  1. Scenario 4 Analysis: Discovery of coregulated genes What follows is a simulation of the proposed graphical interface. As you go through the simulation please consider what capabilities you would want to serve your research and annotation interests. A narrative to help you go through the simulation appears in a red-bordered box, such as the one below. To begin:1. Click on Slide Show, (on the upper toolbar)2. Click View Show3.

  2. How do cells control response to light? What genes are related to the adaptation to high light? Look for: • Gene present in Prochlorococcus MED4 MED4 is naturally adapted to grow in high light. • Ortholog absent in Prochlorococcus MIT9313 MIT9313 is naturally adapted to grow in low light • Ortholog present in Synechocystis PCC 6803 Reason will become apparent in a moment • Synechocystis PCC 6803 ortholog responds to high light Gene turns on by factor > 2 in response to high light Continue
