Summary: Extreme temperatures, drought, salinity, and soil pollution are common abiotic stresses that can negatively impact plant productivity and survival in fields. Plant responses to these stresses involve various molecular mechanisms, including perception, signaling, transcriptional reprogramming, and protein modifications. Flowering development is particularly vulnerable to environmental stress, as it affects reproduction and crop profitability. The Poaceae family, comprising important crops like wheat, barley, and rice, experiences stress-induced changes in flowering time and development, leading to yield losses. Understanding the molecular pathways linking flowering control to extreme environmental conditions in monocots can provide insights for biotechnological strategies to ensure agricultural stability in changing climates.

Summary: The main threats to chestnut in Europe are climate change and emerging pathogens. This study aimed to investigate the combined effects of global warming and Phytophthora cinnamomi (Pc) infection on chestnut seedlings. Results showed that plant growth and root biomass were significantly higher under high ambient temperature compared to ambient temperature and heat wave event. Secondary metabolite compounds in leaves and roots were also altered significantly with temperature. Pc infection had a significant impact on the secondary metabolite profile of plants, and the group of trees that best survived Pc infection exhibited specific changes in metabolite composition. This is the first study to address the combined effects of global warming and Pc infection in chestnut.

Summary: This study investigated the use of a temporary immersion bioreactor system for screening heat tolerance in potatoes, identifying Reveille Russet as a promising heat-tolerant variety and confirming Russet Burbank and Atlantic as susceptible checks. The study also showed that hormone-free microtuberizing media with 8% sucrose could enhance microtuber number and size, while incubation at 30 degrees C had varying effects on different potato clones in terms of microtuber number and weight. In general, heat stress increased total biomass of plant tissues but the responses of potato clones to heat stress differed.

Summary: Plant secondary metabolites (PSMs) are crucial for human health and serve as the foundation for many pharmaceutical drugs. Obtaining natural products, particularly from endangered species, poses a challenge for drug discovery and the pharmaceutical industry. Plants affected by abiotic stress can potentially serve as an alternative source for drug discovery by producing a diverse range of PSMs to combat environmental stressors. These PSMs, primarily synthesized under abiotic stress conditions, often possess anti-inflammatory and antioxidant properties.

Summary: This study examines the impact of climate change on regional inequality using detailed data on meteorological factors and local fiscal stress. The results show that climate change-induced high temperatures can lead to an increase in local fiscal stress, thereby contributing to regional inequality in multiple ways. Nonlinear effects of high temperatures on fiscal stress are also observed, with significant impacts only when the daily mean temperature exceeds 32°C. Additional tests reveal higher sensitivity to high temperatures in hot regions, eastern China, regions with higher population density, developed regions, and counties with worse fiscal performance. This paper provides a more comprehensive understanding of the impacts of climate change and improves the accuracy of estimating its adverse effects.

Summary: Soil salinization processes have increased and negatively impact agricultural fields. This review highlights the potential effects of soil salinity on plants, including decreased leaf development rate, reduced water level and cell division, low photosynthetic rate, stomata closure, and limitations on seed germination. However, there are also positive aspects such as activating pathways for salt stress resistance and benefiting physiological parameters like germination and stomata number. Further studies should focus on both the positive and negative aspects of soil salinity increase.

Summary: The blue shark is a widely distributed top predator, classified as Critically Endangered in the Mediterranean Sea and Near Threatened globally. Genetic studies have previously suggested a single global population. However, this study used a genome-wide approach and revealed two main groups, the Mediterranean Sea and northern Atlantic samples differentiated from Indo-west Pacific samples. Within the Atlantic Ocean, further genetic differentiation was observed, as well as between the Atlantic Ocean and the Mediterranean Sea. The results highlight the importance of considering genetic population structure and demographic history in the management and conservation strategies of the blue shark.

Summary: Through biophysical modeling and network analysis, we demonstrate that oceanographic connectivity can explain the genetic differentiation of mangrove populations, regardless of species, region, or genetic marker (significant regression models in 95% of cases, with an average R-square of 0.44 +/- 0.23 and Person's correlation of 0.65 +/- 0.17), systematically improving traditional isolation-by-distance models. Important connectivity indices also play a crucial role in explaining differentiation (R-square improvement of 0.06 +/- 0.07, up to 0.42). We further show that ocean currents produce skewed dispersal kernels for mangroves, highlighting the role of rare long-distance dispersal events in historical settlements.
