[Wolfgang Schmidt] Iron acquisition strategies in land plants: Not so different after all

Plants have evolved two phylogenetically separated and elaborately regulated strategies to mobilize iron from the soil, featuring mechanisms which are thought to be mutually exclusive. Louis Grillet and Wolfgang Schmidt use publicly available data obtained from the model species rice (Oryza sativa) to unveil similarities and incongruities between co-expression networks derived from transcriptomic profiling of iron-deficient rice and Arabidopsis plants. This approach revealed striking similarities in the topographies of the resulting co-expression networks with relatively minor deviations in the molecular attributes of the comprised genes, which nonetheless lead to different physiological functions.
