Interactions between Cucumber mosaic virus proteins and host proteins
… is counterproductive to CMV since this triggers antibiosis against aphids and stimulates resistance mechanisms by AGO2. The CMV 1a protein (a replicase component) is able to moderate antibiosis induction by the 2b VSR. This ensures that aphid vectors are deterred from feeding but not poisoned …

European corn borer resistance in sorghum compared with maize
… is resistance to leaf feeding (a high level of antibiosis against 1st- and 2nd-instar larvae). Dried-ground leaves (substituted for wheat germ in a meridic diet) of resistant genotypes of sorghum and maize had no deleterious effect on survival and development of ECB larvae compared with a diet …

Alternativas de manejo de áfidos limitantes de la producción de alfalfa en el Sudoeste bonaerense
… evaluaron la resistencia por antixenosis y por antibiosis y la tolerancia. Los cultivares ACA 605, Brava y CW 194 resultaron antixénoticos. Los cultivares CW 194, CW 1010, EBC 90, Pampa Flor, Sirosal y Venus, poseen resistencia por antibiosis. Finalmente, Carmina, CW 194, CW 830 y SPS 6550 …

Soybean Resistance and Defense Responses Against Aphis Glycines
… glycines was studied by (i) characterizing the antibiosis type of resistance, (ii) mapping the aphid resistance gene(s), (iii) investigating the potential factors associated with aphid resistance, and (iv) identifying resistance-related defense responses. Antibiosis in the resistant soybean …

The investiation into the synthesis of 2,5-Diphenyloxazole in Streptomyces polyantibioticus SPR
… Province, South Africa. It exhibited antibiosis against M. tuberculosis H37RvT, prompting interest in its antibiotic production. An antibiotic produced by S. polyantibioticus SPRT was isolated and its structure determined by nuclear magnetic resonance (NMR) and X-ray crystallography to …

Selección y caracterización de germoplasma de melón resistente a A. Aphis gossypii y a los virus que transmite
… existían distintos mecanismos de resistencia (antibiosis y no preferencia) en las entradas de melón TGR-1 55 1, PI-414723 y PI-161375. Sin embargo, las entradas españolas seleccionadas no mostraron resistencia por antibiosis. Como parte de los estudios de caracterización de la resistencia se …

Screening and evaluation of bacteria for the biological control of Botrytis cinerea on Vitis vinifera
… an in vivo assay on wounded grape berries. Antibiosis was evaluated by assessing the effect of the cell-free supernatant on the development of B. cinerea strains. Additionally, polymerase chain reaction (PCR) was used to detect genes related to cyclic lipopeptide (CLP) synthesis, and liquid …

Regulated intramembrane proteolysis in the control of the Bacillus subtilis anti-sigma factor RsiW.
… prokaryotic stress responses, pathogenesis and antibiosis. However, in most cases the molecular basis is not understood. The main objective of this work was to use B. subtilis SigW/ RsiW as a model to investigate the mechanism of RIP in detail. In particular, there are significant differences to …

Genome-guided bioprospecting for novel antibiotic lead compounds.
… was collected from the rhizosphere in which antibiosis occurs naturally. Using starvation stress, sixty-five isolates were recovered from the sample, out of which four were selected based on morphology and designated A13BB, A23BA, A13AA and A23AA. A13BB was identified by 16S rRNA gene …

Identification and preliminary characterization of the 2,5-diphenyloxazole biosynthetic pathway in streptomyces polyantibioticus SPRT
… Streptomyces polyantibioticus SPRT, exhibited antibiosis against Mycobacterium tuberculosis H37RvT (the causative agent of tuberculosis), which prompted interest in its biosynthesis. The antibacterial compound was isolated in a previous study and its structure was determined by X-ray …

Co-existence and niche separation of two subspecies of Photorhabdus temperata associated with Heterorhabditis downesi in a dune grassland
… with a single nematode species (Chapter 2). In antibiosis tests against a range of organisms the P. temperata subsp. cinerea isolates had a greater inhibitory effect than the P. temperata subsp. temperata isolates. Only one pair of isolates, yel1 and pur2, showed any antibiotic activity against …
