Developing Glandular Trichomes of Basil

Formation of glandular trichomes on lower leaf surface of a young leaf of basil (Ocimum basilicum). The smaller trichomes with four evident cells have just formed and the cuticles covering their four glandular cells still adhere to the glandular cells. Three of the larger trichomes are more mature and essential oils secreted from the glandular cells of these trichomes have caused the cuticles covering them to separate from the cells and balloon outward, hiding the glandular cap cells below. This unfixed leaf was imaged with an FEI Quanta 200F SEM in environmental mode at Washington State University’s Franceschi Microscopy and Imaging Center. Scale bar = 150 µm.

Lighting up the World

Incandescent light bulbs are very inefficient in transforming energy into light. Since about 20% of the world’s total electricity consumption is used for lighting, a new and more efficient light source has to be developed. One solution is solid-state lighting, which employs light-emitting diodes (LEDs) made from semiconducting materials. The image shows the cathodoluminescence (CL) from an LED excited by the electron beam of an FEI Quanta 250. CL imaging helps to understand the properties of these LEDs and gives valuable insight into prevalent defects, such as the ring-shaped defect in the image, in order to improve the devices.
