Summary: Global change has significant impacts on grassland diversity. Plant offspring selected under high diversity conditions produce more biomass than those selected under low diversity conditions under nitrogen addition. Soil and plant history also have species-specific effects on trait expression.

Summary: This study compared the metabolic profiles of Dactylis glomerata leaves collected at different altitudes on four islands of the Aeolian archipelago. It was found that samples from Stromboli were significantly different from those collected on other islands, with increasing altitude leading to changes in the metabolites of the grass.

Summary: This study proposes a rapid analysis method for assessing the hygienic quality of orchardgrass silage by determining the ergosterol (ERG) and polyphenol contents using high-performance liquid chromatography and UV/Vis spectrophotometry. The results show that ERG and polyphenol contents are reliable indicators of fungal contamination in silage grass.

Summary: In pasture-based dairy systems, grazing management strategies have mainly focused on maximizing herbage harvest per hectare, while strategies to maximize herbage intake rate have been explored recently. This study aimed to evaluate the effects of different grazing management strategies on herbage nutritional value, intake, and milk production of dairy cows, and to investigate the impact of concentrate supplementation.

Summary: This study isolated plant-growth-promoting endophytes (PGPE) from Dactylis glomerata and evaluated their effects on plant growth. The results showed that these endophytes were able to produce high levels of IAA, dissolve inorganic phosphorus, and exhibit antagonistic effects against various plant pathogens.

Summary: Zinc is essential for plant growth, but excess amounts can be toxic. This study investigated the effects of different levels of zinc application and organic fertilizers on the yield and zinc uptake of cocksfoot. Results showed that higher levels of zinc application increased zinc content and uptake in cocksfoot, but decreased the bioaccumulation factor. Organic fertilizers increased the yield and zinc uptake of cocksfoot, with different materials showing different tolerance indices towards zinc.

Summary: This research aimed to isolate and characterize nonrhizobial endophytic bacteria from root nodules of Medicago sativa L. and Lotus corniculatus L. with plant growth-promoting characteristics. The most promising strain, Bacillus megaterium DZK1BH, showed the best attributes for plant growth promotion and could potentially be used as a biofertilizer for growing Lotus corniculatus and Dactylis glomerata in acid soils.

Summary: Orchardgrass is an important perennial forage, with research showing differential expression of DgWRKY genes under various environmental stresses, especially under rust infection. The study suggests that DgWRKYs and RGAs may synergistically respond to orchardgrass' response to rust.

Summary: Erica australis plants have been traditionally used for their medicinal properties, and a recent study has demonstrated their antioxidant, antibiotic, anti-inflammatory, anticarcinogenic, and antitumoral activities, attributed to high anthocyanin content. The research aimed to optimize an ultrasound-assisted extraction method for anthocyanins in E. australis flowers, using a Box Behnken design and specified variables. The developed method showed successful extraction of anthocyanins and has been found to be applicable to other Erica species.

Summary: The study found that measuring resource capture or biomass production provides different insights into how competitors interact and their relationship with the environment, and that biomass serves as a long-term integrative proxy for the outcomes of multiple separate interactions occurring among plants.

Summary: This study investigates the transcriptional activity of candidate genes related to adaptation to chronic radiation exposure in plant populations from radioactively contaminated territories. The results show that these plants exhibit upregulation of specific homologs in response to stress, including genes associated with water and hydrogen peroxide transport, intensity of photosynthesis, and stress responses. The methodological approach described in this study may facilitate large-scale screening of candidate genes in various plant species abundant in radioactively contaminated areas.

Summary: Exposure to high Mn concentration led to decreased biomass accumulation, affecting photosynthetic pigments and biochemical indicators in Erica andevalensis. Toxicity symptoms like chlorosis in tip leaves were detected, while the species showed tolerance to high Mn concentrations without significant toxicity.

Summary: The study highlights the importance of considering soil systems in plant reintroduction planning, especially in saline environments. It also suggests that using Technosols and brackish water irrigation may be beneficial for reintroducing rare halophyte species in native habitats. The results show that plants grown in Technosols exhibited better growth and physiological status compared to those in conventional soils, indicating the potential of eco-friendly soil technology approaches in conserving endangered plant species.

Summary: This study investigated the impact of AMF inoculation on grapevine performance in Cu contaminated soils, with or without the presence of EDTA chelates. Results showed that AMF inoculation can enhance root biomass, but may have negative effects on plants when EDTA is present, including decreased root biomass and stimulated Cu translocation to leaves.

Summary: The study found that L. pedunculata plants, regardless of their origin, activate defense mechanisms against oxidative stress caused by high concentrations of metal(loid)s. When seeds come from contaminated areas, they have a better growth capacity when sown in uncontaminated soils. This has significant implications for using this species to rehabilitate soils with high metal(loid) contents.

Summary: This study investigates the use of C. salviifolius to stabilize gossan mine wastes amended with organic and inorganic wastes for faster environmental rehabilitation. The mine wastes have high concentrations of PHE and low concentrations of organic carbon and nutrients. The best vegetative development occurs in Technosols containing a mixture of agriculture residues, with no visible signs of toxicity.

Summary: Coastal ecosystems play a crucial role in coastline changes and climate change impacts, while land-use planning strategies are essential for ecosystem stability and resilience. The study compared different methodologies for mapping protection areas near cliff crests and proposed a CPZ model to contribute to discussions on best land use practices in these areas. Results showed that the CPZ model could protect a wider area compared to the current Portuguese legal framework, emphasizing the importance of careful land-use planning in coastal zones.
