused when the environment impacts our communities. Environmental change can be particularly harsh when the plants we use for food, fuel, feed and fiber are affected by this change. High salinity is an agricultural contaminant of increasing significance. Not only does this limit the land available for use in agriculture, but in land that has been used for generations, the combination of irrigation and evaporation gradually leads to increasing soil salinity.

The Dinneny lab focuses on understanding how developmental processes such as cell-type specification regulate responses to

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

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

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 interior

Wolf Frommer believes that understanding the basic mechanisms of plant life can help us solve problems in agriculture, the environment and medicine, and  even provide understanding of human diseases. He and his colleagues develop fundamental tools and technologies that advance our understanding of glucose, sucrose, ammonium, amino acid, and nucleotide transport in plants.

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell’s outer membrane, which seals and protects all living cells, to the cell’s interior. These transported molecules include sugars, which can be used to fuel growth or to respond to chemical signals of

Understanding how plants grow can lead to improving crops.  Plant scientist Kathryn Barton, who joined Carnegie in 2001, investigates just that: what controls the plant’s body plan, from  the time it’s an embryo to its adult leaves. These processes include how plant parts form different orientations, from top to bottom, and different poles. She looks at regulation by small RNA’s, the function of small so-called Zipper proteins, and how hormone biosynthesis and response controls the plant’s growth.

Despite an enormous variety in leaf shape and arrangement, the basic body plan of plants is about the same: stems and leaves alternate in repeating units. The structure responsible for

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
