Mijitaba Hamissou, Ph.D.

Professor of Biology
128D Martin Hall

My research areas are the investigation of some molecular aspects of somatic embryogenesis and the cryobiology of plants cells. Knowing that cell lines in continuous culture are prone to genetic drift and that all cell cultures are susceptible to microbial contamination, being able to keep cell lines is a valuable resource in plant cell and tissue culture laboratory. We generate callus from Arabidopsis thaliana, Nicotiana tobacum and Capsicum annum to initiate liquid culture of cells for use in a variety of low temperature experiments and embryogenesis.
Other aspects of my research include the investigation of some biologically active compounds in several plants including pokeweed, Phytolacca Americana, moringa, Moringa Oleifera, tigernut, Cyperus esculentu, and chili pepper, Capsicum annum
