Summary: This study investigated leaf epidermis anatomical characteristics and taxonomic significance of four species from four different genera of the Scrophulariaceae family collected in northern Pakistan. By examining qualitative and quantitative foliar epidermal features, differences in stomata and trichomes were identified, leading to successful species delimitation and identification using principal component analysis and cluster analysis based on micromorphological characters. A taxonomic key based on foliar epidermal characters was provided for distinguishing and identifying the studied taxa.

Summary: This study investigated the fruit and seed characteristics of twelve species from the genus Alyssum in different populations in Eskisehir, Turkey. Morphological and micromorphological studies were conducted to determine the systematic relationships of these species. Numerical analysis techniques including clustering and principal component analysis were employed. The results highlighted important characters for the classification of Alyssum.

Summary: The study examined trichome types, distribution, and pollen morphology in nine Micromeria taxa and five closely related Clinopodium species from the Lamiaceae family of the Balkan Peninsula. The results revealed differences in trichome structures and supported the recent transfer of Micromeria species from the section Pseudomelissa to the genus Clinopodium.

Summary: This study investigated the pollen morphology of 17 species of Astragalus sect. Aegacantha in Pakistan. The results showed that the quantitative characters of pollen morphology are the most reliable characters for species delimitation and are partially consistent with the general morphology. Furthermore, the pollen traits provide a baseline for phylogenetic optimization in this section of Aegacantha.

Summary: The purpose of this study was to examine the morphological characteristics of glandular and non-glandular trichomes in leaves of Phlomis herba-venti subsp. Pungens using different microscopy techniques. Two types of non-glandular trichomes were identified: unicellular and branched, while glandular trichomes were categorized as capitate and dendroids. Histochemical analysis revealed distinct secretion products in each type of glandular trichomes. The dendroid trichomes were described and characterized for the first time in P. herba-venti.

Summary: Marrubium friwaldskyanum Boiss (Lamiaceae) is a Bulgarian endemic species with different essential oil composition compared to other Marrubium species. The harvest stage and grinding of biomass prior to extraction have significant effects on the concentration of certain essential oil constituents.

Summary: In the study, Solanum viarum Dunal was found to have the potential to accumulate hazardous heavy metals, including lead, cadmium, and zinc. The plant showed better germination percentage and accumulated high concentrations of these metals in its tissues under toxic conditions. It also exhibited positive modulation in physiological performances and antioxidant activities, suggesting enhanced tolerance and membrane stability. The study provides insights into the mechanisms that make S. viarum a potent accumulator and offers information for phytoremediation.

Summary: Mycocaliciales is a group of non-lichenized fungi found in temperate and tropical regions, including saprotrophic and lichenicolous species. This study used molecular data and re-examined type specimens to determine the systematic position of the genus Pyrgidium, providing detailed morphological descriptions and illustrations.

Summary: This study examined the surface and external structure of petals, sepals, hypanthium, and pedicel of eight Rosa species. Micromorphological investigation using scanning electron microscopy revealed the distribution and dimension of different trichome types in the analysed plant parts. Results showed variations in trichome types among the analysed species, providing valuable information for plant determination.

Summary: This study utilizes SEM, PCA, and ANN to construct a hybrid model for predicting WUE. The application in Kashgar, Xinjiang, China shows that different factors have diverse influences on WUE, and the ANN structure optimized by SEM fits better. The PCA-SEM-ANN model has high explanatory power and precision, providing a theoretical basis and simulation method for improving water use efficiency and predicting future responses to climate change.

Summary: Leaf morphology and epidermal characters of 11 species of the genus Cleome from Pakistan were studied using light and scanning electron microscopy. The study found that Cleome is characterised by amphistomatic leaves with great polymorphism in shape, with actinocytic and anomocytic stomata being most prevalent. Glandular hairy type of indumentum is the most dominant within the genus, and quantitative characters such as leaf size and stomatal frequency are well correlated with the qualitative features of leaves.

Summary: This study aims to explore the genetic regulatory network underlying multicellular trichome development in Aristolochia. By comparing two different morphological species of Aristolochia, we found significant modifications in gene composition, expression, and function compared to model plants. We propose the first hypothetical genetic regulatory network for floral multicellular trichome development in Aristolochia and identify key factors responsible for the presence and specialization of floral trichomes in different species.

Summary: With the increasing global warming and frequent natural disasters, the world has adopted new industrial models to reduce such problems. China, in its search for new economic growth points, has also seen the emergence of low-carbon industries. This study evaluates the key factors of low-carbon industry competitiveness through questionnaire data and uses principal component analysis to construct a comprehensive competitiveness model. The results show that industrial support factors, enterprise's own production factors, and ecological factors are critical for the development of low-carbon industries.
