This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: results showed that P. truncatrospora in all wood types caused the most decay, followed by L. gilbetsonii and lastly I. hispidus. Sweetgum was the wood type that had more decay followed by red maple, laurel oak and water oak. Live oak was the wood type more resistant to decay in all fungal taxa in this study. Furthermore, an emerging pathogen was identified between 2019 and 2021, mortality, blight symptoms and white mycelium were observed on non- native landscape trees Afrocarpus falcatus, Ligustrum japonicum and native Quercus nigra in Gainesville, Florida and subsequently on numerous native and non-native hardwood and conifer species at scattered locations from the panhandle to central Florida. We identified an unknown basidiomycete based on morphological characteristics and molecular data. Based on our analysis a novel taxon that belong to the Cystostereaceae was identified and a new species is proposed. To determine the pathogenicity of this novel species, a greenhouse experiment was performed in Afrocarpus falcatus, Quercus nigra and Ligustrum japonicum were blight symptoms and white mycelium were present. This study highlights a newly discovered fungal taxon that has a wide host range on both angiosperms and gymnosperms and that appears to be a newly emerging pathogen of concern in the Gulf Coast region.

Available in PDF, EPUB and Kindle. Book excerpt: Fungi are key players in the health, diversity, and productivity of forest ecosystems in Pacific Northwest forests, as mycorrhizal associations, pathogens, decomposers, nontimber resources, and food resources for wildlife. A number of invertebrate species are associated with wood decay fungi, serve as vectors for fungal pathogens, or are fungivorous (consume fungi) and influence rates of wood decay and nutrient mineralization. In Washington and Oregon, 31 wildlife species among 8 families are fungivores, and at least 14 wildlife species disperse fungi. Down wood can provide nurse substrates for seedlings and beneficial mycorrhizal fungi, refuges from pathogenic soil fungi, sources of nutrients for decay fungi, and substrates supporting overall fungal diversity. Presence, density, distribution, and diversity of fungi are influenced by forest stand management practices, forest age class, and effects of fire. Old forests provide for a suite of rare fungi species. Old legacy trees retained during forest harvest can provide some degree of conservation of beneficial and rare fungi. Fungi can be difficult to detect and monitor; surveying for fungi at various times of the year, for multiple (at least 5) years, and by including hypogeous (belowground) samples, can improve detection rates. Studies are needed in the Pacific Northwest to quantify the amount of down wood--number of pieces, sizes, total biomass, percentage of forest floor cover, and other attributes--necessary for maintaining or restoring fungal biodiversity and viable levels of individual fungi species, especially rare species.

Book excerpt: S2Our previous research has focused primarily on ways to identify the wood decay fungi and microbial community. We continue to explore this complex and dynamic community and its interactions through microbial community ecology studies, gene expression interactions and proteomics. However, in order to better understand the mechanisms of fungal decay, we have sequenced the genome of a copper tolerant brown rot fungus, Antrodia radiculosa. To advance our goals, we will be using structural and comparative genomics to identify novel genes and functional genomics and transcriptomics to systematically discover what genes are activated during wood decay under different environmental conditions.S3.

Download or read book Wood Decay Pathology and Studies of Orchard Longevity in California Almond and Prune Orchards written by Andrew (Bob) James Johnson and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood decay fungi are found wherever there is wood. California's Central Valley has more than 4 million acres of perennial tree and vine crops. With the exception of Armillaria, few studies have attempted to describe wood-decay diseases in these fruit and nut crops. Previous studies that have sought to document wood-decay diseases in orchard crops were primarily surveys of fungal diversity across a large number of host species and provided little understanding about their biology and epidemiology. The purpose of our studies were to re-examine wood decay diseases across almond and prune orchards, identify the problematic fungal species and describe the disease phenomena such that control and management strategies can be designed and evaluated. Almond orchards occupy 1.5 million acres in the central valley and are one of the state's most valuable crops. In almond orchards, previous surveys for wood decay fungi identified Ganoderma and Fomitopsis as the most prevalent wood decay genera, both of which are known to cause a root and butt rot. We investigated reports of decay related tree failures in 75 almond orchards in 11 counties throughout California's Central Valley. Seven genera of wood decay fungi were found associated with root and butt failures, the majority were Ganoderma species and a majority of reports were in the southern almond growing region. Ganoderma was identified to the species level using GenBank searches and construction of a maximum likelihood phylogenetic tree using the internal transcribed spacer (ITS) region sequences from Ganoderma isolates obtained from orchards and from non-agricultural hosts. Ganoderma isolates from orchards fell into three clades. Ganoderma adspersum, previously unreported in California, constituted a majority of isolates from orchards and grouped into a clade with GenBank accessions from Europe and Asia. The remaining orchard isolates grouped in either the G. brownii/G. australe complex or the G. polychromum clade, both of which also contained isolates from non-agricultural hosts in California. Koch's postulates confirmed that G. adspersum is capable of causing decay in almond trees and laboratory decay rate comparison trials showed that G. adspersum caused significantly more mass loss in Prunus wood blocks than did other Ganoderma species. Observations indicate that infections begin at or below the soil line and somatic incompatibility trials of isolates from nearby trees indicate spores are the primary inoculum. Prunes have been commercially grown in California for more than a century and prune production and processing are important to local economies, especially in the Sacramento Valley. In recent decades, wood decay has emerged as a significant threat to the industry by reducing orchard longevity. However, little information is available about the incidence and severity of wood decay, therefore effective management and control strategies are lacking. Over the course of three years, we conducted systematic surveys of wood-decay fungi in 35 prune orchards throughout the Sacramento Valley. We determined disease severity in individual trees and the incidence of infection within orchard blocks across multiple age classes. Using these data, we created a model of disease progress. In this work we found the ubiquitous presence of Phellinus heart-rot throughout Sacramento Valley prune orchards, resulting in substantial limb breakage. Infections were associated with pruning wounds and began to appear in orchards as young as 7-years, with 50% or more trees infected by age 15. This study shows that control and management strategies must focus on prevention rather than eradication. In order to understand the impact of a disease that impacts orchard longevity, a clear understanding of orchard lifespan was needed. Almond orchards are generally considered a sound and productive financial investment, driving the continued expansion of the industry. Orchard lifespan is a primary determinant of orchard environmental and economic performance; however, prior estimates of lifespan have typically relied on expert consensus rather than empirical data. We utilized GIS datasets of orchard area and planting date and publicly available historical aerial images to determine average age at orchard removal for the three primary almond production regions of California (Sacramento Valley, San Joaquin Valley, and Tulare Lake Basin). Our analysis indicates that generally accepted expectations for orchard productive lifespan were inaccurate in two of the three production regions. Our statistical analysis has demonstrated that while orchards in the San Joaquin Valley generally conformed with previous assumptions, mean age at removal was significantly lower than expected in both the Sacramento Valley and the Tulare Lake Basin.
