In molecular biology, the cerato-platanin family of proteins includes the phytotoxin cerato-platanin (CP) produced by the AscomyceteCeratocystis platani. CP homologs are also found in both the Ascomycota and the Basidiomycota branches of Dikarya.[1] This toxin causes the severe plant disease: canker stain. This protein occurs in the cell wall of the fungus and is involved in the host-pathogen interaction and induces both cell necrosis and phytoalexin synthesis which is one of the first plant defense-related events. CP, like other fungal surface proteins, is able to self-assemble in vitro.[2] CP is a 120 amino acid protein, containing 40% hydrophobicresidues. It is one of the rare examples of protein in which contains a Hopf link.[3] The link is formed by covalent loops - the pieces of protein backbone closed by two disulphide bonds[4] (formed out of four cysteine residues). The N-terminal region of CP is very similar to cerato-ulmin, a phytotoxic protein produced by the Ophiostomaspecies belonging to the hydrophobin family, which also self-assembles.[5]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
