TMEM37 and fungal infectious disease: However, since lyk2 mutants, but not lyk5‐2 or cerk1‐2, are not protected against B. cinerea after pre‐treatments with OG or flg22 and do not show priming of PR‐1 expression during fungal infection, LYK2 appears to mediate elicitor‐induced resistance also independently of chitin perception.
