Biography

Dr. Valerie Bowrin, BSc, Ph.D. in Department of Life Sciences from the University of the West Indies, St. Augustine. His study majors in Gel Electrophoresis, Bacterial Cell Culture, DNA Amplification, PCR, Cell Culture, Protein Purification, RNA Extraction, etc. He has published 8 articles in different journals in which the articles got good citations. He had worked on a project “Stem Tuberization in Manihot esculenta” which is quite informative and interesting.

  Inverse Oriented Stem Cuttings Generate Tuberous Stems in Cassava Manihot esculenta Crantz; An Alternative Sink Site
  Author(s): Judy Rouse-Miller*, Valerie Bowrin, Grace Sirju-Charran and Fedora Sutton
  
  Cassava (Manihot esculenta) is normally propagated by stem cuttings planted in a slanted, vertical or horizontal orientation. Axillary buds produce aerial shoot and adventitious roots are produced at the base (proximal end) of the cutting, some of which develop into tuberous roots. However, when cuttings are planted in an inverse, slanted or inverse straight orientation, the buried bases of the shoots which arise from underground buds swell. In this study, we determined that the stem swelling accumulates and store starch as do the tuberous root tubers. This phenomenon designated as inversion-induced stem tuberization, first detailed here, provides a system which could be used to study the roles of phytohormones and light... View More»
