25. Preservação de fungos fitopatogênicos habitantes do solo
A preservação de fungos fitopatogênicos por longos períodos de tempo é importante para que pesquisas possam ser realizadas a qualquer momento. Os fungos habitantes do solo são organismos que podem produzir estruturas de resistência em face de situações adversas, tais como ausência de hospedeiros e ou condições climáticas desfavoráveis para a su

26. Efeito da época de aplicação e dosagem do acibenzolar- S-metil na indução de resistência à murcha-de-Verticillium em cacaueiro
A resistência induzida representa uma medida promissora no manejo de doenças como a murcha-de-Verticillium do cacaueiro (Theobroma cacao), visto que possibilita a exploração de cultivares com boas características agronômicas, porém apresentando suscetibilidade a doenças. Grande avanço nessa área ocorreu com a utilização do éster S-metil do ácid

27. Variabilidade de regiões gênicas e espaçadoras do DNA ribossomal de Verticillium dahliae isolados de hospedeiros diferentes
A variabilidade genética de isolados de Verticillium dahliae oriundos de oliveira (Olea europaea) e de outros hospedeiros na Argentina e Brasil foi estimada através de PCR, usando primers específicos para a amplificação da região espaçadora intergênica do DNA ribossomal (IGS) e de uma porção do gene codificante para a subunidade menor do RNA riboss

28. Tratamento térmico solar da água para controle de fitopatógenos
Alguns microrganismos fitopatogênicos podem ser transportados pela água, que se constitui em importante e eficiente forma de disseminação. O controle de fitopatógenos pelo tratamento térmico da água infestada, utilizando a energia solar, constituiu o objetivo do trabalho. Quantificou-se a eficiência de um sistema automatizado de aquecimento solar des

29. PCR primers that allow intergeneric differentiation of ascomycetes and their application to Verticillium spp.
A pair of conserved PCR primers, designated NMS1 and NMS2, that amplify a region in the mitochondrial small rRNA gene region were designed for fungi belonging to the class Ascomycetes. These primers were tested with members of eight fungal genera (Aspergillus, Fusarium, Magnaporthe, Mycospharella, Neurospora, Saccharomyces, Sclerotinia, Verticillium) and 10

30. VdNEP, an Elicitor from Verticillium dahliae, Induces Cotton Plant Wilting
Verticillium wilt is a vascular disease of cotton. The causal fungus, Verticillium dahliae, secretes elicitors in culture. We have generated ∼1,000 5′-terminal expressed sequence tags (ESTs) from a cultured mycelium of V. dahliae. A number of ESTs were found to encode proteins harboring putative signal peptides for secretion, and their cDNAs were isolate

31. The Mechanism of Heterokaryotic Growth in VERTICILLIUM DAHLIAE
Heterokaryons of Verticillium dahliae, forced between complementary auxotrophs, were stable at 21° and resembled the wild type morphologically. In such heterokaryons the hyphal cells were predominantly uninucleate, and no nuclear migration from cell to cell was observed. Heterokaryosis was apparently confined to binucleate, interhyphal, anastomosed cells th

32. Interlaboratory Comparison of Methods To Quantify Microsclerotia of Verticillium dahliae in Soil
In a comparison of different methods for estimating Verticillium dahliae in soil, 14 soil samples were analyzed in a blinded fashion by 13 research groups in seven countries, using their preferred methods. One group analyzed only four samples. Twelve soil samples were naturally infested, and two had known numbers of microsclerotia of V. dahliae added to them

33. In vitro analysis of the role of glucose oxidase from Talaromyces flavus in biocontrol of the plant pathogen Verticillium dahliae.
Culture filtrates from Talaromyces flavus grown on glucose contained high levels of glucose oxidase activity, while culture filtrates from T. flavus grown on xylan contained negligible glucose oxidase activity. Culture filtrates from T-flavus grown on both media contained complex protein profiles. However, only culture filtrates from T. flavus grown on gluco

34. Elemental Sulfur and Thiol Accumulation in Tomato and Defense against a Fungal Vascular Pathogen1
The occurrence of fungicidal, elemental S is well documented in certain specialized prokaryotes, but has rarely been detected in eukaryotes. Elemental S was first identified in this laboratory as a novel phytoalexin in the xylem of resistant genotypes of Theobroma cacao, after infection by the vascular, fungal pathogen Verticillium dahliae. In the current wo

35. Stimulation of Sanguinarine Production by Combined Fungal Elicitation and Hormonal Deprivation in Cell Suspension Cultures of Papaver bracteatum1
Fungal elicitor preparations from either homogenized mycelia of Dendryphion penicillatum (Cda.) Fr., a specific pathogen of Papaver species, or conidia of Verticillium dahliae Kleb., a general pathogen, were added to 14-day-old suspension cultures of Papaver bracteatum. Plant tissue cultures were grown either in the presence or absence of 0.1 milligram of 2,

36. Plant-Dependent Genotypic and Phenotypic Diversity of Antagonistic Rhizobacteria Isolated from Different Verticillium Host Plants
To study the effect of plant species on the abundance and diversity of bacterial antagonists, the abundance, the phenotypic diversity, and the genotypic diversity of rhizobacteria isolated from potato, oilseed rape, and strawberry and from bulk soil which showed antagonistic activity towards the soilborne pathogen Verticillium dahliae Kleb. were analyzed.
