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 evidence-based hypothesis is presented that the stems and branches of Pinus sylvestris injured by lightning strikes are colonized first by Therrya fuckelii and successively by Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella abietina and Cenangium ferruginosum. The concomitant occurrence of these usually pathogenic fungi on injured Pinus trees in Poland signals a potential for their increased significance in Europe during climatic changes.
Praca stara się udowodnić, że strzały i gałęzie sosny zwyczajnej uszkodzonej uderzeniami pioruna kolonizowane są przez Therrya fuckelii, a następnie przez Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella abietina i Cenangium ferruginosum. Sukcesja i wspólne występowanie tych, w większości patogenicznych, grzybów na uszkodzonych sosnach sygnalizuje wzrost ich potencjału i znaczenia w Polsce i Europie. Wynikają one z obserwowanych ostatnio zmian klimatycznych i występowania pogody obfitującej w częste burze i wyładowania atmosferyczne.

Opis:
Effects of 62 isolates (of 41 taxa) of fungi on growth of 1-year-old oak (Quercus robur) seedlings were studied in an inoculation experiment. The fungi were isolated from roots of 80–96-year-old Q. robur that had been subjected to periodic flooding and had symptoms of oak decline. The fungal genera included Alternaria, Aspergillus, Calonectria, Chaetomium, Cladosporium, Clonostachys, Corynespora, Cylindrocarpon, Dicyma, Geotrichum, Ilyonectria, Isaria, Metarhizium, Oidiodendron, Ophiostoma, Pezicula, Phialocephala, Phialophora, Pyrenochaeta, Sporendocladia, Sporothrix, Thelonectria, Trichoderma and Trimmatostroma. Mycelial colonies of fungi growing in potato-dextrose broth were used for soil inoculation. Plant growth was assessed 2 years after inoculation, when the plants were 3 years old. Stem lengths, and dry weights of stems, roots and leaves were measured. Stem growth was inhibited by 31 isolates (50%) and root growth by 12 isolates (19%). Stem growth was stimulated by two isolates (3%) and root growth by 17 isolates (27%). The overall ratio of inhibitors to stimulants was 2.1. The proportion of taxa that inhibited stem growth was 16 times greater than that which promoted stem growth. The proportion of taxa that promoted root growth was only 1.5 times greater than that which inhibited root growth. The structure of the fungal communities in periodically flooded oak forests suggests that they are more likely to inhibit than to promote vigour in oaks.

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.
