Plants have evolved multiple complex mechanisms enabling them to adapt low nitrogen (LN) stress via increased use efficiency (NUE) as deficiency in soil is a major factor limiting plant growth and development. However, the adaptive process evolutionary roles of LN tolerance-related genes plants remain largely unknown. In this study, we resequenced 191 watermelon accessions examined their phenotypic differences related tolerance. A gene ClSIK1 encoding serine/threonine protein kinase involved response was identified on chromosome 11 using genome-wide association study RNA-Seq analysis. According functional analysis, overexpression can increase root area, total biomass, NUE tolerance by manipulating nitrogen-metabolized genes. Interestingly, desirable LN-tolerant haplotype
