Cereal production is vital for food security and economic growth, but insect infestations can significantly reduce crop yields quality, leading to substantial losses. Recent pest management strategies in cereal crops have incorporated innovative techniques, such as utilizing mutualistic plant-microbe interactions that trigger molecular defense mechanisms against pests. Entomopathogenic fungi, particularly Beauveria Metarhizium (Hypocreales), are naturally found soil infect a wide range of arthropod These fungi also colonize plants rhizosphere inhabitants endophytes, offering multiple benefits, including enhanced growth resistance. As these promote plant biomass herbivore development, consumption, oviposition, survival the field.

Abstract Metarhizium fungi are pathogens of arthropods, with several early‐diverged species infecting lizards or mushrooms. Most also beneficial plant symbionts, and they mainly colonize rhizosphere rhizoplane some strains colonizing leaves stems. The development association commence either by the attachment spores to roots colonization. Rhizosphere hyphae further attracted nutrient‐rich root exudates, facilitating Both undifferentiated differentiated (characterized appressorial formation) can penetrate between epidermal cells, sporadical Plant‐derived reactive oxygen play a crucial role in limiting cell colonization . utilizes plant‐derived sugars fatty acids for growth while transferring insect‐derived nitrogen plants.

Melanogenesis and melanin deposition are processes essential for the effective immune response of insects to various invaders. Phenoloxidase (PO), produced in specialized cells as an inactive precursor prophenoloxidase (proPO), is key enzyme formation. The activated via limited proteolysis by a dedicated serine proteinase, which final element cascade proteinases (SPs) that make up PO system. provides different cytotoxic molecules active fighting infections, well melanin, important sequestration However, since reactive compounds generated during melanization also pose threat host cells, strict control system necessary self-protection.

Metarhizium fungi, essential for ecosystem function and commonly utilised in pest control, often occupy ecological niches contaminated by toxic compounds of both anthropogenic microbiological origin. The present study reveals the potential anisopliae biodegradation Fusarium mycotoxin zearalenone (ZEN), a common contaminant crops that poses significant threat to human animal health due its oestrogenic toxicity. A key aspect pathway described is degradation ZEN cleaving lactone bond, which results reduction toxicity, highlighting fungus’s bioremediation potential. Furthermore, this provides first evidence subsequent metabolites through progressive shortening aliphatic chain, primarily via alternating oxidation demethylation, ultimately yielding trihydroxybenzene. Significantly, bond cleavage occurred not only itself but also reduced forms, zearalanols, formed initial zearalenols. Elevated mRNA levels cytochrome P450 (CYP450) monooxygenases M. exposed indicate their involvement mechanisms. Intriguingly, inhibition CYP450 activity resulted substantial shift quantitative ratio α- β-epimers zearalenols zearalanols. observed alteration towards β-form production likely stems from other CYP450-dependent reactions, indirectly influencing pathways—a particularly noteworthy finding. These insights are crucial developing strategies utilise ZEN-contaminated areas.
