Opis:
The health status of 6−16−year−old poplars (mostly Populus robusta) in the sanitary protection zones around Legnica and Głogów copper mills (SW Poland) is described. The health of the poplars was assessed as a frequency of trees with symptoms of stem canker and occurrence of virus diseases on leaves. Fungi were isolated from 24 samples of canker wood (20×20×20 cm each) in five afforested complexes and then identified on the basis of colony morphology and sporulation on PDA and SNA after 40 days of incubation. Cankers occurred on <5−95% of poplar trees. Poplar mosaic virus was observed sporadically in collections of P. robusta, P. balsamifera and P. gerlica. The canker wood was colonized by 20 species of facultative pathogens. Acremonium pteridii, Exophiala sp. and Gibberella baccata were the most common and frequent (in 4−5 complexes). Aureobasidium pullulans, Epicoccum nigrum and Fusarium solani occurred in 3−4 complexes. Alternaria alternata, Cadophora fastigiata, Didymella molleriana, Fusicolla aquaeductuum, Gibberella avenacea, Graphium sp., Leptosphaeria maculans, Nectria inventa, Phoma herbarum, P. minutella, Sarocladium strictum, Trichosporon ovoides and Valsa sordida were less frequent and often occurred only locally. The fungi recorded may serve as indicators of the vitality and health status of trees in industrial zones. The best approach to eliminate the risk of colonization by pathogens is to maintain trees in a state of vigorous growth. Management practices that promote good growth include fertiliza− tion, watering during drought, avoidance of unnecessary wounding of trunk and roots, and using correct pruning procedures.

Opis:
The susceptibility of forest trees to Armillaria butt and root rot is described. The paper characterises the most common Armillaria species and presents the mechanical, physiological and chemical mechanisms of plant resistance against Armillaria. The importance of stress as a cause of increased susceptibility of plants to infection is emphasised. Stress in plants may be caused by drought or an excess of water in the soil, inappropriate temperature, unsuitable soil pH, shortage of oxygen in the ground, wrong nutrition, lack of light, pollution of the soil or air, and the presence of damaging macro−, mezo− or microflora and fauna. Stress decreases the production of cambium in the affected area, the production of resins that limit colonisation, the intensity of photosynthesis, respiration and the transport of nutrients. Stress causes the hydrolysis of carbohydrates necessary for production of energy required for resistance responses, increases accumulation of glucose and other substances used by Armillaria, favours the degradation of phenols that limit colonization, increases susceptibility to other stress factors, and decreases regeneration of the trees.

Opis:
The aim of the studies was to check the usefulness of ITS1/2 rDNA and 18S rDNA regions in the molecular investigation of forest soil microbiota structure. Soil studied, originated from a 1−year−old plantation and a 40−year old stand of Scots pine located in Bierzwnik and Międzychów forest districts located 200 km apart. The hypothesis assumed that both approaches lead to the discovery of abundant microbiota communities with different structures and with rare common species. The environmental DNA was extracted with a Power Soil ® DNA Isolation Kit from two soil samples in each site. The ITS1/2 rDNA was amplified with specific primers ITS1 and ewfitsrev 1, and 18S rDNA with universal primers NS1 and NS2. PCR products were cloned into pGEM−T Easy. Inserts were primarily selected in blue/white screening on a X−gal medium. Representative clones were further selected in two separate RFLP analyses with HhaI and BsuRI restriction enzymes. Representative clones purified and sequenced using the Sanger Method in the DNA Research Centre (Poznań). Each sequence was identified to the lowest taxonomic rank. Ninety to 233 clones with DNA of 5−44 taxa including 3−37 taxa of fungi were obtained from 4 samples of soil. After application of ITS1/2 rDNA and 18S rDNA, the fungal DNA was detected respectively in 89,60−100,00% and 11,77−64,8% clones and the number of fungal species detected was respectively 12−37 and 3−19. Fungi were represented by four orders: Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota. Both primers also amplified also DNA of other organisms (mostly from Animalia and Protista Kingdom) represented by 0−9 taxa. If compared, the application of forest soil microbiota structure with ITS1/2 rDNA and 18S rDNA led to detect a lower abundance of fungi and a bigger abundance of other organisms. Considering the higher number of clones and taxa recognized, the region of ITS1/2 rDNA was more effective in the studies of the soil microbiota structure. The region of 18S rDNA was efficient in local detection of Chytridiomycota and Zygomycota and of rare species of fungi from Ascomycota and Basidiomycota. Despite the deficiency of NCBI database the use of the 18S rDNA region in studies on fungal community the region should be included in molecular studies of fungal diversity. It is concluded that studies on the biodiversity of soil microorganisms need the application of a few independent methods of detection and identification.

