Chemical treatment of papaya seeds aiming at long-term storage and control of damping off
O tombamento é uma doença de viveiro de grande importância econômica na cultura do mamoeiro e o tratamento de sementes pode ser uma medida eficaz para seu controle. Objetivou-se, neste trabalho, avaliar a qualidade de sementes de mamão, tratadas com fungicidas, em formulação pó molhável, e armazenadas sob duas condições de acondicionamento (embalagens) e de ambiente. Adicionalmente, avaliou-se ...
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 کاملPathogenicity and Diversity of Vegetative Compatibility of Fusarium Verticillioides
Pathogenicity of 10 Fusarium verticillioides isolates, originated from grain of wheat (five isolates) and maize (five isolates), were studied under greenhouse conditions. Based on different parameters of the pathogenicity estimate (a scale for % of nonemerged plants, % of survived plants, plant vigour — the growth and dry weight of roots and epicotyls and disease severity) it was determined tha...
متن کاملPAC1, 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 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...
