Summary: The chemical interactions between fungal endophytes and plant leaves are likely to be the key mechanism affecting plant phenotypic traits. This study found that multiple fungal strains share functional similarities in their effects on plant growth and physiology under unstressed conditions. Plant metabolomics profiles were correlated with fungal treatments, and specific metabolites were associated with plant trait variation. These findings have implications for the development of metabolites as crop management tools.

Summary: Modern agriculture has negative environmental consequences, and scientists are searching for environmentally friendly alternatives to synthetic insecticides. This study examined the effects of four plant secondary metabolites, known as volatile organic compounds (VOCs), on the reproductive processes and larval hatchability of Tenebrio molitor beetles. The VOCs had varying effects on ovarian development, vitellogenin expression, patency index, egg laying, and larval hatchability. Additionally, the compounds showed a repellent effect and reduced insect survivability. Overall, VOCs have potential as bioactive compounds in plant protection.

Summary: Galls, which result from alterations in host plant tissues caused by parasitic organisms named gall inducers, can enhance the chemical and structural specializations of host plants. Superhost plants, capable of hosting multiple gall-inducing species, are found to have a high percentage of gall morphotypes and possess phytochemical and pharmacological potential. These superhost plants accumulate diverse secondary metabolites and exhibit antimicrobial and antioxidant activities, among other pharmacological properties. The specific chemical and structural features of host plants play a major role in arthropod-plant interactions. Testing the potentiation of such features in galls using selected superhosts is recommended.

Summary: This study investigated how BVOCs influence plant-insect communication, specifically focusing on the interaction between Japanese white birch and a leaf beetle in O3-polluted urban forests. Results showed that the leaf-emitted BVOCs play a role in attracting the leaf beetle, but the composition of BVOC blends varied among Betulaceae host trees. The presence of O3-reactive species in the emissions from white birch could disrupt the communication with the leaf beetle, suggesting a complex interplay between BVOCs, host preferences, and O3 pollution in plant-insect interactions.

Summary: Resource specialization and host-associated genetic differentiation (HAD) are important factors for the high diversity of plant-feeding insects. This study investigated the host-plant use and evolutionary patterns of leaf- and bud-galling sawflies collected from seven shared willow hosts. The results showed evidence for host specialization and HAD in both galler groups, but leaf gallers exhibited stronger specialization and cophylogenetic signal with their hosts compared to bud gallers. The findings suggest that evolutionary repeatability in host use and diversification of plant-feeding insects are influenced by stochasticity and lineage-specific effects.

Summary: This study investigated the allelopathic potential of different gall morphotypes of Eremanthus erythropappus on Lactuca sativa seeds. It was found that the pentacyclic triterpenes in the extracts of non-galled stems and stem galls had a strong allelopathic effect on seed germination. The galling activity also led to the synthesis and accumulation of new compounds while inhibiting the synthesis of previous compounds.

Summary: The super-host Mimosa gemmulata forms four different galls induced by congeneric Lopesia spp. These galls have distinct morphologies and their development is influenced by the inducer's manipulation of the host plant tissues. Anatomical traits related to trichome differentiation and vascular system arrangement are conserved in M. gemmulata, but altered under the influence of Lopesia spp. The formation of nutritive tissue varies among the different galls and is related to the induction site and original cell lineages. The peculiar traits of the globoid gall are due to its longer lifespan and stronger stimuli-induced responses in all host plant cell lineages.

Summary: The Caatinga environment imposes constraints on the phenology and development of host plants and their associated galls. The study on the Mimosa tenuiflora-Lopesia mimosae system reveals that phenological synchronism and structural strategies are key for gall survivorship in Caatinga. Phenological strategies involve synchronizing young galls with leaf sprouting in the rainy season and reproducing during gall senescence in the dry season. Structural strategies include tissue reorganization and compartmentalization to adapt to environmental constraints, and the predominance of periclinal cell elongation determines the gall's bivalve shape.

Summary: Research focuses on how senescent globoid stem galls induced by Neolasioptera sp. on Eremanthus erythropappus can still interact with ants and fungi, forming unique ant-nest galls. The anatomical analyses showed that ant activity in the gall chamber may prevent the closing of the exit channel, allowing the invasion of opportunistic fungal hyphae. This interaction among the plant, fungi, and ants leads to tissue responses and the maintenance of the peculiar ant-nest galls.

Summary: This study developed a plant model to investigate the interaction between Cryptococcus gattii and plants. The results showed that C. gattii can grow in plants without causing pathological effects. N. benthamiana exhibited higher proliferation of C. gattii, accompanied by an increase in hydrogen peroxide content, antioxidant system activity, and indoleacetic acid production. Colonies of C. gattii recovered from N. benthamiana displayed altered composition and morphology, as well as increased resistance to antifungal drugs. These findings suggest that plants may serve as a potential reservoir and transmission route for C. gattii.
