The Role of JAR1 in Insect Feeding Response
Date of this Version
Plant and Soil Sciences eLibrary (PASSeL) Lesson
Summary: This lesson reveals both the process and the power of conducting experiments with jar1, an Arabidopsis mutant that is insensitive to the hormone jasmonic acid (JA). You will meet a graduate student conducting research under the guidance of an expert in JA biology.
After completing this activity students will be able to:
- Explain why jasmonic acid (JA) is a plant hormone.
- Describe why arabidopsis plants with a mutation in a gene (JAR1) involved in JA response are useful subjects in experiments designed to understand JA control of plant biology.
- Interpret data from experiments designed to test hypotheses about the role of the JAR1 gene in plant response to insect feeding.
- Design future experiments to test hypotheses on the genetic control of plant response to JA.
