Lineage (from NCBI Taxonomy)

Fungi; Ascomycota; Leotiomycetes; Helotiales; Dermateaceae; Oculimacula


Found on cereals and grasses worldwide [5-9]. Its growth is favoured by cool damp weather and wet soil, and the temperature optimum for growth is 20-23 oC [10].

Interesting Features


Pseudocercosporella herpotrichoides causes foot-rot disease (also known as strawbreaker, eyespot or lodging disease) of cereals and grasses [10,11]. Two main pathotypes of the fungus are present in field populations: W-type and R-type. W-type is usually more pathogenic to wheat seedlings than to rye while R-type is equally pathogenic for these species [11 and references therein; 12]. These types are also distinguished by morphology and fungicide resistance characteristics.

Lignocellulose degradation

Cellulolytic and pectinolytic enzyme activities were detectable in culture media from Cercosporella herpotrichoides Fron grown at the expense of pectin or carboxymethylcellulose and malt extract [13]. Growth on wheat seedling cell walls elicited expression of cell wall degrading enzymes, including xylanase, arabinase and laminarinase with the latter two enzyme activities being constitutive rather than inducible [14]. Inducible xylanase activities were detected in culture media from 15 different strains of Pseudocercosporella herpotrichoides [15] . Pectinolytic and cellulolytic enzme activities were also detected in young wheat plants infected with Pseudocercosporella herpotrichoides var. herpotrichoides [16].

Host for recombinant protein production

Pseudocercosporella herpotrichoides has been used to express E. coli beta-glucuronidase [17].
