Center for Lignocellulose Structure and Formation

Our Mission

CLSF (Center for Lignocellulose Structure and Formation) is a DOE Energy Frontiers Research Center focused on developing a detailed understanding of lignocellulose, the main structural material in plants, from cellulose synthesis and fibril formation to a mature plant cell wall, forming a foundation for significant advancement in sustainable energy and materials.

  • Two researchers working in the CLSF lab.

    The central laboratory facility of CLFS at the University Park campus of Penn State houses specialty instruments including an atomic force microscope (AFM), which allows researchers to visualize plant cell wall architecture in the nano scale, and chromatography and spectroscopy systems to analyze proteins and sugars. Pictured are Tian Zhang (L) and Laura Ullrich.

  • molecular model illustration

    Putative molecular model of a single CESA associated with the plasma membrane. CESA has not yet been crystalized, but new ab initio computational protein folding reveals the approximate 3D CESA structure, which in turn clarifies how it functions.

  • Lei Lei looking through a microscope.

    Lei Lei and other members of the Ying Gu lab work to obtain spatial information about the cellulose synthase complexes through live imaging of plant cells with the aid of spinning disk confocal microscopy.

  • Two CLSF researchers working in the lab.

    The central laboratory facility of CLSF is utilized by many researchers; here our members can analyze plant cell wall components, observe protein-protein interactions and separate carbohydrate substances by using specialty instruments. These instruments include an Infrared and Raman spectrometer, an isothermal microcalorimeter, and an ion-exchange chromatography system, to name a few. Pictured are Liza Wilson (L) and Sarah Kiemle.

  • Two CLSF researchers working in the lab.

    Researchers in the Haigler Lab are performing cryo-fracture deep-etch transmission electron microscopy in combination with immunolabeling of particular protein constituents to explore further the composition and function of the cellulose synthesizing complex.
