Tobacco processing practices of humidifying rooms with mist and using steam to soften cured leaf, raise relative humidity (r.h.) and temperature in the rooms during February to March, creating conditions suitable for Liposcelis entomophila multiplication. High r.h. values and high temperatures in these buildings corresponded with the annual peak in booklice numbers. The number of booklice trapp...

A small satellite RNA of tobacco ringspot virus replicates in tissues infected with tobacco ringspot virus and accumulates in virus capsids, forming virus-like particles. Previous research showed that multimeric forms of this satellite RNA have tandem repeats of the "monomeric" satellite RNA sequence of 359 or 360 nucleotide residues. The multimeric RNAs undergo autolytic processing at a specif...

Nornicotine is a secondary tobacco alkaloid that is produced by the N-demethylation of nicotine. Nornicotine production and accumulation in tobacco are undesirable because nornicotine serves as the precursor in the synthesis of the well characterized carcinogen N'-nitrosonornicotine during the curing and processing of tobacco. Although nornicotine is typically a minor alkaloid in tobacco plants...
