Plaza, a resource for plant comparative genomics, has a lot more than meets the eye at first. Currently the database has comparative tools and data for nearly 2 dozen plants including monocots, dicots, mosses and algae. There are some obvious tools and data from the homepage, but I suggest you take a look at the documentation and tutorials, you’ll find there is a lot more once you start delving into it. In this tip, I’m going to walk though getting phylogeny of a gene family from a specific clade to illustrate that there is a lot here that you might not see at first.
