Protein Kinase A Regulates Hyphal Growth by Relieving the Interaction of MoSfl1 with the Cyc8-Tup1 Co-repressor in Magnaporthe oryzae
… appressorium turgor generation, and invasive growth. Two genes in M. oryzae named CPKA and CPK2 encode the catalytic subunits of cAMP-dependent protein kinase A. Previous studies have shown that deletion of CPKA failed to block response to exogenous cAMP, suggesting the involvement of CPK2 in …

A Study of the Effect of Herbicides on Mycorrhizae Associated With Native Warm Season Grass
… in sand. After 26 days incubation the dark, hyphal growth was measured. The herbicides reduced hyphal growth.

THE ROLE OF BACTERIA AND ß-LACTAM ANTIBIOTICS IN CANDIDA ALBICANS INFECTION
… been reported as potent inducers of C. albicans hyphal growth. Here, we report that β-lactam antibiotics cause bacteria to release large quantities of hyphal-inducing PGN subunits into the environment, including culture media and the GI tract of mice. Of high importance, massive hyphal growth in …

Identification of a Novel Link between the Motor Proteins Dynein and Kinesin-1
… fungi, these motors are important for the hyphal growth, which is characterized by localized extension at the tip of the apical hyphal cell. This type of growth requires the movement of a large number of vesicles from and to the hyphal tip in order to support the continuous addition of new …

Isolation and identification of a phytoalexin from sugarcane
… of C. falcatum, and appears to inhibit further hyphal growth. Resistant sugarcane cultivars reportedly produce the red material more quickly after infection than susceptible cultivars. Previous workers had identified luteolinidin, an anthocyanidin, in extracts of infected sugarcane and suggested …

The Cell Wall Integrity-Associated Map Kinase Homolog, AbSlt2 in the Necrotrophic fungus Alternaria brassicicola is Required for Pathogenicity of Brassicas
… in the mutants compared to the wild type. During growth in various liquid and solid media, the abslt2 mutants displayed slightly aberrant hyphal growth and were unable to develop at the same rate as wild type. Furthermore, scanning electron microscopy (SEM) analysis revealed the abslt2 mutants …

The Role of G-Protein Signaling in Pathogenesis in Cercospora zeae-maydis
… of maize worldwide. C. zeae-maydis orients hyphal growth towards stomata (stomatal tropism) and forms infectious structures (appressoria) that are necessary for successful infection. Although some genes involved in pathogenesis in C. zeae-maydis have been identified, the molecular mechanisms …

Discovery of novel antibacterial and antitubercular compounds using chemical genetics and computational approach targeted at phospholipid biosynthesis
… Alteration of pss expression affects the overall growth and morphology of S. coelicolor (i.e. hyphal growth, branching, septation and sporulation) therefore verified the potential of these proteins as drug targets. Although, the early stage "hit identification" approach using a modest collection …

Immuno-gluorescence study of five zygomycetous fungi with two chitin-binding probes
… to be no involvement of chitinase during apical hyphal growth or new branch initiation in any of the fungi tested despite mild proteolysis and permeabilization of the cell surface prior to labelling. Binding with WGA revealed similar patterns of fluorescence to that of chitinase localization but …

Interaction Between Soybean and Phytophthora Sojae
… early colonization stages of pathogenesis, with growth of hyphae of the pathogen being reduced. The objectives of this research were: (1) to isolate and identify races of P. sojae in Illinois soybean fields; (2) to determine the inheritance of resistance to P. sojae in the soybean PI 567574A; and …

The streptomyces cytoskeletal protein (Scy) is a key component of the tip organising centre for polarized growth in streptomyces coelicolor
… cytoskeletal proteins. Streptomyces coelicolor hyphal growth occurs through apical extension where new cell wall material is placed at the tips. This growth is driven in part by the cytoskeletal protein DivIVA. Here we characterise a novel Streptomyces cytoskeletal protein, Scy, encoded by the …

Establishment and regulation of polar growth in Streptomyces
… the regulatory mechanisms controlling polar cell growth in prokaryotes. In evolutionary terms, the most ancient form of polar growth is found in the branching hyphae of the filamentous bacteria Streptomyces, and it is clear that the essential coiled-coil protein DivIVA, which forms part of a …

Biofiltration of volatile organic compounds using fungal-based bioreactors
… foam medium, which was found to favor hyphal growth in the internal pores of the packing. To reduce the 7- to 10-day start-up period typically observed in fungal bioreactors, surfactants were evaluated as fungal spore activators. Results showed that Tween 20, a nonionic surfactant, …

The influence of magnesium ions on the growth and metabolism of <i>Saccharomyces cerevisiae</i>
The growth response of batch culture of <i>Saccharomyces cerevisiae</i> to magnesium-limitation, under conditions of micro-aerophillic glucose-repression, was shown to be hyperbolic, thus indicating a Monod relationship. The maximum growth rate was found to be 0.20hrs<sup>-1</sup> whilst …

Detection of viable urediniospores, morphological characterization in resistant and susceptible genotypes, and germ tube anastomosis of Phakopsora pachyrhizi
… susceptible cultivar Williams 82 had extensive hyphal growth in the mesophyll cells. The soybean cultivar UG5 conferred complete resistance, and plant introductions 567102B and 224268, which were classified as having incomplete resistance, had extensive necrosis of the mesophyll cells. These …

Anti-candida and Anti-virulence Activity of Essential Oils and Their Components
… the emergence of further resistance, inhibiting growth and virulence factors in fungal cells represents a good alternative for the development of new antifungal drugs. Recently, there has been a resurged interest in essential oils and their active components, in relation to their pharmacological …
