T-DNA Insertion Lines with Altered Root System Architecture in Arabidopsis thaliana

Root system architecture of plants is a complicated phenotype that is pivotal to processes as fundamental as acquisition of water and nutrients, stress tolerance and anchorage in soil. This poster presents preliminary results of a search for genes that contribute to root system architecture in the model plant Arabidopsis thaliana. With the aid of microscopic observations, reverse and molecular genetics, we have identified genes functioning in different cellular pathways that contribute to Arabidopsis root system architecture. The study will expand our current understanding of how root systems grow and develop in plants, potentially facilitating the improvement of crop species.
