Available in PDF, EPUB and Kindle. Book excerpt: The symbiotic ectomycorrhizal (ECM) relationship between trees and fungal associates in the Sierra Nevada Foothills of California may influence survival in the harsh Mediterranean climate. Several experiments evaluated the function and occurrence of ECM fungi associated with native trees in California's oak-pine woodlands. Studies focused on identifying fungal hyphae species present near mature trees, and nutrient cycling between hyphae and saplings as well as between paired saplings. To evaluate hyphal length and investigate the identity of ECM hyphae surrounding mature trees, nylon mesh bags filled with sand were buried within the top 10 cm of soil around Quercus douglasii, Q. wislizeni, Pinus sabiniana, or P. ponderosa trees. After one year, hyphae were extracted from the bags and hyphal length was measured by various techniques. Hyphal length measured by microscope images and line intersect method was the most efficient method. Molecular identification of hyphal species revealed Thelephoraceae and Boletaceae were common under both Quercus spp. and P. sabiniana; however, hyphal communities ultimately differed among tree species and overlapped somewhat with reported sporocarp and root tip communities at the same site. Nutrient transfer mechanisms between hyphae and P. ponderosa saplings were investigated by applying Rb and 15N-NH4 to soil in a PVC hyphal chamber buried near the sapling. Nitrogen transfer to the saplings as determined by foliar [delta]15N levels throughout the year exhibited large variations. Greatest Rb transfer occurred within 80 days. The following year, 15N-NH4 was applied again to the chamber and 13C-CO2 was applied to the sapling. Analysis of harvested saplings, soil, and chamber found elevated 15N levels in all components. Carbon (13C) transferred into sapling roots, rhizosphere soil, and hyphal tissues in chamber. Soil surrounding saplings and chambers were not enriched in 13C, which suggested hyphal mediated transfer. Sapling to sapling transfer of foliar applied 15N-NO3− demonstrated high retention in donor needles and stems. Mycorrhizal colonization in receiver plants and 15N concentrations in neighboring forbs were negatively correlated. Uptake of 15N by herbaceous arbuscular mycorrhizal hosts occurred where N accessed was probably from rhizodeposits and hyphal turnover. Grasses and forbs accumulated more 15N than legumes.

Book excerpt: Ectomycorrhizae: Their Ecology and Physiology provides an overview of the state of knowledge and opinion on the physiological ecology of ectomycorrhizae, which may be defined as symbiotic associations between nonpathogenic or weakly pathogenic fungi and living cells of roots. Although the book places considerable emphasis on forestry aspects of mycorrhizal problems, its wide ranging subject matter cuts across the boundaries of a number of traditional plant sciences. The book begins with discussions of the structure, cytology, and morphogenesis of mycorrhizae; their classification; and their distribution in native and man-made forests. It then deals with the growth of ectomycorrhizal fungi around seeds and roots; nutrition uptake; and the role of hormones in mycorrhizal development. The remaining chapters cover the rhizosphere; the role of mycorrhizae in feeder root diseases and the mechanisms for their resistance; and applications of mycorrhizal relations in forest management. This book will be of interest to a wide variety of researchers and teachers, especially agronomists, biochemists, foresters, horticulturists, mycologists, plant pathologists, soil scientists, plant ecologists, plant physiologists, and microbiologists.

This book was released on 2010-11-15 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ectomycorrhizal fungi play multifunctional roles during symbioses with higher plants. They can serve as bioprotectors, biofertilizers, bioremediators and stress indicators. Further, they are the true “mycoindicators” of forest ecosystems, where an enormous diversity of ectomycorrhizal fungi can be found. Some ectomycorrhizal fungi also produce edible sporocarps, i.e., fruiting bodies, which are important for the food industry. Ectomycorrhizal fungi also produce various metal chelating molecules, which are of remarkable biotechnological significance and which also secrete useful secondary metabolites. Molecular approaches are required for the identification and differentiation of fungi forming symbioses with higher plants, while molecular tools are important to understand how genes are expressed during symbiosis with higher plants. Students, researchers and teachers of botany, mycology, microbiology, forestry, and biotechnology will find a valuable source of information in this Soil Biology volume.

