Summary: The study suggests that nutrient availability and host invasiveness are decoupled in this system, as increased nutrient availability did not enhance host success and abundance, and endophyte infection did not reduce plant community diversity.

Summary: Iron ore mining activity leads to significant waste production and impacts on surrounding ecosystems, especially during prolonged dry seasons. This study investigates the mechanisms of Paspalum densum grass in overcoming seasonal drought and metal accumulation in areas affected by iron mining in Brazil. The plants in the tailings storage facilities showed better survival and nutrition, with a higher metal concentration. The grass exhibited acclimatization and resistance to drought through antioxidant and photosynthetic adjustments, and was able to accumulate and translocate metals in plant tissues.

Summary: This study identified drought-tolerant genotypes in T. crinita and found that the tolerant accessions were more productive and had a better preserved plant photosynthetic activity under prolonged drought conditions. It also revealed that there is no direct relationship between drought tolerance and the level of aridity in the accessions' natural habitats, but rather suggests genetic heterogeneity and ample variation for drought tolerance in T. crinita natural populations.

Summary: In the current context of climate change and water deficit, the selection of native beneficial microorganisms, such as plant growth-promoting rhizobacteria (PGPR), has become a trend for sustainable agriculture. This study evaluated the production of melatonin (MT) by two native PGPR and their effects on endogenous MT levels in Arabidopsis thaliana plants under drought conditions. The results showed that these native PGPR improved plant tolerance to drought by producing MT, preventing oxidative and membrane damages, and promoting plant growth.

Summary: Drought poses a serious threat to global agriculture, particularly impacting soil biota and plants. Plant drought resistance is a complex quantitative trait controlled by multiple genes, with research indicating various strategies to cope with drought stress, yet the role of the rhizosphere remains largely overlooked. Therefore, an integrated rhizosphere management strategy may be an effective approach for mitigating drought stress.

Summary: A growing body of evidence indicates that biological invasions are causing changes in the composition of species in communities over space and time. Previous studies conducted at small scales and short durations may have underestimated the impact of exotic species on native communities.

Summary: Water availability has a significant impact on plant-herbivore interactions. This review summarizes recent research on the effects of water availability on plant antiherbivore defense and the physiological processes involved. Water deficit tends to enhance certain defense traits but negatively affects others, and the impact of water availability on species interactions and plant evolution is discussed. However, there is a lack of study on the interactive impact of additional abiotic stressors on water-plant-herbivore interactions.

Summary: There is a close relationship between plant stem moisture and drought stress. This study analyzed the variation of stem water content under drought stress for different plants. The results showed that large mature trees have stronger resistance to drought stress and can maintain stem water content for a longer time, while small plants are more vulnerable to air embolism and have weaker recovery abilities. There is a threshold of plant death at a drought stress level of 70% and beyond, where stem water is irreversibly lost and cannot be restored even with watering.

Summary: Drought is a global threat that affects agricultural production. Plants have evolved several adaptive strategies to cope with drought, among which stomatal closure is a critical mechanism. Abscisic acid, reactive oxygen species, and calcium ion play pivotal roles in controlling stomatal closure.

Summary: Drought is a critical factor affecting plant survival in the desert ecosystem. Native desert plant species show efficient water use and tolerance to drought. Different desert grass species respond differently to drought stress, but they can still efficiently use water and produce stable dry matter yield and nutritive value under moderate drought conditions. Increased root biomass helps with water absorption and survival. Drought stress also affects protein and ash content.

Summary: The study demonstrates that overexpressing PtaERF194 can enhance plant drought tolerance by improving water use efficiency, limiting water loss, and maintaining high water potential. Conversely, RNAi plants showed similar morphology and physiology to the wild type, indicating redundancy of the function of PtaERF194 with other ERF transcription factors.

Summary: In recent decades, the spread of Elymus athericus has significantly altered the plant community composition and ecosystem services of European marshes. Two ecotypes of E. athericus, adapted to high-marsh and low-marsh environments respectively, have been identified. The plant's ability to oxygenate its rhizosphere, especially during light exposure, contributes to its competitive advantage in low-marsh areas and may aid in its spread under conditions of accelerated sea-level rise.

Summary: The study utilizes a combinatorial engineering approach to optimize plant signaling networks for improved drought tolerance and growth under water-limiting conditions. Targeted introduction of a specific gene combination enhances plant survival under drought without the need for prior understanding of network function.

Summary: Some lineages of the orchid genus Ophrys exhibit high diversification rates. A hybrid assembly approach using genomic data successfully assembled whole plastid genomes for two new Ophrys species. The research supports the placement of the O. insectifera clade as sister group of non-basal Ophrys.

Summary: The agroecological transition of agriculture requires changes in practices, ways of thinking, and underlying values. Adapting broad scientific principles to the singularities of each farm can help identify evidence-based practices for local practitioners. Managing the agro-ecological transition is better conceived as a value-based process rather than an evidence-based one.

Summary: Signatures of local adaptation were not found in adult plants of two subspecies of snapdragon plants, with populations from low-elevation habitats outperforming those from high-elevation habitats in all garden experiments. The effects of phenotypic traits on fitness proxies were similar at high and low elevations, suggesting no divergent selection based on elevation. Different traits had varying effects on fitness proxies in the two subspecies, indicating potential differences in adaptive processes at the scale of A. majus subspecies.

Summary: Supporting farmers in their transition to sustainable agricultural practices requires addressing the uniqueness of their individual situations. We propose a 5-step approach based on pragmatic inquiry and community of practice, which involves clarifying changes, mapping them, recording surprises, questioning collective action and organization, and reorienting individual projects to match collective actions in the agro-ecological transition.
