<jats:title>Significance</jats:title> <jats:p> Northern corn leaf blight (NCLB) is one of the most devastating fungal diseases of maize. The <jats:italic>Htn1</jats:italic> disease resistance gene confers quantitative field resistance against most NCLB isolates. Here we show that <jats:italic>Htn1</jats:italic> encodes a putative wall-associated receptor-like kinase (RLK). RLKs act as important components of the first tier of the plant innate immune system by perceiving pathogen- or host-derived elicitors on the cell surface. RLKs are often associated with resistance to nonadapted pathogens and are a component of nonhost resistance. Our work demonstrates that the Htn1-RLK plays an important role in host resistance against adapted fungal pathogens. </jats:p>
