Chlorinated phenolic sesquiterpenoids from the Arctic fungus Nectria sp. B-13

Biochemical Systematics and Ecology, 2015
Abstract Seven chlorinated phenolic sesquiterpenoids, together with one prenylated 2-pyridyl ketone alkaloid (9) and two monophenols (10 and 11), were isolated from the fungus Nectria sp. B-13 obtained from an Arctic soil sample. Their chemical structures were elucidated using a combination of spectroscopic data (ESI-MS, 1H, and 13C NMR) and ...

Synthesis and characterization of synthetic analogs of cinnacidin, a novel phytotoxin from Nectria sp.

Pest Management Science, 2008
AbstractBACKGROUND: The novel natural product cinnacidin was isolated from a fungal fermentation extract of Nectria sp. DA060097. The compound was found to contain a cyclopentalenone ring system with an isoleucine subunit linked through an amide bond. Initial biological characterization of cinnacidin suggested promising herbicidal activity.RESULTS: Two

Genetic analysis of variation of pathogenicity in Nectria haematococca (Fusarium solani) on Cucurbita sp.

Mycological Research, 1994
Pathogenicity phenotypes for over 30 isolates of Fusarium solani, from Cucurbita sp., were measured as lesion sizes on both unwounded and wounded seedling hypocotyls and on fruit mesocarp tissue. These tests detected different capacities in both the pre-and post-penetration phases of infection. The isolates were grouped, based on their mating behaviour,

Two new monoterpenoid α-pyrones from a fungusNectriasp. HLS206 associated with the marine spongeGelliodes carnosa

Journal of Asian Natural Products Research, 2015
Two new monoterpenoid α-pyrones, named nectriapyrones C and D (1 and 2), along with a known α-pyrone (nectriapyrone, 3) were isolated from a marine-derived fungus Nectria sp. HLS206 associated with the marine sponge Gelliodes carnosa collected from the South China Sea. Their structures were determined on the basis of 1D NMR, 2D NMR, HR-ESI-MS methods.

Nectria tuberculariformis, Nectriella muelleri, Nectriella sp., and Hyponectria sceptri: low-temperature tolerant, alpine–boreal fungal antagonists

Canadian Journal of Botany, 1984
The ascomycetes Nectria tuberculariformis, Nectriella muelleri sp. nov., Nectriella sp., and Hyponectria sceptri comb. nov. were collected in alpine–boreal habitats. They were low temperature tolerant, growing at 0 °C and poorly or not at all at temperatures above 18 °C. Optimum temperature for spore germination and growth was 10–15 °C.

Cloning and expression analysis of NhL1, a gene encoding an extracellular lipase from the fungal pea pathogen Nectria haematococca MP VI (Fusarium solani f. sp. pisi) that is expressed in planta

Molecular Genetics and Genomics, 2001
The filamentous fungus Nectria haematococca (anamorph Fusarium solani f. sp. pisi) resides in soil, and attacks pea seedlings in the area of the underground epicotyl and upper tap root, causing foot rot disease. We detected lipase activity during in vitro growth of N. haematococca.

Cloning of a New Pectate Lyase GenepelCfromFusarium solanif. sp.pisi(Nectria haematococca,Mating Type VI) and Characterization of the Gene Product Expressed inPichia pastoris

Archives of Biochemistry and Biophysics, 1995
Antibodies prepared against a pectate lyase (PLA) produced by a phytopathogenic fungus Fusarium solani f. sp. pisi (Nectria haematococca, mating type VI) were previously found to protect the host against infection. The cDNA and gene (pelA) for PLA were cloned and sequenced.

Identification of a NovelpelDGene Expressed Uniquely in Planta byFusarium solanif. sp.pisi(Nectria haematococca,Mating Type VI) and Characterization of Its Protein Product as an Endo-Pectate Lyase

Archives of Biochemistry and Biophysics, 1996
Antibodies prepared against a pectin-inducible pectate lyase (PLA) produced by a phytopathogenic fungus Fusarium solani f. sp. pisi (Nectria haematococca, mating type VI) were previously found to protect the host from infection. The gene (pelA) and two of its homologs were cloned and sequenced.

Role of perithecia as an inoculum source for stem rot type of pepper root rot caused by Fusarium solani f. sp. piperis (teleomorph: Nectria haematococca f. sp. piperis)

Journal of General Plant Pathology, 2010
Pepper (Piper nigrum L.) root rot caused by Fusarium solani f. sp. piperis (FSP; teleomorph: Nectria haematococca f. sp. piperis) includes two symptom types called root rot (RR) type and stem rot (SR) type. In this study, the temporal and spatial associations between perithecial formation of FSP and development of SR were investigated in naturally ...
