The ab- normal condition produced in plants by fungous and bacterial parasites and by other agents is known as a dis- ease. On some plants, the disease takes the form of a leaf-spot or a blight; in others swellings or galls are produced. Cankers on branches of trees and on stems of herbaceous plants are produced by fungi living in the affected tissue. The well-known fire- blight and blight-canker of pears are caused by bacteria. The rots of fruits and vegetables are largely produced by fungi or bacteria. 196. Some parasites spring from the ground (Figs. 131, 132), as other plants do, but they are parasitic on the roots of their hosts. Some parasites may be partially parasitic and partially saprophytic. Many (perhaps most) of these root-saprophytes are aided in securing their food by soil fungi, which spread their delicate threads over the root-like branches of the plant and act as intermediaries. 135.
