NtPHT2;1 promotes tobacco growth by integrating chloroplast phosphate utilization with photosynthesis and carbon-nitrogen metabolism.
Phosphorus (P) is an essential macronutrient required for plant growth and productivity, and its uptake and distribution are mediated by members of the phosphate transporter (PHT) family. Among them, the transporter PHT2.1 has been implicated in chloroplast phosphate homeostasis; however, its role in coordinating plant...
