Summary: The study found that exposure to polystyrene microplastics significantly altered the metabolism of marine medaka livers, leading to changes in various metabolic pathways and levels of specific metabolites. The effects of different sizes of microplastics (10-mu m and 200-mu m) on hepatic metabolism were observed, with differences in the impact on carbohydrate, amino acid, and lipid metabolism. Overall, the results provide new insights into the ecotoxicology of microplastics in aquatic organisms.

Summary: In recent years, the tricarboxylic acid cycle (TCAC) has been found to have non-canonical roles in living organisms, including plants and animals. These roles include physiological functions such as vacuolar function and redox regulation, as well as biological processes like signaling and cell differentiation. This review discusses the recent progress in understanding these non-canonical roles of TCAC metabolites, with a focus on their tissue-specific functions in plant development and their connections to phytohormone signaling pathways.

Summary: Prunus species are important stone fruits in the Mediterranean region, and rootstocks with specific adaptations are needed. Adventitious root formation is a crucial mechanism for stress tolerance in Prunus sp. Through the evaluation of hardwood cuttings from different rootstocks, genotype-dependent responses in rooting were observed. A time-series study revealed dynamic changes in endogenous hormone homeostasis, which may explain the differences in rooting performance.

Summary: Alkalinity is a major factor affecting crop production and its impact is worsened by climate change. Carbonates and high pH in soils negatively affect nutrient assimilation and photosynthesis, leading to oxidative stress. Modifying cation exchanger (CAX) activity could enhance alkalinity tolerance, as these transporters are involved in calcium signaling under stress. This study analyzed three Brassica rapa mutants and found that BraA.cax1a-7 mutation decreased tolerance to alkalinity, while BraA.cax1a-12 mutation increased tolerance by improving plant biomass, reducing oxidative stress, and enhancing photosynthesis.

Summary: The region of Murcia in southeast Spain has historically suffered from deforestation and desertification, leading to natural risks and tragic consequences. To combat this, a reforestation plan was implemented in the problematic river basins in the late 19th century. This study examined the changes in the Carrascoy y El Valle mountain system after reforestation and its impact on various environmental processes. Comparisons between photographs from 1928 and current satellite images showed a significant increase in tree cover, particularly in shaded areas. Unexpectedly, herbaceous and shrub cover was higher in sunny areas, possibly due to trampling in shaded areas. Overall, the reforestation efforts have had positive effects on the ecosystem, erosion, landscape, and climate, effectively slowing down desertification.

Summary: The industrial washing of corn grain during its milling generates a residue known as corn steep liquor (CSL), which is rich in nutrients that can promote plant growth. This study examined the effects of two CSL products (CSL-H and CSL-B) on pepper plants when applied through foliar and root application. Both methods increased plant size, with root application being more effective. The CSL products were found to enhance hormone synthesis, CO2 assimilation rate, and amino acid concentrations. Root application of CSL-H also increased the concentrations of specific amino acids. The results suggest that these products stimulate plant growth through hormone regulation and carbon and nitrogen metabolism.

Summary: In this study, the researchers investigated the role of endogenous auxin in microspore development in Brassica napus. They found that auxin concentration and the expression of auxin biosynthesis genes were high at early stages in the gametophytic pathway, but increased during microspore embryogenesis. They also discovered that inhibiting auxin biosynthesis reduced embryogenesis induction and embryo production, indicating that auxin is necessary for microspore embryogenesis initiation and progression.
