“…Some clonal effect was detected for the fungal genus Cladosporium, which generally has a saprotrophic lifestyle but may be present in plant tissues as an endophyte or even a pathogen [61] (Table 4). The capacity for Cladosporium species to act as hyperparasites of poplar leaf rust disease-causing fungi has been suggested [62,63], and the interactions of these fungi in the context of poplar selection for pathogen resistance have been shown [63]. Therefore, as a further task, a wider screening of hybrid aspen clones for Cladosporium occurrence could be performed, combining this knowledge with clone resistance to leaf rust infection [62,63].…”

Hybrid aspen Populus tremula L. × Populus tremuloides Michx. is fast-growing and a potential source of biomass for bioenergy production in Europe. However, knowledge about the phytopathological risks to hybrid aspen clones, particularly about frost crack damage as a possible infection gateway of fungal infections, is scarce. Five clones, represented by 205 trees from three trials in Latvia, were studied; two wood samples (at root collar and 1.3 m height) were obtained from each tree. Wood-inhabiting fungi were isolated and identified by the morphology and sequencing of the ITS region with fungal-specific primers, and fungal communities were compared using PERMANOVA. Fungal communities from trees with stem cracks were richer in species, especially pathogens, and species richness was higher in samples collected at 1.3 m height. Plant pathogens were isolated from 52% of all samples. Soft rot-causing Alternaria and Fusarium were dominant; Alternaria was more common at the height of 1.3 m, while Fusarium was more common at the root collar. White rot fungi were isolated from less than 2% of all samples, indicating a low degree of tree infection in the 15- to 16-year-old plantations. Clonal differences were not significant for fungal communities in general; nevertheless, for the occurrence of the genus Cladosporium, clonal differences were observed. In conclusion, the differences in fungal communities in relation to stem cracks implied only indirect clonal effects on phytopathological risks, emphasizing the resistance to stem cracking as a crucial trait for the sustainability of hybrid aspen plantations.

“…This parasitism consists of three distinct mechanisms involving enzymatic, direct and contact parasitisms. Thus, C. oxysporum protects poplar from rust but has no negative effect on the leaves of the plant itself [276].…”

Poplar (Populus) is a genus of woody plants of great economic value. Due to the growing economic importance of poplar, there is a need to ensure its stable growth by increasing its resistance to pathogens. Genetic engineering can create organisms with improved traits faster than traditional methods, and with the development of CRISPR/Cas-based genome editing systems, scientists have a new highly effective tool for creating valuable genotypes. In this review, we summarize the latest research data on poplar diseases, the biology of their pathogens and how these plants resist pathogens. In the final section, we propose to plant male or mixed poplar populations; consider the genes of the MLO group, transcription factors of the WRKY and MYB families and defensive proteins BbChit1, LJAMP2, MsrA2 and PtDef as the most promising targets for genetic engineering; and also pay attention to the possibility of microbiome engineering.

Mangoes belong to Mangifera (Anacardiaceae), which contains 69 species, but only Mangifera indica is popularly cultivated and commercialized. Mango is one of the most important crops grown in China’s Yunnan Province and significantly contributes to the economic security of these locals. Endophytic fungi have been recognized as beneficial microbes that improve plant growth, productivity, and survivability under environmental stress. Nevertheless, many host plant-related endophytic fungi are yet to be identified, including the mango-related species. During this study, we recognized three different fungal species in the family Chaetomiaceae derived from healthy mango (Mangifera indica) leaves based on morphological examinations coupled with multi-gene phylogenetic analysis (ITS, LSU, rpb2, and tub2). These species are Dichotomopilus funicola (KUNCC23-13347) and Humicola wallefii (KUNCC22-10759, 23-13348), derived from new hosts, and a new species of Arcopilus hongheensis (KUNCC22-10767, 23-13346).
