Teaching Tools in Plant Biology is an online educational resource published by The Plant Cell and the American Society of Plant Biologists. Each Teaching Tool includes a set of about 100 PowerPoint slides, a review article suitable for undergraduates with hyperlinked reading lists, and a teaching guide that includes learning objectives and discussion questions. Each article is peer-reviewed and incorporates broad introductory materials as well as some in-depth analysis of key experiments, so can be tailored for use with a variety of students, and each is updated annually. Topics include Leaf Development, Epigenetics, Phytohormones, Why Study Plants and Genetic Improvements in Agriculture. Teaching Tools are available to personal or institutional subscribers of The Plant Cell, but the first six articles, including Leaf Development and Epigenetics, do not require a subscription. We also have a FaceBook page on which we highlight timely topics of interest to teachers of plant development, genetics, molecular and cell biology and physiology. Please have a look and use any materials you like. We’re always happy for feedback! Send comments to email@example.com.
