BESC Imaging of Plant Cell Walls at Multiple Scales.
BESC researchers are integrating technologies for imaging plant tissues and cell walls from millimeter to nanometer scales. Shown is part of a cross-section of a switchgrass stem at micrometer scale. Autofluorescent signals from compounds in the stem show less lignin and more sunlight-absorbing chlorophyll in the green outer layer on the right. Deeper blue areas toward the stem's center show more highly lignified xylem tissue used for water and nutrient transport.
