Natural variation in potassium deficiency responses among Arabidopsis thaliana accessions.

ABSTRACT: Potassium (K) is a key nutrient essential for plant growth, and its deficiency induces various adaptative responses in plants; however, the mechanisms underlying these responses remain unclear. In the present study, we explored the natural variation in K deficiency responses among 100 naturally occurring accessions of Arabidopsis thaliana and then performed a genome-wide association study (GWAS) to identify the genetic loci associated with these responses. All 100 Arabidopsis accessions showed significant differences in several traits under K deficiency, including shoot and root growth, photosynthetic activity, and inorganic ion contents. The results indicated that the reduction in K+ content due to K deficiency was correlated more significantly with decreases in the number and total lengt
