New research from Washington University in St. Louis offers clues about how mechanosensitive ion channels in the plant’s cells respond to swelling by inducing cell death — potentially to protect the rest of the plant.
The Dixit lab at Washington University in St. Louis, which in a study published in 2018 found molecular brakemen that keep the Arabidopsis Fragile Fiber 1 (FRA1) motor protein in check, uncovered in continuing research that FRA1 cinches its track in place through cellulose synthase-microtubule uncoupling proteins.
Three Washington University in St. Louis scientists studied the great granddaddy of all photosynthetic organisms — a strain of cyanobacteria — to develop the first experimental map of that organism’s water world.
Mike Dyer, supervisor of the greenhouse on the campus of Washington University in St. Louis, has the job many of us probably wish we had — but only because we think he spends the day pottering around watering plants. Instead, his job requires everything from the mechanical and engineering skills needed to suppress the greenhouse’s voracious appetite for energy; extensive knowledge of insects; and the ability to grow any plant he is handed under the conditions specified. It’s not exactly relaxing, but he enjoys it that way.
Chancellor Mark S. Wrighton has announced the creation of new four-year fellowships in the Division of Biology and Biomedical Sciences, made possible by a generous gift from William H. Danforth. Danforth hopes the new fellowships will attract highly motivated students to this field of study and foster a culture of intellectual entrepreneurship focused on research and innovation in plant sciences.
