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,
