Combatting the Southern Pine Beetle

RNAi, Science Policy, and Working with Indigenous Communities

Combatting the Southern Pine Beetle


 

Abstract

This case study begins with the story of a young biologist who belongs to an Indigenous community in rural Virginia where southern pine beetles (Dendroctonus frontalis) are wiping out the pine trees sacred to her native culture. She wonders if RNA interference (RNAi) technology could be used to inhibit the growth of this invasive species. Students are tasked with designing an RNAi system to specifically inhibit the growth and spreading of the beetles while following best practices for Indigenous traditional ecological knowledge (ITEK). Students explore various RNAi-based delivery techniques for forest management and design experiments for testing the options. Students conclude the case by writing a summary report explaining how they could integrate ITEK into their research of RNAi to control southern pine beetles. This case study is appropriate for any course that incorporates RNAi, including molecular biology, genetics, cell biology, or biochemistry, although the incorporation of primary literature in the case makes it most suitable for upper-level students.

Overview

Objectives

  • Determine appropriate methods used to introduce siRNAs/miRNAs (micro RNAs) into plant cells, such as agrobacterium-mediated transformation.
  • Model RNAi vectors, including promoter, origin of replication, hairpin loop, and antibiotic resistance elements.
  • Design forward/reverse genetics experiments using RNAi to study gene function.
  • Design research questions that can be addressed using RNAi in plant biology, including the development of plants with desired traits.
  • Critique benefits and concerns associated with using RNAi in agriculture, considering regulatory frameworks and ethical considerations.
  • Identify social, economic, and biological impacts of introducing RNAi into a community.
  • Develop communication skills for translating research to various audiences.
