Imaging Cell Wall Architecture in Single Zinnia elegans Tracheary Elements

The chemical and structural organization of the plant cell wall was examined in Zinnia elegans tracheary elements (TEs), which specialize by developing prominent secondary wall thickenings underlying the primary wall during xylogenesis in vitro. Three imaging platforms were used in conjunction with chemical extraction of wall components to investigate the composition and structure of single Read More …

A Bold New Biology Beamline

“Life at the top is nice,” remarked Paul Alivisatos, as Berkeley Lab’s director kicked off the ceremonies to inaugurate beamline 5.4, the palindromic BSISB – Berkeley Synchrotron Infrared Structural Biology program – located on the roof blocks of the Advanced Light Source’s linac and beamline test facility. With a nod to Jim Krupnick, the Lab’s Read More …
