Summary: This study identified a gene defect responsible for low PSSR in wild rice and revealed the discrepancy of crossover rates between indica and japonica subspecies. The findings suggest that the low fertility in wild rice may be caused by different gene defects, and indica and japonica subspecies have substantially different CO rates responsible for the discrepancy between the fertility of mlh1 and mlh3 mutants.

Summary: Domestication of rice increases the alpha diversity of rice rhizosphere fungal community compared to wild rice, but decreases the complexity of the fungal community. Specific rare taxa were enriched in the rhizosphere of domesticated rice, and the relationships with arbuscular mycorrhizal fungi (AMF) and soilborne fungi differed compared to wild rice. These findings suggest potential sources for bio-inoculation to reshape the rhizomicrobial community of domesticated crops for sustainable agricultural solutions.

Summary: This study investigated the core rhizomicrobiome of a wild plant species transplanted to soil with small differences in chemical factors and examined the impact of these soil chemistry differences on the core microbiome after long-term cultivation. The results showed that the core microbiome plays a role in improving nutrient resource acquisition for rice growth, with nitrogen, manganese, iron, and carbon resource acquisition being potential functions. The function of the core bacterial community in the rhizosphere was significantly influenced by electrical conductivity, total nitrogen, and available phosphorus in the soil adhering to the roots.

Summary: This study compared the endophytic bacterial and archaeal communities in the rhizome of Oryza longistaminata with other compartments, revealing low taxonomic and phylogenetic diversity as well as the lowest network complexity in the rhizome. The major genera identified in the rhizome were Streptococcus, Bacillus, and Methylobacteriaceae, with specific ASVs present in the rhizome. The study also found noteworthy type II methanotrophs across all compartments, potentially benefiting the host by facilitating CH4-dependent N-2 fixation under nitrogen nutrient-poor conditions.

Summary: Rice is a vital food source for half of the world's population, and its demand is increasing due to population growth and climate change. This study analyzed seed traits and their impact on seedling vigour and grain yield in wild and cultivated rice species. Seed size and shape significantly affected embryo length, seedling traits, and grain yield. Larger seeds had better seedling vigour, and cultivated Oryza sativa genotypes had the largest embryos and seed areas. Seed size was shown to evolve under selection pressure, with larger seed sizes indicating improved fitness under agronomic conditions.

Summary: Passive sampling is used to quantify the net partitioning of hydrophobic organic contaminants between porewater and solid phases in contaminated sediments, improving risk management strategies. Direct measurements of porewater (C-free) are the most accurate way to predict adverse effects on biota. A stochastic framework is proposed to map solid-phase concentration (C-total) to estimated C-free by considering variability in passive sampling-derived K-TOC relationships.

Summary: Vegetated coastal ecosystems are efficient in carbon sequestration compared to terrestrial ecosystems. However, current land surface models lack representation of coastal wetlands. This study aims to improve modeling of vegetation in terrestrial-aquatic interfaces, specifically focusing on coastal and estuarine ecosystems. The researchers identify guiding questions, potential simulations, and data needs to enhance the representation of vegetation in these ecosystems and discuss the importance of including separate plant functional types for different wetland vegetation. They also highlight the drivers and consequences of shifts in dominant plant functional types.

Summary: Riverine macrophytes play crucial ecological roles in river ecosystems, but their growth models have received relatively limited attention compared to other aquatic or terrestrial plants. This systematic review reveals that current models often overlook important factors such as shading and the role of macrophytes in nutrient cycles. Future research should focus on exploring these factors and developing a conceptual framework to guide macrophyte growth modeling. Emphasizing modularity and accessibility is also important for improving efforts to model and manage riverine ecosystems.

Summary: Bryophytes can play a significant role in ecosystem processes and hold potential as bio-indicators for monitoring environmental pollution. This study examined the effects of NO3- pollution on the elemental composition of aquatic and semi-aquatic bryophytes and identified suitable species as bio-indicators. Higher NO3- concentrations were found in spring water from intense farming and urban areas, positively correlated with N content and delta N-15 isotope ratio in bryophytes. Apopellia endiviifolia and Oxyrrhynchium speciosum were highlighted as promising candidates for bio-indication of aquatic NO3- pollution.

Summary: This study investigated the seed production, seed banking, and germination cues of sub-tropical Vallisneria americana. It was found that the seeds of sub-tropical populations were dormant and could only germinate in the presence of organic material, light, or following scarification. Germination rate was enhanced by the presence of low-oxygen organic sediments and ethanol. These findings suggest a germination strategy focused on exploiting openings in existing vegetation following disturbance.

Summary: Constructed wetlands treating runoff from agricultural catchments can reduce nutrient load of water, but they can also be significant sources of greenhouse gases, especially methane. This study assessed methane emission potentials and phosphorus removal efficiency in a 0.45 ha in-stream surface flow constructed wetland, and analyzed the temporal dynamics of methane emissions and phosphorus removal over a nearly 4-year period. The results showed a clear seasonal dynamic in phosphorus removal efficiency and an increasing trend in methane emissions over the years, with the majority of methane fluxes occurring during the warm period. Maintenance of the wetland and regular removal of aboveground vegetation can reduce methane emissions, and regular sediment removal is also necessary due to phosphorus saturation.

Summary: Nutrient availability and light intensity play important roles in the expansion of amphibious clonal plants from terrestrial to aquatic habitats. High nutrient levels and light conditions promote the growth of the apical portions and overall performance of the clones. Maintaining clonal integration can benefit the expansion of the plants by optimizing resource utilization. These findings have implications for predicting community dynamics and vegetation restoration in ecotones like wetlands.
