Article Abstract
This study investigated the aroma-releasing mechanism of rose during the scenting process with black tea. By quantitative descriptive analysis of sensory evaluations, it was found that 20-h scenting optimized the floral fragrance accumulation while minimizing the undesirable green odors. Meanwhile, neryl alcohol, citronellol, rose oxide, geraniol, linalool, phenethyl alcohol, neryl acetate, citronellyl acetate, eugenol, methyleugenol, and phenethyl acetate were identified as the dominant contributors to the aroma profiles of rose black tea and rose petals. Notably, methylerythritol phosphate (MEP) metabolism, specifically enzymes such as 1-deoxy-D-xylulose-5-phosphate synthase (DXS), alcohol acyltransferase (AAT), and linalool synthase (LIS), and phenylalanine metabolism are the crucial pathways for the key aroma volatile synthesis. Interestingly, we found the introduction of black tea was able to early stimulate those enzymes and then activate the related metabolic pathways to facilitate the emission of rose aromatics, which were subsequently adsorbed by the tea base, yielding a floral-rich rose black tea.

The cerambycid beetles are important components in the terrestrial ecosystem as they play a dual role in both degrading dying trees and killing healthy plants. The factors including human activity, habitat contraction, climate changes and pesticide use have been shaping the adaptation of beetles to host plants and the environment. As suggested in research on the functions of beetles' olfactory proteins, odorant binding proteins (OBPs) have been found to be involved in insecticide resistance other than chemoreception.

Soil may contain certain concentrations of the natural radionuclide K as well as the artificial radionuclide Cs, which can accumulate in the edible parts of plants. This can lead to an exceedance of the ingestion dose. In this study, measurements of K and Cs were conducted for 144 food samples (including fruit, tea, cereals, beans, salt, and sugar) using gamma spectrometry.

YAP/TAZ are transcriptional co-activators that pair with transcription factor TEA/ATTS domains (TEADs) for modulating the Hippo pathway. Previous works propose the potential role of YAP/TAZ phase separation for transcriptional activation, yet the biomolecular basis of endogenous YAP/TAZ-TEAD condensates remains unclear. Here, we dissect their endogenous morphology, revealing that YAP/TAZ are client proteins recruited to TEAD condensates in various human cell lines.

Chemical investigation of the twigs and leaves of Euphorbia tirucalli afforded six undescribed tigliane glycosides, tirucalosides A-F (1-6), together with 12 known diterpenoids (7-18). Compound 1 represents a rare carbon skeleton bearing a 5/7/5/4-fused ring system, while compound 6 contains an unusual seco-glucoside substitution. Their structures were determined by a combination of an extensive spectroscopic analysis and acid hydrolysis experiment.
