Lichens assemble in three parts Lichen growth forms cannot be recapitulated the laboratory by culturing plant and fungal partners together. Spribille et al. have discovered that classical binary view of lichens is too simple. Instead, North American beard-like are constituted not two but symbiotic partners: an ascomycetous fungus, a photosynthetic alga, and, unexpectedly, basidiomycetous yeast. The yeast cells form characteristic cortex lichen thallus may important for its shape. yeasts...
Novel species of fungi described in this study include those from various countries as follows: Australia : Banksiophoma australiensis (incl. gen. nov.) on Banksia coccinea , Davidiellomyces Cyperaceae Didymocyrtis banksiae sessilis var . cygnorum Disculoides calophyllae Corymbia calophylla Harknessia banksiae-repens repens banksiigena communis Podocarpus sp., platyphyllae Eucalyptus platyphylla Myrtacremonium eucalypti globulus Myrtapenidiella balenae eucalyptigena pleurocarpae pleurocarpa...
Abstract After the detection of myrtle rust pathogen, Austropuccinia psidii, in New Zealand, a biosecurity response was initiated, including wide-spread surveillance programme. Through an intensive public awareness initiative, general highly engaged reporting infections and added significant value to surveys by first detections from most areas that are now known be infected. During year response, psidii found were predicted at high infection risk previous modelling studies. Significant...
In January and March 2019, an inspection of 11 commercial 'Hass' avocado orchards in mid-North Tauranga (New Zealand) was conducted by NZ Avocado Growers Association Inc. (NZAGA) the samples were sent to Plant Diagnostics Limited for investigation a newly observed fruit staining symptom termed "tannin stain". Fruit symptoms consisted areas minute small spots which coalesced into tear associated with water movement over fruit's surface (Supplementary Fig. 1). Up seven trees per orchard...
Among fungi isolated from healthy root mycobiomes of Populus, we discovered a new endorrhizal fungal species belonging to the rust lineage Pucciniomycotina, described here as Atractiella rhizophila. We characterized this by transmission electron microscopy (TEM), phylogenetic analysis, and plant bioassay experiments. Phylogenetic sequence analysis isolates available environmental reference sequences indicates that species, A. rhizophila, has broad geographic host range. rhizophila appears be...
Our understanding of the systematics red yeasts has greatly improved with availability sequence data and it is now clear that majority these fungi belong to three different classes Pucciniomycotina (Basidiomycota): Agaricostilbomycetes, Cystobasidiomycetes, Microbotryomycetes. Despite improvements in phylogenetic placement, taxonomy long been need revision still not entirely resolved, partly due missing taxa. In present study, we culture-based environmental yeast isolation, revealing several...
Apple leaf blotch has been observed in Nelson and Hawke's Bay regions of New Zealand over recent years. Fungi from the genus Alternaria were consistently obtained symptomatic material, morphological molecular analysis determined that these isolates belong to arborescens complex. Pathogenicity tests carried out determine if fungi causal agents symptoms. Testing was conducted using both orchard glasshouse grown apple leaves, but symptoms only occurred on young leaves some inoculated leaves....
Abstract Red yeasts, primarily species of Rhodotorula , Sporobolomyces and other genera Pucciniomycotina, are traditionally considered proficient systems for lipid terpene production, only recently have also gained consideration the production a wider range molecules biotechnological potential. Improvements transgene delivery protocols regulated gene expression been proposed, but dearth information on compositional and/or structural features genes has prevented sequence optimization efforts...
Early diverging taxa of Ascomycota and Basidiomycota share similarities in subcellular characters the spindle pole body (SPB), nuclear division, septal pore apparatus, but our understanding character evolution is incomplete because limited number structural studies within earliest subphyla Dikarya, Taphrinomycotina Pucciniomycotina. Two species Helicogloea (Atractiellomycetes) were analyzed for these provide data on SPB division an additional class A detailed analysis apparatus permits...
The genus Ceratocystis contains several significant plant pathogens, causing wilt and canker disease on a wide range of species. There are >40 known species Ceratocystis, some which becoming increasingly important in agricultural or natural ecosystems. diagnostic procedures for most rely time-consuming labor-intensive culturing approaches. To provide more time-efficient sensitive molecular tools generic TaqMan real-time PCR assay was developed using the ITS gene. This novel two-probe...
Monilinia vaccinii-corymbosi (Mvc) is an important fungal pathogen of blueberry, causing mummy berry disease. While the symptoms advanced stages disease can be obvious, diagnosing its early challenging. To facilitate fast and sensitive screening asymptomatic or latently infected plant material for Mvc, we developed a specific TaqMan real-time PCR assay targeting internal transcribed spacer (ITS) region. The was shown to Mvc did not cross react with any other tested species blueberry...
The Mycology and Bacteriology team of the Ministry for Primary Industries’ Plant Health Environment Laboratory is responsible identification verification all suspected exotic, new, emerging pathogens affecting plants environment in New Zealand. We work an applied diagnostic where results can have significant implications biosecurity. Sample submissions often result detection new to Zealand fungi bacteria on which information fungal bacterial associations generally sparse. complexity testing...
Abstract Diaporthe vaccinii is a fungal pathogen of concern to Vaccinium species, responsible for twig blight disease. This fungus may survive in woody tissues without displaying symptoms, which makes the diagnostics more challenging. To provide rapid and efficient diagnostic tool D. , new specific TaqMan real‐time PCR assay was developed using translation elongation factor 1 gene region. The did not cross‐react with any other tested pathogens. sensitivity found be pg DNA water or host DNA,...
During the inspection of imported sweet corn (Zea mays), a specimen with dry rot symptoms was detected by Ministry for Primary Industries quarantine officers. A sample sent to MPI Plant Health and Environment Laboratory diagnostics, initial examination found layer yeast cells on surface symptomatic tissue. The fungus cultured identified based DNA sequences as Ustilago maydis. While corn-smut pathogen U. maydis is well known cause tumour like galls kernels, it less recognised fact that this...
A project aiming to enhance biosecurity and market access in the Pacific was launched by NZ Aid 2016. The intends benefit economies of New Zealand’s neighbours improving their systems which, turn, would help protect borders. Under current project, MPI’s Plant Health Environment Laboratory (PHEL) is accountable for delivering insect pest disease diagnostic training developing tools. PHEL Mycology Bacteriology team has delivered a number plant pathology sessions Zealand, Cook Islands Fiji....
