Summary: The carpel is a crucial reproductive organ in flowering plants, playing a key role in ensuring protection, fertilization, and fruit development. Research on the mechanisms of carpel development in grasses is relatively limited but progressing, focusing on aspects such as carpel identity determination, morphogenesis, and floral meristem determinacy. The genetic and molecular aspects of carpel development in grasses are compared and contrasted with the extensively studied model eudicot plant Arabidopsis.

Summary: The appearance of the flower is a significant event in the evolutionary history of plants, with the gynoecium being a key organ that provides adaptive advantages. The gynoecium protects and facilitates fertilization of the ovules, which develop into seeds. In many species, the gynoecium itself becomes the fruit, aiding in seed dispersal. Despite recent advances in understanding the genetic regulatory network of gynoecium development, questions remain about the conservation of molecular mechanisms across different taxa and the origin of gynoecium diversification.

Summary: The all-flesh type of tomato fruits is caused by mutation of the MBP3 gene, however, knocking down MBP3 in certain genotypes also affect plant and fruit development. Here, the authors show that a natural mutation of AGL11, a close homolog of MBP3, is responsible for the phenotypic divergence.

Summary: This study investigated the AP2/ERF superfamily in pecan and identified 170 gene members, which were further classified into different subfamilies and groups. Analysis of gene structures and conserved motifs revealed high conservation within each group. Various cis-elements were detected in the promoter region of CiAP2/ERF genes. Transcriptome data and qRT-PCR analysis suggested that certain subfamilies had a positive response to waterlogging stress. Subcellular localization experiments showed that some genes were localized in the nucleus and had self-activation ability.

Summary: Individual recognition is crucial for social interactions and often occurs through acoustic signals in birds and mammals. The study on the Cape fur seal (CFS), one of the most colonial pinniped species, showed that affiliative and territorial vocalizations display higher degrees of individuality compared to other pinniped species, possibly due to higher ecological constraints. This research sheds light on how environmental and social factors influence communication systems in vertebrates.

Summary: The success of angiosperms, the most successful group of land plants, is mainly attributed to the gynoecium, the innermost whorl of the flower. In Arabidopsis, the gynoecium is formed by two fused carpels, and a quasi-meristem called the carpel margin meristem plays a crucial role in its development. The study of gynoecium development, which is important for the production of seeds and fruits, has been a significant task for the scientific community. This review presents recent advances in Arabidopsis gynoecium patterning and highlights unanswered questions.

Summary: The plant ovule is a crucial organ that directly leads to seed formation, with its number and flower fertility being significant factors influencing yield. Studies have shown challenges in increasing one without compromising the other. Recent findings highlight regulatory pathways in Arabidopsis and cereal crops that could help overcome this yield constraint by targeting hormones and transcriptional regulators in the optimization of reproductive traits.

Summary: This study provides a new interpretation of a fossil genus, Santaniella, as belonging to the magnoliid clade instead of the presumed Ranunculaceae. The researchers used a new fossil specimen and conducted a phylogenetic analysis using morphological and DNA sequence data. The results indicate that Santaniella is an angiosperm but its combination of characters does not strongly support a close relationship to any extant order of flowering plants.

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.
