Colletotrichum higginsianum is a hemibiotrophic fungus. This means that in order for this fungus to obtain energy, it "first establishes a biotrophic interaction by evading the plant’s defense mechanisms and later switches to a necrotrophic phase, in which it kills the host cells and feeds on them.
Some chemical defenses once thought to be produced by the plant have since been shown to be synthesized by endophytic fungi. The chemical basis of insect resistance in endophyte-plant defense mutualisms has been most extensively studied in the perennial ryegrass and three major classes of secondary metabolites are found: indole diterpenes, ergot alkaloids and peramine.
Some host specialist entomopathogenic fungi have even evolved mechanisms of behavioral manipulation (e.g. Ophiocordyceps unilateralis - Zombie ant fungus) of their hosts. [7] These fungi hijack the insect nervous systems using various secondary metabolites and manipulate insect behavior to move the infected insect to a place which is ...
Defensins are small cysteine-rich cationic proteins across cellular life, including vertebrate [1] and invertebrate [2] animals, plants, [3] [4] and fungi. [5] They are host defense peptides, with members displaying either direct antimicrobial activity, immune signaling activities, or both.

A diagram showing the infecting structures and effector delivery strategies of a model hemibiotrophic pathogen, Phytophthora infestans. Fungal effectors are proteins or non-proteinaceous molecules (such as RNAs or small molecules) secreted by pathogenic fungi into a host organism in order to modulate the host's immune response.
