Toxin-deficient mutants from a toxin-sensitive transformant of Cochliobolus heterostrophus.

Genetics - 1 Jul 1994

Yang G, Turgeon B G, Yoder O C

Abstract excerpt

Tox1 is the only genetic element identified which controls production of T-toxin, a linear polyketide involved in the virulence of Cochliobolus heterostrophus to its host plant, corn. Previous attempts to induce toxin-deficient (Tox-) mutants, using conventional mutagenesis and screening procedures, have been unsuccessful. As a strategy to enrich for Tox- mutants, we constructed a Tox1+ strain that carried the...
