Special Issue Information

Dear Colleagues,

Forest ecosystems throughout the world are increasingly affected by changing climate, international trade and transport systems. Growing global trade has facilitated the introduction of numerous new tree pathogens into new regions.  The focus in a lot of forest research is on modern mechanisms for prevention and management of potential invasions of forest pathogens as well as mitigating the impact of invasive pathogens within forest ecosystems.

Less knowledge is available on the biological and chemical control of invasive pathogens. The prevention and control of new invasions is a promising tool to improve forest health in the face of increased climate warming. The emergence of a new invasive forest pathogen appears to demand resources for developing countermeasures, such as breeding resistance programs, development of fungicide, and biocontrol agents. Therefore, there is an urgent need to introduce and synthesize the information that illustrates the impacts of invasions of tree pathogens, their biology, forest management, control measures and their interactions, as well as methods to predict, assess and mitigate these impacts.

This Special Issue welcomes studies that consider the recent advances in the development of different measures to prevent the entry and expansion of invasive forest pathogens including their biology, monitoring, epidemiology, ecology, diagnostics, and disease management and control. Thus, this Special Issue promotes the dissemination of knowledge in forest protection for the preservation of diversity and resilience of forest ecosystems. Studies conducted in forests and laboratories, as well as theoretical approaches and literature reviews, are of interest. We encourage studies from broad research topics related to invasive forest pathogens.

Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Basal stem rot (BSR) caused by a wood degrading fungus, Ganoderma boninense, is the major constraint in palm oil production. It degrades the wood components and causes palms to collapse, leading to heavy losses. Inefficacy in controlling this disease could be caused by the lack of understanding in how the pathogen establishes itself on the host concerning wood decay stages. This study aimed to understand and determine the role of benzoic acid on the suppression of G. boninense and production of ligninolytic enzymes responsible for wood decay. Further, the alteration in wood component structure due to G. boninense infection and its prevention were studied. Benzoic acid treatment resulted in more than 80% of inhibition in G. boninense growth. SEM and HR-TEM analysis confirmed the antifungal activity of benzoic acid by disruption of mycelial morphology and cellular ultrastructure. Moreover, the membrane permeability assay recorded enhanced cell mortality in benzoic acid treated mycelium. The degradation of oil palm woodblock caused 58.86 % wood dry weight loss at day 120. In contrast, reduction in dry weight loss (58.82%) was recorded in woodblock treated with concentrations of benzoic acid of 5 mM and above. It is concluded that the use of benzoic acid could inhibit or delay pathogen establishment in oil palm wood, leading to the sustainable management of BSR disease. Further, glasshouse and field trials are required to prove the consistency in current findings which may contribute to reduced land expansion to create new disease-free land for oil palm planting.

Bleeding cankers on horse chestnut trees (Aesculushippocastanum and Aesculus × carnea), caused by Pseudomonassyringae pv. aesculi, have been reported across Europe. In the present study, we show the successful detection of P. syringae pv. aesculi on symptomatic horse chestnut trees in Switzerland using quantitative PCR (qPCR). However, P. syringae pv. aesculi was also detected by qPCR on trees from which no isolate was obtained through cultivation. Reduced isolation success and low copy numbers of the target gene were correlated with the increasing age of symptomatic horse chestnut trees. The potential of detecting non-viable P. syringae pv. aesculi by qPCR was evaluated using an inoculation experiment with dead bacteria and detection by qPCR and cultivation. The detectability of DNA from P. syringae pv. aesculi cells dropped by 34.5% one day after inoculation and then decreased only slightly until the end of the experiment (22 days after inoculation). In contrast, no bacterial growth was observed at any time point after the inactivation of the bacteria. To protect horse chestnut trees, evaluating the viability and actual infection stage of the bacterium may play an important role. Full article

Chestnut blight, a disease that has spread rampantly among American (Castanea dentata (Marsh.) Borkh.) and European chestnut (C. sativa Mill.) trees, results from infection by the fungal pathogen Cryphonectria parasitica (Murrill) M.E. Barr (C. parasitica). This fungus was introduced in the early 1900s and has almost functionally eliminated chestnut trees from the North American landscape. In 2017, we collected chestnut blight samples from two sites (Site B, (Fulton Co., IN) and Site C (Marshall Co., IN)). At the Fulton County planting, Site B, cankers had formed, healed over, and the trees were healthy. However, at the second site in Marshall County, (Site C), cankers continued to propagate until all of the chestnut trees had died back to the ground. Research evidence worldwide has indicated that these visual clues likely result from the presence of a hypovirus. Upon closer inspection and the subsequent isolation and reproduction of spores, no hypovirus has been identified from either site. Here, we present a curious coincidence where one site has completely succumbed to the disease, while the other has been able to spring back to health. Full article
