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: Mentha canadensis is an important spice crop and medicinal herb with high economic value. A non-specific lipid transfer protein gene (McLTPII.9) from M. canadensis was cloned and identified, which may positively regulate peltate glandular trichome density and monoterpene metabolism.

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: The study proposes a technical route to distinguish peltate glandular trichomes (PGTs) and extract their spatial phenotype. It is found that the development of PGTs is correlated with the growth of the entire leaf, and can be identified based on the leaf veins. A linear regression model illustrates the relationship between spatial phenotype and metabolite content of PGTs.

Summary: This study examined the morphology and metabolites of peltate glandular trichomes (GTs) in Mentha haplocalyx Briq. It was found that the peltate GTs possessed globular dome shapes and intense auto-fluorescence. The secretions of peltate GTs contained anthraquinone, flavonoids, phenolic acid, and terpenoids. The peltate GTs were shown to be the primary site of volatile and non-volatile compounds in M. haplocalyx.

Summary: Glandular trichomes in medicinal plants play a crucial role in the synthesis, storage, and secretion of secondary metabolites, which are important in exploring the quality of medicinal materials. Current studies on glandular trichomes of medicinal plants are mainly focused on morphological identification, with limited research on the compounds secreted by trichomes and secondary metabolic processes.

Summary: The aim of this study was to characterize the structural and histochemical features of two types of glandular trichomes (GTs) found on the leaves and flowers of three Arnica species. The two types of GTs differ in dimensions, coloration intensity, and ultrastructural features of the cells. Phenols, terpenes, sesquiterpene lactones, and polysaccharides are present in all GTs of the studied species, but the amount and composition of these compounds vary between the different types of trichomes and organs.

Summary: The growth of P. australis was significantly reduced in high salinity conditions, as evidenced by decreased plant height, biomass, photosynthesis, and CO2 exchange. While the plant showed tolerance to increasing salinity, its growth and productivity were significantly reduced.

Summary: The study found that different salinities and oil combinations affect mangrove growth, with increased salinity slowing growth and the combination of salinity and oil exacerbating growth reduction. In A. marina, oil absorption and translocation disrupted leaf membranes, ion accumulation, and salt secretion.

Summary: The study compared morphological and physiological responses of Arundo donax and Phragmites australis grown in different soil moisture regimes. Both species showed reduced growth and root length under prolonged complete flooding, but exhibited higher photosynthetic rates in Arundo donax. Phragmites australis demonstrated higher tolerance to waterlogging stress compared to Arundo donax.

Summary: Croton gratissimus (Lavender croton) has three distinct secretory structures, which include lepidote and glandular trichomes, and non-articulated unbranched laticifers. These structures produce secondary metabolites such as alkaloids, phenolic compounds, and lipids, which could potentially be used in traditional medicine.

Summary: This study investigated the addition of yeast to greywater for irrigation purposes and its effects on lettuce and maize. The results showed that yeast treatment improved seed germination and growth in soil conditions, leading to increased biomass and photosynthetic efficiency. Tapwater was more effective than greywater in promoting plant growth. This innovative approach has the potential to enhance water and food security for subsistence farmers.
