PAC1, a pH-regulatory gene from Fusarium verticillioides.
Fumonisins are a group of mycotoxins that contaminate maize and cause leukoencephalomalacia in equine, pulmonary edema in swine, and promote cancer in mice. Fumonisin biosynthesis in Fusarium verticillioides is repressed by nitrogen and alkaline pH. We cloned a PACC-like gene (PAC1) from F. verticillioides. PACC genes encode the major transcriptional regulators of several pH-responsive pathways...
متن کاملGenomic analysis of Fusarium verticillioides.
Fusarium verticillioides (teleomorph Gibberella moniliformis) can be either an endophyte of maize, causing no visible disease, or a pathogen-causing disease of ears, stalks, roots and seedlings. At any stage, this fungus can synthesize fumonisins, a family of mycotoxins structurally similar to the sphingolipid sphinganine. Ingestion of fumonisin-contaminated maize has been associated with a num...
متن کاملFunctional characterization of Fusarium verticillioides CPP1, a gene encoding a putative protein phosphatase 2A catalytic subunit.
Fusarium verticillioides produces the mycotoxin fumonisin B(1) (FB(1)) on maize kernels. In this study, we identified a putative protein phosphatase gene CPP1 in F. verticillioides, and investigated its role in FB(1) regulation. Previous work has shown that CPP1 expression is elevated in an FB(1)-suppressing genetic background. Thus, we hypothesized that CPP1 is negatively associated with FB(1)...
متن کاملGenetic and morphological characterization of a Fusarium verticillioides conidiation mutant.
Enteroblastic phialidic conidiation by the corn pathogen Fusarium verticillioides (teleomorph Gibberella moniliformis) produces abundant, mostly single-celled microconidia in distinctive long chains. Because conidia might be critical for establishing in planta associations, we characterized a spontaneous F. verticillioides conidiation mutant in which phialides were incapable of enteroblastic co...
متن کاملCareful with That Axe, Gene, Genome Perturbation after a PEG-Mediated Protoplast Transformation in Fusarium verticillioides
Fusarium verticillioides causes ear rot disease in maize and its contamination with fumonisins, mycotoxins harmful for humans and livestock. Lipids, and their oxidized forms, may drive the fate of this disease. In a previous study, we have explored the role of oxylipins in this interaction by deleting by standard transformation procedures a linoleate diol synthase-coding gene, lds1, in F. verti...
