Vaccinium project

Vaccinium vitis-idaea L. in Newfoundland

Vaccinium vitis-idaea L. in Newfoundland

We have received funds from the Research and Development Corporation of the Government of Newfoundland (RDC Ignite Grant) to conduct a project entitled “Knowledge of the factors affecting antioxidant properties in partrideberry will lead to a more profitable berry harvest in Newfoundland”

The main objectives of this project are:

  1. Estimate the total phenolics and antioxidant capacity of wild partrideberry (Vaccinium vitis-idaea L.) populations distributed across 10 ecoregions of Newfoundland and Labrador. Environmental effects on these biochemical properties will be elucidated. Download publication here: cjb-2016-0041pr
  2. Using next generation DNA sequencing technology, we will address questions like: Are geographically proximate populations also genetically closer? Do genetically close populations contain similar biochemical properties? Is the variation in chemical composition determined by genotype or by the environment?
  3. DNA sequencing will reveal thousands of mutations among wild populations. Based on sequence similarity to available protein sequences in the database of the U.S. National Center for Biotechnology Information, we will link these mutations to genes and their tentative metabolic pathway, paying attention to those related to the synthesis of phenolics.

Two MSc students, Zobayer Alam and Hugo Morales are conducting this research.
