Agenda
Annotation Consistency Exercise
Annotation consistency paper picked by TAIR: The MYB36 transcription factor orchestrates Casparian strip formation.
=Choice of paper-motivation
Capturing downstream targets and their resulting effects, importance of reading term definitions
Annotations requested to be restricted to Figures 1-4 only, to keep discussion manageable.
Summary of the paper
MYB36 is a transcription factor that controls where the machinery for deposition/biosynthesis of lignin is expressed The location of the machinery determines where the Casparian strip can form.
