Welcome to PHT !

Phosphorus (P) is an essential macroelement for plant growth and development, playing important roles in plasma membrane maintenance, nucleic acid synthesis, energy metabolism and enzyme regulation. P deficiency strongly affects physiological and biochemical reactions during the growth and development of plants. PHT (phosphate transporter), a member of the major facilitator superfamily (MFS), is located on the plasma membrane. Based on differences in structure and subcellular localization, all Pi transporters from dicotyledons and monocotyledons are divided into four subfamilies, PHT1, PHT2, PHT3 and PHT4, which are mainly located in cell membrane, chloroplast, mitochondria and Golgi apparatus, respectively.
