One of my hobbies lately has been to get either RNA seq or microarray data from GEO and do quick analyses. Not only is this fun, I can find good examples to use for teaching biology.
One of these fun examples comes from some Arabidopsis data. In this experiment, some poor little seedlings were taken out of their happy semi-liquid culture tubes and allowed to dry out. This simulated drought situation isn't exactly dust bowls and hollow-eyed farmers, but the plants don't know that and most likely respond in a similar way.
We can get a quick idea of how the plants feel about their situation…
