Plant cell biology. Cytoskeleton and cell motility. Early effects of Nod factors on legume root development. Early responses to gravity and microgravity by plant cells. Video microscopic image development.
Video Microscopy (BO 595V) is taught in the spring in even years and yields 4 credits in Botany and 2 credits for Biotechnology Minor. Plant Cell Biology is taught in the spring in odd years.
Short courses with instruction about various types of microscopy are offered through the Cellular and Molecular Imaging Facility at announced times.
