Plants are an attractive host system for pharmaceutical protein production. Many therapeutic proteins have been produced and scaled up in plants at a low cost compared to the conventional microbial and animal-based systems. The main technical challenge during this process is to produce sufficient levels of recombinant proteins in plants. Low yield is generally caused by proteolytic degradation ...

Tobacco (Nicotiana tabacum cv. Xanthi nc) resistant to Tobacco mosaic virus (TMV) displays a hypersensitive response (HR) following virus infection, characterized by localized necrotic lesions around infection sites at ambient temperatures (e.g. 20°C). We have demonstrated that application of chemical compounds that generate reactive oxygen species (ROS), such as the riboflavin/methionine and g...

A method to establish two experimental corky ringspot disease (CRS) plots that had no prior CRS history is described. CRS is a serious disease of potato in the Pacific Northwest caused by tobacco rattle virus (TRV) and transmitted primarily by Paratrichodorus allius. 'Samsun NN' tobacco seedlings were inoculated with viruliferous P. allius in the greenhouse before they were transplanted into th...

BACKGROUND: Nicotiana tobacco contains large amounts of alkaloid nicotine. Tobacco plant is used for smoking and causes many health problems since it is high in nicotine which is one of the widely-recognized toxic compounds with serious side effects for different body organs. Reducing nicotine content of this plant is a way to reduce its health hazards in cigarette smokers. Utilizing the new ...

Abstract The BP neural network model used in data classification can change the traditional manual classification, which has disadvantages of low efficiency and subjective interference. According to principle BP, this paper determines relevant parameters structure, establishes an optimized BP. is analyze chemical composition tobacco leaves determine grade leaves. Experiments show that better re...

Abstract Tobacco production in Indonesia continues to increase along with the number of requests tobacco industry due shift consumer tastes from smoking kretek cigarettes white. Virginia’s domestic has not been able cover needs industry, so part this is fulfilled imported tobacco. In terms cultivation, emergence flowers resulted stunted growth and decreased quality Increasing can be done by app...

Abstract The composition and content of aroma substances in flue-cured tobacco ( Nicotiana tabacum L.) will affect the quality tobacco. To investigate correlation between various K326 before after flue-curing, their impact on diversity, this study employed middle leaves KRK26 as test materials. Samples were collected both flue-curing for untargeted metabolomics analysis. results showed that 584...
