The process of spraying water and flavorings on dry tobacco is an important factor in the industrial environment and product quality. Tobacco as a complex porous fiber material, the interfacial transfer process of water is complex. In this study, machine learning and image recognition techniques were utilized to quickly obtain the structural parameters of the tobacco surface and construct a cellular structure model of the tobacco surface.

Background: Basic leucine zipper (bZIP) protein is a plant-specific transcription factor involved in various biological processes, including light signaling, seed maturation, flower development, cell elongation, seed accumulation protein, and abiotic and biological stress responses. However, little is known about the pea bZIP family.

Results: In this study, we identified 87 bZIP genes in pea, named PsbZIP1 ~ PsbZIP87, via homology analysis using Arabidopsis.

Background: Amber-like compounds form in tobacco (Nicotiana tabacum) during leaf curing and impact aromatic quality. In particular, cis-abienol, a polycyclic labdane-related diterpenoid, is of research interest as a precursor of these compounds. Glandular trichome cells specifically express copalyl diphosphate synthase (NtCPS2) at high levels in tobacco, which, together with NtABS, are major regulators of cis-abienol biosynthesis in tobacco.

Article Synopsis
  • The text discusses a new optofluidic sensor that uses a liquid-filled fiber structure to detect changes in the refractive index (RI) with high sensitivity.
  • This sensor is created by using a seven-hole Teflon-cladding fiber, which allows liquid to flow through its air hole channels, forming a seven-liquid-core fiber (SLCF) that guides light through total internal reflection.
  • The light coupling between the central and outer cores of the SLCF is influenced by the wavelength, leading to a filter spectrum that changes based on the liquid's RI, achieving an impressive sensitivity of 25,300 nm/RIU around an RI of 1.333.

A novel infrared-assisted extraction coupled to headspace solid-phase microextraction followed by gas chromatography with mass spectrometry method has been developed for the rapid determination of the volatile components in tobacco. The optimal extraction conditions for maximizing the extraction efficiency were as follows: 65 μm polydimethylsiloxane-divinylbenzene fiber, extraction time of 20 min, infrared power of 175 W, and distance between the infrared lamp and the headspace vial of 2 cm. Under the optimum conditions, 50 components were found to exist in all ten tobacco samples from different geographical origins.

Reconstituted tobacco sheet process has been developed to treat and reuse tobacco wastes in the industry. During this process, microorganisms in original and concentrated tobacco waste extract (TWE) might play important roles in the final quality of the reconstituted tobacco. However, microbial communities in TWE remain largely unknown.

Oxidative stress caused by dopamine (DA) may play an important role in the pathogenesis of Parkinson's disease (PD). (+/-) Isoborneol is a monoterpenoid alcohol present in the essential oils of numerous medicinal plants and is a known antioxidant. In this study, we investigated the neuroprotective effect of isoborneol against 6-hydroxydopamine (6-OHDA)-induced cell death in human neuroblastoma SH-SY5Y cells.
