Light-emitting plants (LEPs) provides light in areas without electricity. The phosphorescent compound was used as a lighting material for LEP development. However, using the phosphorescent compound for LEPs development required optimization and phytotoxicity evaluation. Strontium aluminate (SrAl2O4) is a phosphorescent compound that can glow for a long time and is easily recharged by visible light. In this study, using SrAl2O4 to develop LEPs was evaluated. Additionally, plant stress under SrAl2O4 was investigated. Metabolomic analysis can explain the possible mechanism of plants’ stress under SrAl2O4. After, injecting 3 mL of 5 % (w/v) SrAl2O4 products 1, 2, and 3 into the stem of Ipomoea aquatica, the result showed that SrAl2O4 products 2 and 3 caused oxidative stress. The metabolomic analysis also indicated that I. aquatica responded to SrAl2O4 product 1 by increasing pipecolic acid and salicylic acid, while I. aquatica injected with SrAl2O4 products 2 and 3 showed a decrease in salicylic acid around 0.005 and 0.061-fold, respectively, compared to control plants. and an excess accumulation of MDA around 10.00–12.00 μmol g−1 FW. A 15 % concentration of SrAl2O4 can be used for LEPs development, enabling photoemission 18-fold for 50 min. SrAl2O4 product 1 has the potential to be a material for LEPs.  相似文献

In total, 160 ticks infesting cattle in the northeast region of Thailand were collected and used for molecular investigation. Three tick species—Rhipicephalus microplus Canestrini, Rhipicephalus haemaphysaloides Supino and Haemaphysalis bispinosa Neumann—were identified based on morphology and DNA sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) and 16S ribosomal RNA (16S rRNA). In total, 26 and seven unique haplotypes of the CO1 and 16S rRNA genes, respectively, were recovered. Phylogenetic analysis using the CO1 sequence revealed that the R. microplus from northeastern Thailand were grouped into the previously described clades A and C, whereas the 16S rRNA phylogenetic tree assigned all isolates of R. microplus from Northeast Thailand into the previously described clade B. Clade C of the CO1 phylogenetic tree is a new genetic assemblage recently discovered from India and Malaysia, which has now been detected in our study. The haplotype network also demonstrated that R. microplus is divided into two haplogroups corresponding to the assemblage of the CO1 phylogenetic tree. Our findings strongly support the previous genetic assemblage classification and evidence that R. microplus from Northeast Thailand is a species complex comprising at least two genetic assemblages, i.e., clades A and C. However, further investigation is needed and should involve more comprehensive genetic and morphological analyses and cover a larger part of their distributional range throughout Southeast Asia.
