A putative cyclic peptide efflux pump encoded by the TOXA gene of the plant-pathogenic fungus Cochliobolus carbonum
Article Abstract:
The TOXA gene of the plant-pathogen fungus, Cochliobolus carbonum, encodes an HC-toxin efflux pump which plays a role in self-protection against HC-toxin. The gene is present only in the fungal isolates that make HC-toxin, and it occurs as two linked copies. TOXA occurs close to HTS1, the gene found in HC-toxin making fungal isolates, that codes for the enzyme necessary for the synthesis of HC-toxin. The amino acid sequence of TOXA gene is discussed.

Targeted mutants of Cochliobolus carbonum lacking the two major extracellular polygalacturonases
Article Abstract:
Research was conducted to examine the targeted mutants of Cochliobolus carbonum lacking the two major extracellular polygalacturonases (exoPG). The purification of the exoPG activity of C carbonum and the cloning of its gene, PGX1, was also performed. Double pgn1/pgx1 mutant strain was developed by crossing. The continued growth of the pgn1/pgx1 mutant strain on pectin could be attributed to one or more of PG residual activities.

A putative branched-chain-amino-acid transaminase gene required for HC-toxin biosynthesis and pathogenicity in Cochliobolous carbonum
Article Abstract:
Results reveal that TOXF gene has a role in the HC-toxin production and pathogenicity of Cochliobolus carbonum. The amino acid sequence data show homology to branched-chain-amino-acid transaminases from other species.
