Summary: Comparative spectrochemical analysis of sampled pinnules from Odontopteris schlotheimii Brongniart and Odontopteris cantabrica Wagner revealed that they are predominantly aliphatic with highly cross-linked carbonyl groups and low condensation degree of benzene rings. These chemical parameters can be used to distinguish between the two species.

Summary: The study investigated the structural and functional properties of Citrus grandis Osbeck seed mucilage obtained through different extraction methods. The findings revealed that CGO seed could serve as an excellent source of high methoxyl pectin with high intrinsic viscosity and molecular weight. The UAEE method with Celluclast(R) 1.5 L showed the highest extraction yield. EAE with cellulase had a negative impact on the purity of pectin. Overall, EAE with Celluclast(R) 1.5 L, followed by UAE and UAEE with Celluclast(R) 1.5 L, were the least affected extraction methods.

Summary: This study fabricated large area defect-free continuous functional material layers by compounding TT-COFs with built-in formyl groups on graphene oxide. The material layers showed extraordinary host-guest interactions, specifically rejecting dye molecules, leading to high rejection rate and large flux. This simple and effective method demonstrated the utility and high efficiency of TT-COFs as an advanced material platform for dye removal.

Summary: Plant growth-promoting Rhizobacteria (PGPR) have beneficial effects on plant growth through various interaction mechanisms with plants or other root-associated microorganisms. This study evaluated the impact of seed inoculation with phytostimulatory PGPR Azospirillum lipoferum CRT1 on selected microbial functional groups important for maize growth in the rhizosphere. The results showed that inoculation enhanced maize growth and increased the size of functional groups. Moreover, the ecological effects were field-specific and varied with the use of the inoculant in different field sites and growth stages for diazotrophs and ACC deaminase producers.

Summary: The article describes the discovery of the only known lyginopterid cupulate seed collected from the Sydney Coalfield in Nova Scotia, Canada, which consists of a coalified cupule surrounding an ovate structure interpreted as an ovule. Despite the incomplete nature of the specimen, this finding is significant for enhancing our understanding of the flora of the Sydney Coalfield.

Summary: Amber from the Carboniferous sedimentary rocks of the Sydney Coalfield in Nova Scotia, Canada has been discovered. The amber, found in the form of droplets and linear features, ranges in color from light brown to dark purple. It was associated with abundantly abscised pinnules of the seed fern Linopteris obliqua. The discovery expands the age range of amber to approximately 300 million years and demonstrates the biosynthetic ability of Carboniferous seed ferns to produce resinous exudates.

Summary: Seed germination is a crucial stage in plant life cycle and can be affected by temperature and light. This study found that low temperature had a negative impact on seed germination of all functional groups, while darkness reduced germinative force and duration. The interaction of light and temperature strengthened the inhibitory effect of low temperature on seed germination of grass functional group.

Summary: Nutrient addition can affect soil nutrient content, soil microorganism diversity, and structure. This study explored the effects of different levels of N/P/K fertilization on bacterial and fungal communities in Torreya grandis soil. The results showed that fertilization led to changes in the abundance and pathways of bacteria and fungi in both bulk and rhizosphere soils. The chemical properties of the soil were also significantly affected by the fertilization levels.

Summary: The relationships between morphological fruit types, colors, seed colors, and functional plant traits were studied in 1,139 plant species from different plant communities. The study found that fruits were predominantly dark in color, seeds had both dark and light colors, and there were associations between fruit types and common colors. Different plant types and environmental conditions displayed varying characteristics in fruit morphology and colors.

Summary: The influence of gamma-irradiation dose on the composition of functional groups on the surfaces of oat grain shell, kernel, and seed powder has been studied. Within a certain dose range, gamma-irradiation caused changes in the absorption bands and surface continuity of oats, but did not completely destroy the chemical bonds in the compounds. Higher doses led to loss of hardness, filminess, and disrupted surface continuity in the oats, as well as color changes due to carbonization and oxidation of grain macromolecules.

Summary: Selected pygidia of the middle Cambrian trilobite Athabaskia anax from San Isidro, Argentina were analyzed for the first time using SEM-EDX, revealing four types of morphological preservations. Results suggest that chemical and structural changes during fossilization may cause differences in morphological characteristics and caution should be exercised when erecting new taxa based on exoskeleton morphology.

Summary: This study reports well-preserved Late Pennsylvanian plant fossils from the Southern Anthracite Field in the USA. The fossils are physically associated with an assumed anthracitic axis and demonstrate two preservation modes of plant material in a metamorphic environment. The hypothesis of an organometallic process provides potential for novel research in plant-fossil preservation in anthracitic terrain.

Summary: This study aimed to provide a deeper understanding of the organic matter characteristics that determine the concentrations of PBDEs in sediments. By analyzing sediment samples from Mendoza province, Argentina, and using multivariate learning methods, the study compared environmental and experimental models. The results showed that PBDE concentrations in sediments were correlated with degraded organic matter and higher organic matter density values.
