Evolution of Plant Na⁺-P-Type ATPases: From Saline Environments to Land Colonization.

ABSTRACT: Soil salinity is one of the major factors obstructing the growth and development of agricultural crops. Eukaryotes have two main transport systems involved in active Na⁺ removal: cation/H⁺ antiporters and Na⁺-P-type ATPases. Key transport proteins, Na⁺/K⁺-P-ATPases, are widely distributed among the different taxa families of pumps which are responsible for keeping cytosolic Na⁺ concentrations below toxic levels. Na⁺/K⁺-P-ATPases are considered to be absent in flowering plants. The data presented here are a complete inventory of P-type Na⁺/K⁺-P-ATPases in the major branches of the plant kingdom. We also attempt to elucidate the evolution of these important membrane pumps in plants i
