Carnegie's Arthur Grossman is spearheading the organization of the conference, sponsored by Carnegie's Department of Plant Biology, which will be held at Carnegie Science's Headquarters in our nation's capitol. The program will have an international attendance, a strong interdisciplinary orientation, will touch on many areas of biology and foster extensive collaborations among researchers in the field. Chlamydomonas reinhardtii has become a...
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...
A Celebration of 66 Years of Photobiology Research: Winslow Briggs has been conducting and publishing research for 66 years, right up to the present day (he is presently growing and measuring fava bean plants in the greenhouse). His incomparable career has been highlighted by many seminal discoveries. These include the demonstration that light regulates auxin transport in phototropism (the bending of plants toward light), the discovery 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-...
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...
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...
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...
The Dinneny lab at the Department of Plant Biology, Carnegie Institution for Science is mobilizing a fundraiser for the victims of the 7.1 magnitude earthquake that hit Mexico on Sept 19, 2017. Donations can be made through the following youcaring link. Here are some words from Dinneny lab's Cesar Cuevas-Velazquez: On Tuesday, Sept.19, 2017, a 7.1 magnitude earthquake hit the state of Morelos in Mexico, strongly impacting several...
Palo Alto, CA— The red algae called Porphyra and its ancestors have thrived for millions of years in the harsh habitat of the intertidal zone—exposed to fluctuating temperatures, high UV radiation, severe salt stress, and desiccation. Red algae comprise some of the oldest non-bacterial photosynthetic organisms on Earth, and one of the most-ancient of all multicellular lineages. They are also fundamentally integrated into human culture...