Opis:
Fungi in soil perform important services related to nutrient cycling, water dynamics and disease suppression. Along with bacteria, they are important as decomposers in the soil food network. Fungi convert hard−to−digest organic material into forms that other organisms can use. They can immobilize or retain nutrients in the soil. Secondary fungal metabolites have the fungistatic properties and are used in biocontrol processes. The hyphae physically binds soil particles together, creating stable aggregates that help increase water infiltration and soil water retention capacity. Fungi help to increase the accumulation of humic−acid rich organic matter that is resistant to degradation and may stay in the soil for hundreds of year.

Opis:
Two different communities of microorganisms were identified in soils by application of the classical method of fungi isolation (soil dilution, culturing on artificial media, morphotyping) and a molecular method (extraction of the environmental DNA, amplification with universal primers NS1 and NS2, cloning and sequencing of representative clones). No organisms were common to both communities. Apart from rare representatives of the Animalia, communities included single fungus−like Eucarya belonging to the Protista, Class Oomycota, and numerous fungi belonging to Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota orders. In total, 88 species were identified in four soil samples. Fungi were mostly Ascomycota. The classical method was particularly effective in detection of fungi important for creation of phytosanitary conditions of soil, i.e. antagonists (Penicillium, Tolypocladium and Trichoderma) and potential stimulants (dark−pigmented Hormiactis candida, Humicola spp. and Phialophora spp.) of phytopathogens (including the common forest genera Armillaria and Heterobasidion). Application of the classical method allowed the detection of mycorrhizal Ascomycota from the genus Oidiodendron. Application of the molecular method allowed the detection of 13 mycorrhizal Basidiomycota. Although primers NS1 and NS2 were designed from a match with DNA of culturable organisms, they also amplified the DNA of non−culturable organisms. This emphasizes their potential usefulness in studies of the biodiversity of microorganisms in environmental samples. The shortage of reference sequences in the database discourages use of the 18S rDNA region in studies on fungal communities. The studies on the biodiversity of microorganisms need the application of a few independent methods of detection and identification.

Opis:
Awareness of the importance of the presence of deadwood in forest ecosystems has increased in recent decades. Today, deadwood is not only recognized as a key element in carbon sequestration, nutrient supply and water retention, but is also known to be a reservoir of saproxylic species (species associated with the decay of wood on living and dead trees). The amount of deadwood in clear−cut forest is currently higher than 100 years ago. The issue of how much deadwood and of what quality (including size) there should be in order to promote the conservation of saproxylic biodiversity and sustainable forest management is still vivid. Mycological analyses to determine (i) structure of fungal communities in Scots pine wood debris, (ii) sources and reservoirs of fungi, (iii) nutritional preferences of fungi, and (iv) potential rate and dynamics of wood decomposition were carried out on an ‘old' and ‘fresh' wood (stumps, branches and boughs) from Jedwabno Forest District (north−eastern Poland). Fungi from 62 wood samples were isolated on two artificial media (PDA and SNA) and identified according to their morphology. Eleven species of Zygomycota, 79 of Ascomycota and 15 of Basidiomycota were detected. The majority of species (91%) colonized many samples. Only 9% of species colonized single samples only. The most common species, with high rates of colonization, included Acremonium spp., Alternaria sp., Aspergillus spp., Aureobasidium pullulans, Cladosporium spp., Epicoccum nigrum, Lecythophora spp., Mariannaea elegans, Ophiostoma + Sporothrix spp., Penicillium spp., Phialocephala spp., Phialophora spp., Phlebiopsis gigantea, Phoma spp., Sarocladium strictum, Scytalidium lignicola, Sydowia polyspora, Trichoderma spp. (mainly T. harzianum and T. viride) and Umbelopsis spp. A few species occurred only on stumps or only on branches. More species occurred on 'old' wood than on 'fresh' wood. The average level of sample colonization by a single fungal species was higher (non−significantly) on 'old' than on 'fresh' wood, and on branches than on stumps. The results show that deadwood is a habitat for many fungal species that occur in succession. The presence of deadwood in clear−cut forest and in its neighborhood is necessary for the conservation of saproxylic fungal diversity and ecological sustainability of forests.

