Palm trees (Arecaceae) are among the most popular ornamental plants worldwide. Despite extensive research on fungi associated with Arecaceae, diversity and ecological dynamics of affecting palms remain poorly studied, although they have significant impact palm health economic value. Furthermore, while fungal has traditionally focused tropical assemblages, in temperate climates offer a unique opportunity to explore non-native habitats. The present study conducted preliminary assessment ecology potential phytopathogenic foliar lesions various host species Portugal, combining morphological examination, PCR-based genomic fingerprinting, biodiversity data analysis. examination 134 sampled from 100 resulted collection 2064 leaf spotting (PLSF), representing diverse assemblage 320 molecular operational taxonomic units (MOTUs) across 97 genera. overall community composition revealed distinct dominated by Neosetophoma, Alternaria, Phoma, Cladosporium, profusion infrequent rare taxa consistent logseries distribution. Significantly positive co-occurrence (CO) patterns prevalent uncommon suggest synergistic interactions enhancing colonisation, persistence, pathogenicity. structures PLSF contrasted markedly fungi, especially prevalence pleosporalean coelomycetes Didymellaceae Phaeosphaeriaceae, including recently introduced or not previously documented genera Arecaceae. This novel suggests that climatic constraints shape structure communities, resulting distinctive assemblages. In addition, assemblages varied significantly species, temperate-native hosting more diverse, coelomycete-enriched communities. findings highlight as hyperdiverse microhabitats harbouring communities intricate complex interplay climatic, host, factors. With climate change altering environmental conditions, identification thriving inhabiting these becomes crucial for predicting shifts pathogen mitigating future disease outbreaks. Understanding is essential identifying threats developing effective management strategies sustainability plants.

Root Disease Complexes of Arable Crops: Where Do We Stand and Where Should We Go?

Critical Reviews in Plant Sciences, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 29

Published: March 20, 2025

Root diseases are a major global threat to sustainable agricultural production. Complexes of interacting soilborne fungal, oomycete and nematode pathogens involved in causing these that generally termed root disease complexes. These pathogen complexes typically have resilient long-term survival mechanisms, the ability cross-infect multiple crop genera species, wide range spatial dispersal modes. Although, some instances, individual within complex been identified using classical molecular techniques, most cases full remain undefined. At level, it is increasingly obvious different engage unique sets proteins infect hosts successfully. In addition, unpredictable ever-changing nature space time challenges their management. A better understanding whole system dynamics thus prerequisite for effective management, especially under climate change scenarios. Management dependent upon improved detection diagnostic techniques accurately define complement involved, along with an evolution complexes, epidemiology, adaptation across wide-ranging dynamic systems. This review will focus on arable crops, particular emphasis diagnosis, genetic diversity, management options, and, how airborne interact, identify future scope research.
