Summary: Anthropogenic activities have resulted in an increase of nitrogen compounds in the atmosphere, affecting forest ecosystems. This study simulated the effects of nitrogen deposition in beech forests through controlled experiments in two contrasting climatic regions. The results showed that nitrogen addition had some impact on forest health, but no severe impairments were observed in the short term.

Summary: Bagging treatment has a significant impact on the nutritional quality and color of yellow-fleshed kiwifruit, promoting the degreening of mesocarp and increasing brightness. It reduces the accumulation of dry matter, titratable acids, starch, sugars, chlorophyll, carotenoids, and ascorbic acid, while increasing their content after debagging. Bagging affects the expression of key genes involved in chlorophyll, carotenoid, and ascorbic acid metabolism in kiwifruit during fruit development.

Summary: In this study, a unique strategy was demonstrated to disperse various plant pigments by high-speed shear-force mixing of fresh bell peppers in an aqueous medium, followed by centrifugation and filtration. The resulting dispersion allowed simultaneous probing of chlorophylls, phenolic compounds, and carotenoids through fluorescence excitation-emission mapping and optical absorption analysis. This sampling protocol and spectroscopic analysis will be highly beneficial for obtaining advanced spectroscopic databases and rapid food analysis and quality control.

Summary: A mutant variant of Yanling Yinbiancha with green leaves has been identified, which is different from the original albino leaves. Transcriptomic and metabolomic analysis revealed differentially expressed genes and metabolites between the two variants. The differences between green and albino leaves may be associated with the synthesis of anthocyanins, chlorophyll, and carotenoids.

Summary: The study tested three gall morphotypes induced by Cecidomyiidae on leaflets of Inga ingoides and found that different gall types exhibit differences in cytological and metabolic traits, as well as in the accumulation of primary metabolites. The presence of fungi influences the system but does not define exclusive features for specific gall types, with distinct cytological mechanisms identified for each gall type in terms of food resources availability.

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 cytological and histochemical features of galls can be changed by parasitoid attack. By studying two tri-trophic systems as models, we found that parasitoids caused distinct cytological responses and had no impact on histochemical profiles of the galls compared to non-parasitized conditions.

Summary: Gall structures and their associated host plants exhibit distinctive structural and histochemical adaptations to survive in the challenging environment of restingas. These adaptations include the presence of thick cuticles, the accumulation of polyphenols and lignified cell walls, and the reorganization of host tissues. Different gall development patterns and host tissue modifications facilitate water accumulation and protect the gall inducers against environmental stresses and enemies.

Summary: Piptocarpha macropoda is a plant species that can develop globoid galls induced by insects. These galls can be attacked by parasitoid insects, which have a positive impact on gall size and nutritive cell layers. However, the parasitoid insects do not affect the size of the host insects, indicating an overstimulation on plant cells and tissues by the parasitized insects.

Summary: Wetlands play a crucial role in terms of biodiversity, carbon storage, and hydrological processes. Veredas wetlands in Brazil's savanna are protected areas that provide water to main rivers and support endemic species. However, there is a lack of large-scale information about these wetlands. Using remote sensing data, this study explored the factors influencing the occurrence of Veredas wetlands in a specific region of Brazil. The results showed that Veredas were more frequent in the western part of the region, characterized by lower altitude, temperature, and precipitation seasonality, as well as specific soil and land use patterns. This assessment can contribute to the development of conservation strategies and biodiversity studies.

Summary: This study evaluated the impact of root-knot nematode infection on the agronomic traits, histology, and cell wall components of parsley, with a focus on giant cell formation. The results showed that Meloidogyne incognita infection affected the development of parsley, reducing root weight, shoot weight, and height. Giant cell formation caused disorganization of the vascular system and had a negative effect on the development of the crop.

The morphology and histological features of galls depend on the galling insect taxa and the targeted plant organ. The study found that the galls induced by Palaeomystella oligophaga on Macairea radula are stem-like galls with stem-branch vascular connections, which provide shelters for various arthropods.

Summary: This study investigated the interaction between iron excess and phosphorus deficiency in Paspalum densum. The results showed that iron excess decreased phosphorus concentration in roots, while phosphorus deficiency increased iron concentration in leaves. Stomatal limitation was the main cause of decreased photosynthesis due to iron excess. Phosphorus deficiency contributed to higher phosphorus use efficiency and biomass.
