Potassium and sodium uptake systems in fungi. The transporter diversity of Magnaporthe oryzae

► Fungi are furnished with four types of K+ transport systems, TRK and HAK transporters, and ACU and PAT ATPases. ► The distribution of these transport systems is highly variable across fungal species. ► The ACU ATPases of Magnaporthe oryzae mediate high-affinity Na+ uptake in addition to K+ uptake.
