“…We therefore propose A. indica as a good herbaceous model for gall development, since it is easy to find in nature and to cultivate in the laboratory, and transgenic methods have been established for related species such as A. annua (Hassani et al, 2023). A. indica produces functional ingredients such as artemisinin and lutein (Komuro et al, 2017;Mannan et al, 2011), and our preliminary data show that Wata galls possess antioxidant activity similar to A. indica leaves, so the gall system of A. indica will be valuable for both basic and applied research in the future. The samples were dehydrated through an ethanol series (50%, 60%, 70%, 80%, 90%, and 99.5%, v/v) and an ethanol-lemosol series (ethanol/lemosol = 100/0, 75/25, 50/50, 25/75, and 0/100) and replaced with wax using Paraplast Plus (Sigma-Aldrich, Japan).…”

Plant galls generated by insects have highly organized structures, providing nutrients and shelter to the insects living within them. Most research on the physiological and molecular mechanisms of gall development has focused on single galls. To understand the diversity of gall development, we examined five galls with different morphologies generated by distinct species of Rhopalomyia (gall midge; Diptera: Cecidomyiidae) on a single host plant of Artemisia indica var. maximowiczii (Asteraceae). Vasculature developed de novo within the galls, indicating active transport of nutrients between galls and the host plant. Each gall had a different pattern of vasculature and lignification, probably due to differences in the site of gall generation and the gall midge species. Transcriptome analysis indicated that photosynthetic and cell wall–related genes were down‐regulated in leaf and stem galls, respectively, compared with control leaf and stem tissues, whereas genes involved in floral organ development were up‐regulated in all types of galls, indicating that transformation from source to sink organs occurs during gall development. Our results help to understand the diversity of galls on a single herbaceous host plant.

This work designed and synthesized the first organic fluorescent sensor for lutein in aqueous solutions based on blue to yellow fluorescence change of thiosemicarbazide‐bridged bis‐tetraphenylene (Bis‐TPE). By condensing monohydroxy tetraphenylene derivatives with p‐phenylene di‐isothiocyanate, Bis‐TPE was produced. A fluorescence spectrophotometer was used to scan the fluorescence emission spectra from 380 to 700 nm with 360 nm as the excitation wavelength. The fluorescence spectra showed that Bis‐TPE exhibited high selective sensing ability for lutein in aqueous medium, and the fluorescence showed red‐shift phenomenon with a limit of detection as low as 0.26 μM for lutein. The sensing mechanism was confirmed by mass spectrometry, infrared, and fluorescence Job's plots based on the 1:1 stoichiometric ratio of double hydrogen bonding. The successful application of Bis‐TPE in sensing test strips means that Bis‐TPE can achieve efficient detection of lutein in complex environments. As a result, an aggregation‐induced luminescence‐based lutein fluorescence sensor was constructed, which exhibited highly selective and sensitive sensing of lutein, and provided a new research idea for the object detection of such structures.
