Sodium (Na) Uptake

  • Gyanendra Nath Mitra

Abstract

While Na+ is not an essential nutrient for all plants, it is essential for halophytes, which accumulate salt in vacuoles to maintain turgor and growth. A few of the C4 plants (except corn and sorghum) need Na+ essentially for specific functions, such as in the concentration of CO2. High-affinity Na+ uptake probably occurs in most of the land plants. Na+ can be beneficial to plants under conditions of K+ deficiency. Na+ can undertake osmotic functions, reduce the total K+ requirements and improve growth when the lack of K+ is a limiting factor.
