Potassium (K+) is an essential macronutrient that supports plant growth, development, and stress resilience. SHAKER-type K+ channels play a central role in K+ uptake, transport, and homeostasis. Despite their well-documented functions in model plants, little is known about this gene family in garlic (Allium sativum). In this study, nine Shaker genes were classified into three main subfamilies, including AKT, KAT, and SKOR. Exon-intron patterns varied across subgroups, with SKOR and KAT3 members showing higher structural complexity. Gene expression profiling across diverse tissues highlighted strong organ-specific activity, particularly in bulbs, leaves, and flowers. Notably, AsKAT2 and AsSKOR1 displayed high expression under normal conditions. Under virus-infected conditions, several genes were transcriptionally responsive. These results provide new insights into the molecular characteristics and expression behavior of SHAKER channels in garlic and lay the groundwork for future studies on their physiological roles in nutrient transport and stress response.
