Disease resistance has been bred into many crop varieties for bacterial and fungal pathogens. Wheat cultivar, has been bred for resistance to diseases like leaf and stripe rust, a fungal disease, that causes a rust like layer to appear on the parts affected. Brassica is resistant to white rust, a disease that causes a white colored rust like layer to appear on plant tissues or causes white blisters on the plant tissues that are above the ground. Cultivars of cauliflower are resistant to black rot. Cowpea is resistant to bacterial blight.
