The role of organelle genomes in plant adaptation Time to get to work!

That organellar genome variation can play a role in plant adaptation has been suggested by several lines of evidence, including cytoplasm capture, cytoplasm effects in local adaptation and positive selection in a chloroplast gene. Indepth analysis and better understanding of the genetic basis of plant adaptation is becoming a main objective in plant science. Arabidopsis thaliana has all the required characteristics to be used as a model for obtaining knowledge on the mechanisms underlying the role of organelles in plant adaptation. The availability of the appropriate tools and materials for assessing organelle genetic variation will open up new opportunities for developing novel breeding strategies.