Opis:
Phytophthora and Pythium species (Oomycota) are known to be serious pathogens of forest trees. Little is known, however, about their presence in Polish oak forests and their role in the oak decline, especially in the flooded areas. The aim of this study was (1) to detect and compare populations of microorganisms from Oomycota and fungi in roots and soil of healthy and declining pedunculate 30−126 years old oak stands, which had been flooded by the Odra River for three months in 1997 and one month in 2010, (2) to demonstrate the relationship between different chemical factors of soil and the occurrence of microorganisms, and (3) to assess the contribution of Oomycota to oak decline. Study was carried out in Wołów Forest District (south−western Poland). Microorganisms were isolated from fine (1−5 mm in diameter) roots and non−rhizosphere soil collected from 0−50 cm horizon. Isolation procedure from roots included surface sterilization and plating the root segments on the nutrient agar. An oak leaf baiting method was used for isolation of Oomycota from soil. Identification of microorganisms was based on morphology and sequencing of the ITS1/2 rDNA. Oomycota was represented by: Globisporangium, Phytophthora and Pythium and fungi mostly by: Aspergillus, Chaetosphaeria, Cylindrocarpon, Mortierella, Mucor, Penicillium, Trichoderma and Umbelopsis. Globisporangium attrantheridium (syn. Pythium attrantheridium) occurred locally and was found in roots of only one flooded oak. This is the first record of this species on oak and in Poland. G. intermedium, P. gibbosa/P. gregata, P. plurivora and Pythium sp. were found in soil of flooded and non−flooded (control) oak stands. The organisms occurred in podzolized brown soils, brown alluvial soils and gley soils that had most nitrogen (21−60 mg/kg), various amounts of calcium (61.1−347.6 mg/100g) and moderate acidity (pH=3.85−4.2). There was often a significant association between exposure to flood and the health status of oak trees assessed by the scale of defoliation. Oomycota seemed to be only moderately associated with increased tree defoliation as a symptom of oak decline.

Opis:
Application of the correct methods of study is essential for a proper description and understanding of natural communities of microorganisms and their relationships. Classical methods used for detection and identification of soil microorganisms resulted in underestimation of the microbiota. It has been claimed that classical methods, based mainly on morphology, led to the identification of only 1% of the soil microbiota, usually species that predominate in culture because of their fast growth and abundant sporulation. Molecular methods allow rapid, accurate, sensitive and cost−effective identification and enumeration of microorganisms. They are designed to replace and/or support classical approaches. This review summarizes some of the current and emerging nucleic acid−based molecular approaches used for detection, discrimination and quantification of microbes in the environment, mostly in soil.

Mixture of the Penicillium adametzii metabolites present in the chloroform extract usually did not inhibit the growth of damping−off fungi, including C. destructans, F. oxysporum. F. sambucinum, F. solani and R. solani, in vitro. Extract from the P. adametzii liquid culture: (i) protected the inoculated pine seedlings from the damping−off only temporarily, (ii) decreased the health of the non−inoculated seedlings, (iii) caused the temporary increases of the fungal population in soil, (iv) changed structure of the soil fungi communities, and (v) caused the continuous increase of Trichoderma, mostly T. aureoviride population. The increase of pine seedlings damping−off was connected with the increase of T. aureoviride population in soil. Natural isolates of P. adametzii cannot be considered as the effective biological factor in the biological control of damping−off.

Opis:
The presence of microorganisms in the substrate is detected with increasing frequency using chemical methods. During the first 9 weeks ergosterol concentration in sterile or not sterile soil inoculated with one of the damping−off fungi reached 966 μg/g, while number of colony forming units (cfu) went up to 247×103 cfu/g. Ergosterol concentration was correlated with the size of the soil fungal community estimated in terms of the number of colony forming units in soil. Pearson's correlation coefficient was 0.700−0.946 for sterile and not sterile soil. Higher content of ergosterol was observed for F. sambucinum var. sambucinum, H. haematococca and T. cucumeris while higher average content of cfu was observed for H. haematococca and T. cucumeris.

Opis:
The abundance and diversity of wood decomposing fungi were investigated by isolating and cultivating filamentous fungi from wood and by detection of fruit bodies of ascomycetous and basidiomycetous fungi. The objective was to study the impact of forest management on fungi in 100-year-old oak and 87-year-old Scots pine forests in Northern Poland. Fungi were found on coarse woody debris of decayed stumps and fallen logs, boughs and branches in each of the three (managed and unmanaged) examined stands. In total, 226 species of Oomycota and fungi were recorded. Oak wood was colonized by one species of Oomycota and 141 species of fungi including Zygomycota (19 species), Ascomycota (103 species) and Basidiomycota (19 species). Scots pine wood was also colonized by one species of Oomycota and 138 species of fungi including Zygomycota (19 species), Ascomycota (90 species) and Basidiomycota (29 species). In the first, second and third stages of decomposition, the oak wood was colonized by 101, 89 and 56 species of fungi respectively and pine wood was colonized by 82, 103 and 47 species respectively. Eighty three of the observed species (37%) occurred on both types of wood, while the other species displayed nutritional preferences. A decrease in the number of species with advancing decay indicates the necessity for a continuous supply of dead wood to the forest ecosystem. This supply would secure the continuity of fauna and flora and guarantee a stable forest development. The nutritional and ecological preferences of many fungal species furthermore indicate the necessity of supplying the forests with wood of different species. In commercially managed forests the results obtained here will aid in: (i) the development of strategies for effective dead wood management in the context of forest productivity and future wood stock growth, as well as (ii) finding a compromise between forest management requirements and environmental protection.
