The distribution of vegetation in coastal wetlands is significantly influenced by soil properties. However, the mechanisms of how soil characteristics impact the physiological processes of forests remain underexplored. This study examined changes in the soil physicochemical properties and structural attributes of natural forests in the Yellow River Delta with increasing distance from the shoreline. trees were classified into healthy, intermediate, and dying categories based on growth potential, and dynamic changes in salt ions and non-structural carbohydrates (NSCs) were investigated. Results indicated that increasing distance from the shoreline corresponded to decreased soil salinity and pH, and increased soil moisture. mortality rate decreased, while tree height and ground diameter increased with distance. Soil salt content was positively correlated with mortality, but negatively correlated with tree height and ground diameter. Trees with lower growth potential had higher Na but lower K and K/Na ratio. Soil salt content was positively correlated with root and stem Na, while soil moisture was positively correlated with leaf NSCs. These findings suggest that soil salt content and moisture significantly influence ion absorption and NSC accumulation, with sodium toxicity being a key factor in the spatial distribution of forests.

Soil salinization is one of the main problems leading to a reduction in arable land area. In the present study, strongly salt-tolerant lines were screened for germination rates and physiological indices. The mechanism of saline-alkali stress tolerance in winter rapeseed was examined using transcriptome and metabolome analyses.

Soil salinization and ground water depletion are increasingly constraining crop production. Identifying useful mechanisms of salt tolerance is an important step towards development of salt-tolerant crops. Of particular interest are mechanisms that are present in wild crop relatives, as they may have greater stress tolerance than crop species.

Coastal wetlands contain very large carbon (C) stocks-termed as blue C-and their management has emerged as a promising nature-based solution for climate adaptation and mitigation. The interactions among sources, pools, and molecular compositions of soil organic C (SOC) within blue C ecosystems (BCEs) remain elusive. Here, we explore these interactions along an 18,000 km long coastal line of salt marshes, mangroves, and seagrasses in China.

Article Synopsis
- Stress in plants triggers changes in their traits, but it's unclear if these changes are direct responses to stress or influenced by shifts in soil microbial communities.
- In an experiment involving plants grown under different stress conditions, it was found that only live microbial communities led to delayed flowering in stressed plants, a response that proved to be maladaptive.
- The study indicates that microbes not only influence plant trait expression but also disrupt genetic correlations important for plant evolution, suggesting a significant role of soil microbes in shaping plant plasticity and evolution under stress.

Article Synopsis
- The study investigates how well a gut bacteria strain, Bacillus cereus AP-01, can break down low-density polyethylene (LDPE), using experiments over 28 days to measure its effectiveness.
- The researchers employed various methods like FTIR and SEM to analyze changes in LDPE structure and confirmed the bacterial strain through molecular characterization.
- Results showed that the bacteria significantly degraded LDPE, with a 30.3% weight loss and changes in mechanical properties, highlighting its potential as a solution for plastic pollution.
