Genome-Wide Identification and Expression Assessment for the <i>Phosphate Transporter 2</i> Gene Family Within Sweet Potato Under Phosphorus Deficiency Stress.

ABSTRACT: Hainan's unique climate significantly contributes to soil acidification, causing phosphorus fixation into insoluble compounds, leading to phosphorus deficiency and reduced yield in sweet potatoes. The Phosphate Transporter 2 (PHT2) family, a group of trans-membrane phosphate transporters, is crucial for phosphate transport, distribution, and homeostasis regulation. Two PHT2 genes, IbPHT2-1 and IbPHT2-2, were first identified in sweet potato, and a phylogenetic analysis of 46 species showed high conservation of the IbPHT2 gene family throughout plant evolution. Tissue-specific expression patterns of IbPHT2 genes were determined in four sweet potato varieties using transcriptome analysis and RT-qPCR. The results demonstrated that IbPHT2 was pr
