- Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineage-specific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae, Botryosphaeria, Botrytis, Choanephora, Colletotrichum, Curvularia, Diaporthe, Diplodia, Dothiorella, Fusarium, Gilbertella, Lasiodiplodia, Mucor, Neofusicoccum, Pestalotiopsis, Phyllosticta, Phytophthora, Puccinia, Pyrenophora, Pythium, Rhizopus, Stagonosporopsis, Ustilago and Verticillium are dealt with in this paper.

- Recycling of livestock manure in agroecosystems has been shown to enhance the sustainability of food production and reduce adverse environmental consequences from intensive crop-livestock systems. However, the effect of manure application on the associations between soil quality and ecosystem multifunctionality still remains poorly understood. Hereby, we used a five-year field experiment to investigate the effect of mineral and manure fertilization on soil quality, enzymatic stoichiometry, and ecosystem multifunctionality for both topsoil and subsoil (i.e. 0-20 cm and 20–40 cm). Manure alone and combined with mineral fertilization increased soil quality index by 49.5 and 70.1% in the topsoil, and by 67.5% and 26.6% in subsoil compared to no fertilization. Moreover, the manure application increased the C, N, and P acquisition enzyme activities, especially those for C and P cycling. Fertilization regimes affect enzymatic stoichiometry in subsoil rather than topsoil. Manure application increased soil ecosystem multifunctionality in both top and subsoil by 2.1 and 0.4 times, respectively. Interestingly, the soil quality was positively correlated with ecosystem multifunctionality regardless of fertilization regimes. Furthermore, random forest analysis showed that soil organic C and N content, available P, and microbial biomass were the main drivers of soil ecosystem multifunctionality. Conversely, mineral fertilization did not affect soil quality and enzyme activity in both soil layers, and thus did not change soil ecosystem multifunctionality. In conclusion, manure application fosters soil quality and has the potential to improve the soil multifunctionality, thereby providing an effective way to sustainable soil management and cleaner crop production.

- Poplar wood was modified by a combination of thermo-mechanical densification (TMD) and heat treatment (HT) process at five temperatures ranging from 170 to 210°C. A new two-step conditioning method (CM) is suggested, in the course of which the modified wood is submitted to 50°C/99% RH→25°C/65% RH, where RH means relative humidity in the climate chamber. The traditional one-step CM (25°C/65% RH) served as reference. The effects of conditioning history on hardness were observed and analyzed along with the change of dimensional stability. The hardness of the modified wood was lower in the case of the proposed CM due to more set-recovery release, but the extent of that decreased with the HT temperature. For a good hardness, HT200°C should be selected with the proposed CM, which is different from the optimization output of 180°C obtained from the traditional CM. In conclusion, a specific assessment method for the performance characterization of this type of modified wood would be beneficial for the combined TMD and HT processes.
