Gene Expression Modulation of Two Biosynthesis Pathways via Signal Transduction in Cochliobolus heterostrophus
G-protein-linked pathways have evolved to allow responses to extracellular agonists (hormones, neurotransmitters, odors, chemoattractants, light and nutrients) in eukaryotic cells, ranging from simpler systems, including yeasts, filamentous fungi and slime molds, to more complex organisms, such as mammals. Although the role of G-protein and mitogen-activated protein kinase (MAPK) in filamentous...
متن کاملIron Specifically Protects Corn Protoplasts from T-Toxin of Cochliobolus heterostrophus.
Ferric ion reduced the damaging effects of T-toxin, a series of linear beta-polyketols produced by the pathogenic fungus Cochliobolus heterostrophus, on leaf mesophyll protoplasts from susceptible T-cytoplasm corn. Of nine metals tested, only ferric and ferrous ions had this effect. Despite the presence of 12 available oxygen atoms in each T-toxin molecule, there was no evidence for the formati...

متن کاملToxin-deficient mutants from a toxin-sensitive transformant of Cochliobolus heterostrophus.
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 ...
متن کاملChLae1 and ChVel1 Regulate T-toxin Production, Virulence, Oxidative Stress Response, and Development of the Maize Pathogen Cochliobolus heterostrophus
LaeA and VeA coordinate secondary metabolism and differentiation in response to light signals in Aspergillus spp. Their orthologs, ChLae1 and ChVel1, were identified in the maize pathogen Cochliobolus heterostrophus, known to produce a wealth of secondary metabolites, including the host selective toxin, T-toxin. Produced by race T, T-toxin promotes high virulence to maize carrying Texas male st...
