5 Arabidopsis as a model plant What is the role of Arabidopsis now that we have lots of plant genome sequences? –Original reasons for using Arabidopsis still hold true –New genomes make it easier to apply results from Arabidopsis to other plants –More knowledge and tools More useful

6 Arabidopsis as a model plant What is the role of Arabidopsis now that we have lots of plant genome sequences? –Original reasons for using Arabidopsis still hold true –New genomes make it easier to apply results from Arabidopsis to other plants –More knowledge and tools More useful The era of genome-hopping is upon us
