“…These ecological consequences have been proposed to be associated with various environmental pollutants, such as agrochemicals, heavy metals, and emerging biotoxins [ [4] , [5] , [6] , [7] ]. As the largest agroecosystem and wetland ecosystem on Earth, the paddy ecosystem is a dominant habitat for amphibians [ 8 ]. However, a wide array of phytopathogen-derived biotoxins, such as tropolone (TR) [ 9 ], ustiloxins [ 10 , 11 ], and pyricuol [ 12 ], have been frequently detected in soils and sediments, especially in aquatic compartments [ 13 ].…”

“…Current disease prevention is anchored in existing frameworks, such as Koch's Postulates, and is thus predominantly dependent on chemical fungicide application that is designed to prevent single pathogens in agricultural production [ 87 ]. However, single pathogen‐targeted prevention has gradually fallen short of control efficacy in the field.…”

Single pathogen‐targeted disease management measure has shown drawbacks in field efficacy under the scenario of global change. An in‐depth understanding of plant pathogenesis will provide a promising solution but faces the challenges of the emerging paradigm involving the plant microbiome. While the beneficial impact of the plant microbiome is well characterized, their potential role in facilitating pathological processes has so far remained largely overlooked. To address these unsolved controversies and emerging challenges, we hereby highlight the pathobiome, the disease‐assisting portion hidden in the plant microbiome, in the plant pathogenesis paradigm. We review the detrimental actions mediated by the pathobiome at multiple scales and further discuss how natural and human triggers result in the prevalence of the plant pathobiome, which would probably provide a clue to the mitigation of plant disease epidemics. Collectively, the article would advance the current insight into plant pathogenesis and also pave a new way to cope with the upward trends of plant disease by designing the pathobiome‐targeted measure.

Traditional approaches for studying potential interactions in marine ecosystems often struggle to fully capture all taxa in a community, especially rare species. This issue is particularly challenging in coastal waters with high biodiversity and spatiotemporal dynamics. In this study, we employed environmental DNA (eDNA) metabarcoding, utilizing multiple marker genes, to comprehensively investigate interspecific interactions across various domains in the subtropical coastal waters of Hong Kong. The southern and eastern regions of Hong Kong waters exhibit distinct environmental seasonality, and our investigation focused on comparing the potential interaction networks and the keystone taxa between these two regions. The putative species interaction networks across various groups (i.e., bacteria, protists, and metazoans) were revealed by using weighted correlation network analysis (WGCNA). Our results showed that primary consumers, mainly dinoflagellates and ciliates, were the dominant actors within the interaction networks, although their distributions varied between the two regions. Bacterial taxa from the Pseudomonadota groups primarily constituted saprobes in the southern region, while exhibiting an even distribution in the eastern region. The interaction network in the southern region was larger but less stable compared to the eastern region. This could be attributed to the stronger responses of keystone taxa to environmental variations and the relatively higher number of connectors (e.g., Akashiwo and Protoperidinium within Dinophyceae) in the eastern region. Our findings highlight the versatility of eDNA metabarcoding for studying potential species interactions, providing critical insights into ecosystem structure and stability, and offering suggestions for marine biodiversity conservation.
