Several Convolvulaceae species harbor heritable fungal endophytes from which alkaloids are translocated to reproductive tissues of the plant host. Evidence for the distribution and ecological role of these fungal alkaloids, however, is lacking or incomplete for many host species and growth forms. Here we report on the identity of the fungal endophytes and quantities of alkaloids present in the leaves and seeds of the arborescent morning glory, Ipomoea murucoides (Convolvulaceae).

Although solar steam generation is effective in evaporating water and seawater under solar light irradiation, it is ineffective in purifying wastewater and seawater with organic pollutants. Herein, a morning glory-shaped water purification device with a dry chimney (pistil) is designed for simultaneous solar-thermal evaporation of water and catalytic degradation of organic pollutants therein, which is fabricated by decorating Au/CoFeO/carbon nanotube functional components on a hydrophilic and porous bamboo fabric substrate. Au and CoFeO are capable of forming Mott-Schottky heterostructures to create a stable built-in electric field and promote the separation of electron-hole pairs, thereby facilitating the activation of potassium peroxymonosulfate to generate reactive oxygen species and achieving a high catalytic degradation rate constant of 0.

The metabolic diversity of plants, comprising over a million different metabolites across the plant kingdom, harbors enormous potential for pharmaceutical and biotechnological applications. Resin glycoside (RG) acylsugars from the Convolvulaceae are of interest due to their medicinal and agricultural potential. However, understanding the biological relevance of RGs is challenging as they exhibit a high lineage-specific structural diversity.

The present study aims to evaluate and compare some of the main indicators characterizing Bulgarian linden honey depending on the geographical origin. A total of 18 samples were collected from the six regions of Bulgaria, with 3 samples from each region taken from different producers during the 2023 harvest. The physicochemical indicators: hydroxymethylfurfural content, diastase activity, pH, color, water content and electrical conductivity, as well as organoleptic and pollen characteristics, were analyzed.
