  • Drosophila

    Drosophila are small flies, typically pale yellow to reddish brown to black, with red eyes. Many species, including the noted Hawaiian picture-wings, have distinct black patterns on the wings. The plumose (feathery) arista, bristling of the head and thorax, and wing venation are characters used to diagnose the family.

  • Arabidopsis

    Wild-type and transgenic Arabidopsis plants expressing miR156, a microRNA that promotes juvenility and increases the rate of leaf initiation

  • Archaea

    Haloferax volcanii motility mutants stab-inoculated on a 0.3% agar motility plate. The “halos” and “rings” likely reflect the motility of this archaeon following gradients of attractant or repellent chemicals. 

  • Sensation

    The sensations of pain, itch, and touch using genetics and neurobiology.

  • ERK1/2 signaling pathway

     ERK1/2 signaling pathway regulates exocytosis and tumor invasion through phosphorylation of the exocyst complex.
