Topical Collection Information

Dear Colleagues,

The widespread presence of plant pathogenic fungi poses a formidable challenge to agricultural and forest ecosystems, and requires concerted research efforts to effectively understand and counter the dynamic landscape of fungal infections. The advent of molecular techniques, such as DNA sequencing and genomics, has introduced a new era of rapid diagnosis for plant pathogenic fungi. In parallel, there has been a growing focus on cultivating sustainable and environmentally friendly strategies to mitigate the impact of these fungi, including advancements in new eco-friendly formulations. Innovative biological control approaches, such as bio-pesticides, beneficial microbes, secondary metabolites of microorganisms, plant extracts, and plant-mediated defences, are considered promising alternatives to conventional chemical interventions.

This Topical Collection is devoted to studying the efficacy of biocontrol agents and their metabolites against fungal pathogens, as well as applying molecular techniques for the identification of fungi associated with agricultural and forest plants. Additionally, it focuses on the development of new environmentally friendly and low-impact formulations, also aiming to address the challenges inherent in species identification—a key aspect of disease management.

Objectives:

To explore recent advances in molecular diagnostics, including genomics and diagnostic tools.

To present sustainable and ecological strategies for the management of plant pathogenic fungi through innovative biological control approaches or novel eco-formulates with low environmental impact.

To explore the integration of diagnostic tools with biological control measures to enhance overall disease management.

An investigation into oomycete diversity in rice paddies of Fars Province in Iran led to the identification of two new Pythium sensu lato (s.l.) species as Globisporangium izadpanahii sp. nov. and Pythium banihashemianum sp. nov. The identification was based on morphological and physiological features as well as on the phylogenetic analysis of nuclear (ITS and βtub) and mitochondrial (cox1 and cox2) loci using Bayesian inference and Maximum Likelihood. The present paper formally describes these two new species and defines their phylogenetic relationships with other congeneric species. According to multiple gene genealogy analysis, G. izadpanahii sp. nov. was grouped with other species of Globisporangium (formerly, clade G of Pythium s.l.) and was closely related to both G. nagaii and the recently described G. coniferarum. The second species, designated P. banihashemianum sp. nov., was grouped with other species of Pythium sensu stricto (formerly, clade B of Pythium s.l.) and, according to the phylogenetic analysis, shared an ancestor with P. plurisporium. The production of globose hyphal swellings was a major characteristic of G. izadpanahii sp. nov., which did not produce vesicles and zoospores. In pathogenicity tests on rice seedlings, P. banihashemianum sp. nov. isolates were highly pathogenic and caused severe root and crown rot, while G. izadpanahii sp. nov. isolates were not pathogenic.

The greater yam (Dioscorea alata), a widely cultivated and nutritious food crop, suffers from widespread yield reduction due to anthracnose caused by Colletotrichum gloeosporioides. Latent infection often occurs before anthracnose phenotypes can be detected, making early prevention difficult and causing significant harm to agricultural production. Through comparative genomic analysis of 60 genomes of 38 species from the Colletotrichum genus, this study identified 17 orthologous gene groups (orthogroups) that were shared by all investigated C. gloeosporioides strains but absent from all other Colletotrichum species. Four of the 17 C. gloeosporioides-specific orthogroups were used as molecular markers for PCR primer designation and C. gloeosporioides detection. All of them can specifically detect C. gloeosporioides out of microbes within and beyond the Colletotrichum genus with different sensitivities. To establish a rapid, portable, and operable anthracnose diagnostic method suitable for field use, specific recombinase polymerase amplification (RPA) primer probe combinations were designed, and a lateral flow (LF)-RPA detection kit for C. gloeosporioides was developed, with the sensitivity reaching the picogram (pg) level. In conclusion, this study identified C. gloeosporioides-specific molecular markers and developed an efficient method for C. gloeosporioides detection, which can be applied to the prevention and control of yam anthracnose as well as anthracnose caused by C. gloeosporioides in other crops. The strategy adopted by this study also serves as a reference for the identification of molecular markers and diagnosis of other plant pathogens. Full article
