Abstract Trees form symbioses with ectomycorrhizal (ECM) fungi, maintained in part through mutual benefit to both organisms. Our understanding of the signaling events leading successful interaction between two partners requires further study. This is especially true for role volatile signals produced by ECM fungi. Terpenoids are a predominant class volatiles While several genomes enriched enzymes responsible production these (i.e., terpene synthases (TPSs)) when compared other we have limited biochemical products associated each enzyme and physiological impact specific terpenes on plant growth. Using combination phylogenetic analyses, RNA sequencing, functional characterization five TPSs from distantly related fungi ( Laccaria bicolor Pisolithus microcarpus ), investigated secondary metabolites during establishment symbiosis.

The family exhibits diverse chemical profile of essential oils serves as valuable resource due ecological interactions, adaptability, dispersal capacity. has been extensively studied terpenoids. Genetic studies have focused on foliar terpene yield in species from Eucalypteae Melaleucaceae tribes. To understand evolutionary trends guava breeding, this study predicted synthase genes (TPS) different cultivars. Through analysis, 43 full-length TPS were identified, approximately 77% them exhibited relative expression at least one five investigated plant tissues (root, leaf, bud, flower, fruit) two We identified intra-species variation single nucleotide polymorphisms (SNPs) twelve genes, resulting clustering 62 genotypes according their oil chemotypes. high concentration sesquiterpenes supported by higher number TPS-a expression. expansion sub-families P. occurred after other rosids species.

The current study investigated the impact of nutmeg essential oil (NEO) and tea tree (TTEO) on preservation raw chicken fillets during nine days refrigerated storage study. primary aim was to explore antioxidant antimicrobial properties these oils (EOs) assess their ability extend shelf life poultry meat. Gas chromatography–mass spectrometry (GC-MS) utilized identify chemical compositions NEO TTEO, revealing presence compounds like myristicin terpenoids, known for activities. Antioxidant were evaluated using DPPH ABTS radical scavenging assays, where both exhibited potent free abilities, with showing higher efficacy than TTEO. EOs showed potential, exhibiting significant antibacterial activities against tested Gram-positive Gram-negative pathogens, such as Staphylococcus aureus Escherichia coli, respectively. Raw treated either or TTEO at 1% analyzed physico-chemical, microbiological, sensory attributes. Results demonstrated that NEO- TTEO-treated samples maintained better microbiological qualities, lower total viable counts enhanced attributes, color odor, compared control samples. Furthermore, effectively delayed spoilage, extending by up seven days. This concludes test’s can be considered natural preservatives enhancing safety quality
