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.
