Summary: Pot experiments were conducted to investigate the effects of exogenous MG application on physiological and biochemical characteristics of fragrant rice. The results showed that application of 1 mmol·L-1 MG significantly increased yield and grain 2-AP content. However, high levels of MG (10 mmol·L-1) decreased yield and grain 2-AP content.

Summary: Literature on the effects of exogenous copper application on the grain yield, 2-AP content, and copper content of fragrant rice is limited. This study conducted pot experiments in two seasons and found that foliar copper application had a positive effect on yield and grain 2-AP and Cu content. Moderate copper application (T2 treatment) showed the most desirable outcomes, improving yield, aroma, and enriching the grain copper content of fragrant rice.

Summary: This study found that under foliar zinc application, the 2-acetyl-1-pyrroline (2AP) and zinc contents in aromatic rice were substantially increased, leading to improved 2AP biosynthesis through various pathways such as the activation of the PSCS2 gene. Multiple transcription factors (TFs) were involved in regulating the formation of 2AP in fragrant rice under zinc treatments. Further research is needed to explore the relationship between 2AP biosynthesis pathway genes and TFs in aromatic rice.

Summary: The application of La significantly increased the 2-AP content in aromatic rice, as well as the chlorophyll content, net photosynthetic rate, and total aboveground biomass. Additionally, La treatment resulted in higher grain yield, grain number per panicle, and seed-setting rate of aromatic rice, while decreasing the grain proline and gamma-aminobutyric acid contents.

Summary: The study analyzed 29 samples of fragrant colored rice from Thailand and found that variations in rainfall and altitude in cultivation areas affect the production of volatile compounds and 2AP levels in rice. It was observed that 2AP levels decreased with increasing rainfall and that altitude may influence the production of volatile compounds. Different environmental conditions in cultivation areas can potentially impact volatile compound production during rice growth.

Summary: Peptide-cellulose conjugates designed as optical protease sensors have potential applications in point-of-care (POC) detection. Nanocellulose, with its biocompatibility and high specific surface area, serves as a suitable transducer surface for sensitive detection of dilute biomarkers. Computational models were used to study the relationship between the sensor molecule and the transducer surface, providing insights for enhanced sensor activity design.

Summary: Agricultural waste and residues, such as cotton gin trash and cotton gin motes, were used to prepare lignin-containing cellulose nanofibers with gradient degrees of lignin content. The physical properties of the nanofibers were affected by the lignin content and other components, impacting thermal stability and crystallinity. The degree of polymerization was smaller after processing, with differences based on the source material, resulting in slightly different suspension viscoelastic behavior.
