The role of fungal chitinases in the tripartite interactions among insects, plants and entomopathogenic fungi.
Review in Pest management science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundChitinases are ubiquitous hydrolytic enzymes in fungi that specifically degrade chitin, a major structural component of insect exoskeletons and fungal cell walls. Increasing evidence indicates that chitinases play multifaceted roles not only in entomopathogenic fungal infection, but also in plant immune modulation and cross-kingdom interactions. However, their integrative functions within the insect-fungus-plant tripartite system remain insufficiently characterized. This review aims to systematically elucidate the molecular mechanisms and ecological functions of fungal chitinases across multitrophic interactions.
resultsAccumulated studies demonstrate that: Chitinases act as critical virulence factors by facilitating fungal adhesion, cuticle degradation, and host penetration during insect infection; In plant-microbe interactions, chitinases contribute to microbial colonization while simultaneously generating chitin-derived oligomers that function as elicitors to activate plant innate immunity; Within the insect-fungus-plant tripartite system, chitinases mediate resource turnover and signal exchange, thereby shaping complex ecological networks and influencing multilevel biological interactions.
conclusionChitinases serve as pivotal molecular hubs linking pathogenicity, symbiosis and ecological regulation across kingdoms. A comprehensive understanding of their multifunctional roles provides critical insights into cross-kingdom interaction mechanisms, and offers promising avenues for advancing biological control strategies, crop resistance improvement and microbial resource exploitation. © 2026 Society of Chemical Industry.