Download or read book Mycorrhizal Networks written by Thomas R. Horton and published by Springer. This book was released on 2015-11-16 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last 25 years have seen significant advances in our understanding of the mycorrhizal fungi that colonize most of the world’s plants, and the mycorrhizal networks that form and extend into the soil beyond plant roots. In addition to a thorough review of recent research on mycorrhizal networks, this book provides readers with alternative perspectives. The book is organized into three sections: Network Structure, Nutrient Dynamics, and the Mutualism-Parasitism Continuum. Chapter 1 addresses the specificity of ectomycorrhizal symbionts and its role in plant communities, and provides an updated list of terms and definitions. Chapter 2 explores interactions between symbionts in mycorrhizal fungi networks, as well as interactions between fungal individuals. The second section of the book begins with the examination in Chapter 3 of extramatrical mycelium (mycelia beyond the root tips) in ectomycorrhizal fungi, focused on carbon and nitrogen. Chapter 4 reviews the influence of mycorrhizal networks on outcomes of plant competition in arbuscular mycorrhizal plant communities. Chapter 5 discusses nutrient movement between plants through networks with a focus on the magnitude, fate and importance of mycorrhiza-derived nutrients in ectomycorrhizal plants. Section 3 opens with a review of research on the role of ectomycorrhizal networks on seedling establishment in a primary successional habitat, in Chapter 6. The focus of Chapter 7 is on facilitation and antagonism in arbuscular mycorrhizal networks. Chapter 8 explores the unique networking dynamic of Alnus, which differs from most ectomycorrhizal plant hosts in forming isolated networks with little direct connections to networks of other host species in a forest. Chapter 9 argues that most experiments have not adequately tested the role of mycorrhizal networks on plant community dynamics, and suggests more tests to rule out alternative hypotheses to carbon movement between plants, especially those that include experimental manipulations of the mycorrhizal networks. Plant ecologists have accumulated a rich body of knowledge regarding nutrient acquisition by plants. The editor proposes that research indicating that mycorrhizal fungi compete for nutrients, which are then delivered to multiple hosts through mycorrhizal networks, represents an important new paradigm for plant ecologists.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of the abundance and rapidity of ectomycorrhiza and root tip formation on conifer seedling survival and growth was investigated on disturbed forest sites in southwest Oregon and northern California. Experiments were conducted over a range of community types and environmental conditions. A range of sources of transfer soil were evaluated to offset disturbance-related reductions in ectomycorrhiza formation. We established different levels of native mycorrhizae by growing seedlings in soils from either (a) a poorly restocked clearcut in southwest Oregon, or (b) forest adjacent to the clearcut. At the time of outplanting, only 4% of root tips were mycorrhizal on seedling grown in clearcut soils, while 42% were mycorrhizal on seedlings grown in forest soils. There were significant differences in growth following outplanting. Seedlings greenhouse-grown in clearcut soil averaged nearly 44% less basal area growth and 14% less height growth than those greenhouse-grown in forest soil. Survival and mycorrhiza formation differed among Douglas-fir seedlings planted in three adjacent community types-whiteleaf manzanita, annual grass meadow, and an open stand of Oregon white oak. Second-year survival averaged 92%, 43%, and 12% for seedlings planted on the manzanita, meadow, and oak sites, respectively. Growth differences generally paralleled survival differences. Growth of seedlings on the manzanita site was substantially increased by the addition of unpasteurized machone soil, nearly tripling the number of mycorrhizal root tips formed. Mycorrhiza formation and conifer seedling performance was examined over a range of sources of transfer soils and environmental conditions on three old and unsucessfully reforested clearcuts. At Cedar Camp, a high elevation (1720m) southerly slope with sandy soils, transfer of plantation soils increased 1 st-year Douglas-fir seedling survival 50%, doubled mycorrhiza formation and tripled seedling basal area growth. Soil from mature forest did not improve growth and survival. Less dramatic effects owing to soil transfer were evident on the other sites, which were lower in elevation had greater water holding capacity, and where woody shrubs had apparently preserved mycorrhizal fungi. In another study, seedlings receiving plantation soil transfer at Cedar Camp had 62% more root tips than controls six weeks after ouplanting; however differences were no longer statistically significant 15 weeks after planting. Seedlings receiving transferred soil had the most mycorrhizal colonization. Of seedlings receiving transfer soil, 36.6% survived the first growing season, compared to 11.3% of control seedlings.
