A team including Carnegie's Martin Jonikas developed a highly sophisticated tool that will transform the work of plant geneticists
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity.
More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.
A type of single-cell green algae called Chlamydomonas reinhardtii is a leading subject for photosynthesis research. Despite its importance in the research world, few tools are available for characterizing the functions of its genes.
A team including Carnegie’s Martin Jonikas developed a highly sophisticated tool that will transform the work of plant geneticists by making large-scale genetic characterization of Chlamydomonas mutants possible for the first time. Their work is published by The Plant Cell.
Their tool is a major step forward in the goal of identifying the genes that are necessary for photosynthesis, as well as other cellular functions such as the production of oily fats that are crucial for biofuel development. The use of similar tools for non-photosynthetic, single-celled organisms has revolutionized the understanding of cellular processes in bacteria and yeast, as well as animals.
“Our sequencing tool enables genotyping Chlamydomonas on an unprecedented scale, opening the door to comprehensive identification of genes required for photosynthesis,” Jonikas said.
This work was funded by the Carnegie Institution for Science, the U.S. Air Force Office of Scientific Research, the National Science Foundation, and the Deutsche Forschungsgemeinschaft research fellowship.
The Carnegie Institution for Science is a private, nonprofit organization headquartered in Washington, D.C., with six research departments throughout the U.S. Since its founding in 1902, the Carnegie Institution has been a pioneering force in basic scientific research. Carnegie scientists are leaders in plant biology, developmental biology, astronomy, materials science, global ecology, and Earth and planetary science.

Using ultracold atoms trapped in light crystals, scientists from the MPQ, LMU, and the Weizmann Institute observe a novel state of matter that never thermalizes.
What happens if one mixes cold and hot water? After some initial dynamics, one is left with lukewarm water—the system has thermalized to a new thermal...
Physicists from Regensburg and Marburg, Germany have succeeded in taking a slow-motion movie of speeding electrons in a solid driven by a strong light wave. In the process, they have unraveled a novel quantum phenomenon, which will be reported in the forthcoming edition of Nature.
The advent of ever faster electronics featuring clock rates up to the multiple-gigahertz range has revolutionized our day-to-day life. Researchers and...

Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.
By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...
