Nicotiana tabacum L. (NTL) is an important agricultural and economical crop. Its maturity one of the key factors affecting its quality. Traditionally, discriminated visually by humans, which subjective empirical. In this study, we concentrated on detecting as many compounds possible in NTL leaves from different grades using ultra-performance liquid chromatography ion trap time-of-flight mass sp...

Tobacco (Nicotiana tabacum L.) is an important industrial crop grown in more than one hundred countries worldwide, with high adaptability on a great variety of soils, and under quite diverse climatic conditions. Information regarding the chemical composition tobacco leaves for industry because it generally may exhibit differences among different locations. In this study, five oriental six flue ...

Molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. Human TNF Related Apoptosis Inducing Ligand (TRAIL) as a promising biopharmaceutical candidate has been produced in different expression hosts. However, little attention has been paid to molecular farming of the TRAIL in spite of numerous advantages of plant expression systems. Theref...

Low energies of near-ultraviolet radiation (300-400 nanometers), applied simultaneously with visible radiation to Nicotiana tabacum L. during daily illumination periods, increased levels of chlorogenic acid isomers, total soluble phenolics, alkaloids, and soluble sugars in expanding leaf lamina compared with controls that had near-ultraviolet filtered out. However, total nitrogen concentrations...

Tobacco plants (Nicotiana tabacum L.) were grown on long or short photoperiods followed by 5 minutes of red or far red radiation each day. Plants that received 16-hour photoperiods had a significantly higher concentration of total alkaloids and total phenolics than those that received 8-hour photoperiods. Significantly higher total alkaloid content was found in plants that received red rather t...
