Many of the genes in these two modules encode proteins related to responses to infections and defenses against plant pathogens, including the receptor-like protein kinases RLK5 (Ibat.Brg.05B_G013520) and RLK7 (Ibat.Brg.08C_G006740), the LRR receptor-like serine/threonine protein kinase SERK1 (Ibat.Brg.06B_G025950), and the serine/threonine protein kinase 11-interacting protein-like STK11IP (Ibat.Brg.10A_G016990). The gene discussed is MAP2K4; the disease is infection.
