We have previously shown that the 15-amino acid carboxyl-terminal propeptide of probarley lectin is necessary for the proper sorting of this protein to the plant vacuole. A mutant form of the protein lacking the carboxyl-terminal propeptide is secreted. To test whether the carboxyl-terminal propeptide is the vacuole sorting determinant of probarley lectin, we examined in transgenic tobacco the ...

The accumulation of pathogenesis-related proteins (PR) in tobacco leaves has been casually related to pathogen and specific physiological stresses. The known enzymatic function of some of these proteins is potentially antimicrobial. By using antibodies specific to three classes of pathogenesis-related proteins, we examined tobacco plants during their normal growth. The pathogenesis-related prot...

The potential of tobacco waste as a viable source of medicinally important flavonoids like rutin has been investigated. Three flavonoids, apigenin, quercetin and rutin, have been isolated from waste tobacco leaves, and their identities have been confirmed by UV-visible, 1H-NMR and 13C-NMR spectroscopy. By using analytical HPLC, the amount of rutin present in the tobacco leaves, before and after...

Tobacco is one of the major economical crops in agriculture sector. It essential to detect tobacco plants using unmanned aerial vehicle (UAV) images for improved crop yield and plays an important role early treatment plants. The proposed research work carried out three phases: In first phase, we collect from UAV’s apply French Commision Internationale de l'eclairage (CIE) L*a*b colour space mod...
