| Intereses de Educación | | Responsible for teaching the following courses: Biol 3300 (Genetics),Biol 4039 (Plant Biotechnology) and Biol 5018 (Plant Physiology) | | | | Intereses de Investigación | | Our research focuses on using molecular biology tools and tissue culture techniques to study plants. One project in the lab studies the environmental influence on the expression level of genes in the cyanogenic glucoside synthesis, breakdown and re-assimilation pathways of cassava. Similar quantitative study is also being conducted to measure the expression levels of the same genes between different cassava varieties that naturally contain low, medium and high levels of cyanide, respectively. A newly identified gene of the cyanide re-assimilation pathway is the focus of another project which aims to simultaneously reduce cyanogen content and increase the protein level in cassava using transgenic strategies. We are also exploring the function of this novel gene in Arabidopsis thaliana as well. Another main research focus of the lab is the use of SSR molecular markers to assess the genetic diversity of Puerto Rican cassava germplasm. This germplasm is being analyzed for its diversity as well as their relationship to known varieties from Central and South America, Africa and Asia. | | |
