The two projects at WSU were among 54 grants awarded for plant research, totaling more than $17 million, announced May 25 by the National Institute of Food and Agriculture’s (NIFA) Agriculture and Food Research Initiative program.
The Institute of Biological Chemistry (IBC) was established at Washington State University in 1980 to pursue fundamental research in the molecular biology and biochemistry of plants. Work at the IBC focuses on basic plant science with an emphasis on plant derived products synthesis, determinants of plant architecture, bioenergetics, and plant-microbe interacts. The research outcomes have potential applications in agricultural biotechnology, bioenergy, and medicine.

IBC News and Updates
Andrei Smertenko is leading the way on the science of long division; long division in trees, that is. The Washington State University molecular biologist studies the cellular architecture of plants in the hopes of helping grow renewable resources faster.
For example, wood is made up of cells, called xylem, and they do something no other cells do: they divide vertically.
But that takes a lot longer than normal cell division. Helping with these divisions are tiny cellular machines called phragmoplasts. Only land plants and their evolutionary ancestor algae make phragmoplasts.
“Super-long divisions in trees take a long time. Once we understand how the phragmoplast functions, we will be able to engineer trees with faster cell divisions and faster growth,” said Smertenko, a professor in WSU’s Institute of Biological Chemistry. “Fast-growing trees would produce timber and other renewable materials more quickly.”
Dr. Smertenko recently received National Science Foundation (NSF) CAREER program funding for this research into phragmoplasts. The award is for nearly $1 million, spread over five years. (Full Article)
This is Dr. Peters’ second such honor in the last three months — late last fall he was named a Fellow in the American Association for the Advancement of Science for his contributions in chemistry.
The American Academy of Microbiology represents the American Society for Microbiology, the world’s oldest and largest life science organization. The mission of the Academy is to recognize scientists for outstanding contributions to microbiology and provide microbiological expertise in the service of science and the public. Dr. Peters’ work involves understanding energy use in living creatures at the microbial level. (Full Article)
Dr. Helmut Kirchhoff recently published a journal article on photosynthetic membranes in Nature Plants.
Dr. Kirchhoff—who wrote the article with a former IBC post-doctoral scholar, Sujith Puthiyaveetil, now assistant professor at Purdue, and Bart van Oort, faculty at Vrije Universiteit Amsterdam—explores molecular forces that control the structure of energy converting photosynthetic membranes. This research helps to understand how complex structured membranes self-organize and react to environmental dynamics that allows plants to thrive in an ever-changing nature.
Saturated fat and particularly trans fat in the US diet are serious health risks, responsible for more than 50,000 excess deaths each year. Dr. John Browse, Regents’ Professor, has been awarded a three-year research grant from USDA-NIFA to alter metabolism in oilseed crops to reduce the levels of saturated and trans fats. Describing the goal of the project, Dr. Browse says, “Our discoveries in the model plant, Arabidopsis, have provided the knowledge needed to improve the composition of processed food oils. Now, we will be able to find out just how far we can go towards eliminating these undesirable saturated and trans fats”.
Election as an AAAS Fellow is a distinction bestowed upon AAAS members by their peers, in recognition of scientifically or socially distinguished efforts to advance science and its applications. AAAS is the world’s largest general scientific society and publisher of the journal Science (www.sciencemag.org).
Dr. Peters’ work examines energy conservation at the molecular level and how life generates energy from food by shearing off electrons. (Full Article)
Most children have a phase where they dream of the far reaches of the universe and working for NASA. Dr. Norman Lewis participated in a NASA outreach project that enabled seventh grade students at McCaffrey Middle School to participate in a project to begin to reveal how biology changes away from Earth’s gravity (Full Article).
Professor John Peters delivered an invited lecture in the opening plenary session at Plant Biology 2017, held in Honolulu, Hawaii, June 2017, at the Hawaii Convention Center. Professor Peters talk was entitled, “Innovative Solutions for Increasing the Impact of Biological Nitrogen Fixation on Crop Plants”. The annual plant biology meeting is hosted by the American Society for Plant Biologist (ASPB) and has been held for over eight decades and currently attracts more than 1,300 scientists from 40 countries.
The Kirchhoff lab published a paper recently entitled Sublocalization of cytochrome b6f complexes in photosynthetic membranes in Trends in Plant Sciences that presents a structural model that explains the variation in cytochrome b6f sublocalization data. They have been able to show that small changes in the distance between adjacent membranes in stacked grana regions either allow or restrict access of cytochrome b6f complexes to grana. If the width of the gap falls below a certain threshold, then the steric hindrance prevents cytochrome b6f access to grana. Evidence is presented that the width of stromal gap is variable, demonstrating that the postulated mechanism can regulate the lateral distribution of the cytochrome b6f complexes.
Professor Mark Lange assumes the presidency of the Phytochemical Society of North America (PSNA) in August 2017. PSNA is a nonprofit scientific organization whose membership is open to anyone with an interest in phytochemistry and the role of plant substances in related fields. The PSNA’s mission is to encourage and stimulate research on the chemistry and biochemistry of plant constituents, their effects upon plant and animal physiology and pathology, and their industrial importance and utilization.
Eleven CAHNRS staff and faculty members, undergraduates and graduate students were presented with the Leadership and Engagement Award of Distinction (LEAD) from the President of Washington State University, April 18 at Pullman’s Compton Union Building.
Presented jointly by the WSU Center for Civic Engagement and the Office of Student Involvement, the President’s Award for Leadership and Engagement honors people who show exceptional service, involvement, mentoring, leadership and social change in the university and their community.
Two from CAHNRS received Faculty and Staff awards: Marwa Sanad, research associate in the Institute of Biological Chemistry (IBC), and Debbie Christel, assistant professor in the Department of Apparel, Merchandising, Design and Textiles (AMDT).
“Mathematicians like translating biological processes into numbers,” said Andrei Smertenko, assistant professor in Washington State University’s Institute of Biological Chemistry. “I’m a biologist, and I want to help grow stronger, better trees.”
Peters is the new director of the Institute of Biological Chemistry (IBC) at Washington State University and a renowned biochemist who wants to know how energy is produced at a fundamental level.
Huánglóngbìng, or HLB, is also called “citrus greening disease,” and it is destroying orange, grapefruit and lemon trees around the world. Scientists haven’t been able to grow and maintain cultures of the bacterium that causes the disease.
“The simple answers didn’t work and we need a way to fight this,” said biochemist David Gang, a fellow in WSU’s Institute of Biological Chemistry.
