Abstract : Fungi are far more complex organisms than viruses or bacteria and can developed

numerous diseases in plants that cause loss of big portion of the crop every year. Plants have

developed various mechanisms to defend themselves against these fungi which include the

production of low molecular weight secondary metabolites, proteins and peptides having

antifungal activity. In this review, brief information like biochemistry, source, regulation of gene

expression, mode of action of defense mechanism of various pathogenesis-related proteins is

given. Proteins include pathogenesis-related protein 1, â-glucanases, chitinases, chitin binding

protein, thaumatine like protein, glycine-histidine rich proteins, ribosome inactivating protein,
