Many fungi are pathogenic on plants and cause significant damage in agriculture forestry. They also part of the natural ecosystem may play a role regulating plant numbers/density. Morphological identification analysis fungi, while important, is often hampered by scarcity discriminatory taxonomic characters endophytic or inconspicuous nature these fungi. Molecular (DNA sequence) data for have emerged as key information diagnostic classification studies, although non-standard laboratory...
Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. In 2013, Fusarium community voiced near unanimous support for concept of represented clade comprising all agriculturally clinically important species, including F. solani species complex (FSSC). Subsequently, this was challenged in 2015 one research group who proposed dividing genus into seven genera, FSSC described as members...
Fusarium wilt is a serious disease of the date palm Phoenix canariensis , caused by oxysporum f. sp. (Foc). A previous study that characterized and compared genetic diversity Australian Foc population with international strains suggested may have had an independent evolutionary origin. The current species phylogeny populations determined not monophyletic, separating into three supported lineages across two phylogenetic complex. This confirms origin for in Australia. However, analysis...
The Fusarium oxysporum species complex ( FOSC ) causes disease in plants and animals, but is also widely dispersed natural ecosystems without evidence of disease. present study screened a population representing across the Australian continent for putative effector genes pisatin demethylase 1 PDA ), pectate lyase pelD) , secreted gene expression SGE xylem SIX ). pelD were prevalent isolates, was at an intermediate level, whereas detected low levels. Phylogenies these compared to EF ‐1α...
Ascochyta koolunga (Didymellaceae, Pleosporales) was first described in 2009 (as Phoma ) and identified as the causal agent of blight Pisum sativum (field pea) South Australia. Since then A. has not been reported anywhere else world, its origins occurrence on other legume (Fabaceae) species remains unknown. Blight leaf spot diseases Australian native, pasture naturalised legumes were studied to investigate a possible native origin . detected or that had symptoms, any regions southern...
Vanilla stem rot, caused by Fusarium oxysporum f. sp. vanillae (Fov), is the main constraint to increasing vanilla production in major vanilla‐producing countries, including Indonesia. The current study investigated origin of Fov Indonesia using a multigene phylogenetic approach. Nineteen isolates were selected represent Indonesia, Comoros, Mexico and Réunion Island. translation elongation factor 1 alpha gene mitochondrial small subunit ribosomal RNA phylogenies resolved into three distinct...
Fusarium goolgardi, isolated from the grass tree Xanthorrhoea glauca in natural ecosystems of Australia, is closely related to fusaria that produce a subgroup trichothecene (type A) mycotoxins lack carbonyl group at carbon atom 8 (C-8). Mass spectrometric analysis revealed F. goolgardi isolates type A trichothecenes, but exhibited one two chemotypes. Some (50%) produced multiple including 4,15-diacetoxyscirpenol (DAS), neosolaniol (NEO), 8-acetylneosolaniol (Ac-NEO) and T-2 toxin (DAS-NEO-T2...
Abstract Ambrosia beetles have co-evolved symbiotic relationships with an array of fungal partners. Mutualistic partners are often highly successful in vertical transmission between beetle generations. These persisting can alter behaviour, resulting the opportunity to occupy new ecological niches and spread geographically. In Australia, ambrosia not currently considered a significant pest commercial Pinus plantations, where bark Ips grandicollis is known as primary invader stressed trees....
Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a major pest of many agricultural and ornamental crops in tropical subtropical regions causing damages that result important economic losses. Insecticides are commonly used greenhouses or fields to control B. populations leading rapid evolution resistance render treatments inefficient. Therefore, for environmental human health concerns, other approaches must be developed this management. In the present study, we compare, using leaf dip...
Abstract The oomycete genus Phytophthora includes plant pathogens that pose significant threats to agricultural systems, natural ecosystems and urban forests. Urban forests are increasingly recognized for their role in mitigating climate change impacts greening initiatives underway worldwide. However, research suggests the forest is also a reservoir of diversity, acting as bridgeheads introduction these into production ecosystems. source linked anthropogenic factors, with live trade primary...
Early detection of exotic pests is key to a timely response for enabling options eradication and future management. It widely recognised that engaging the public industry in general surveillance significantly increases chance detecting newly arrived pathogens. Once new pest or pathogen detected, Australia has guidelines follow via Emergency Plant Pest Response Deed PLANTPLAN. This paper describes unusual symptoms Pinus radiata production nursery New South Wales, Australia, subsequent...
