In-Depth Genomic and Transcriptomic Analysis of Five K⁺ Transporter Gene Families in Soybean Confirm Their Differential Expression for Nodulation.

ABSTRACT: Plants have evolved a sophisticated network of K⁺ transport systems to regulate growth and development. Limited K⁺ resources are now forcing us to investigate how plant demand can be satisfied. To answer this complex question, we must understand the genomic and transcriptomic portfolio of K⁺ transporters in plants. Here, we have identified 70 putative K⁺ transporter genes from soybean, including 29 HAK/KT/KUP genes, 16 genes encoding voltage-gated K⁺ channels, 9 TPK/KCO genes, 4 HKT genes, and 12 KEA genes. To clarify the molecular evolution of each family in soybean, we analyzed their phylogeny, mode of duplication, exon structures and splice sites, and paralogs. Additionally, ortholog clustering and syntenic analysis across five othe
