Spent a whole semester reviewing a bunch of articles on plant development and physiology. Most of the experiments, if not all, were conducted on Arabidopsis thaliana. Among all the topics in plant developmental biology, I always found anther growth and dehiscence to be one of the more fascinating events in plant sexual development.
