Certain Enzymatic Activities of Normal and Mosaic Infected Tobacco Plants
The lower leaves of tobacco plants were inoculated with leaf mosaic virus and the activities of oxygenase, peroxidase, catalase, and invertase were followed in leaves of comparable age at intervals of 2 or 3 days over a period of 21 days. The inoculated leaves exhibited a great decrease relative to normal tissue in the activity of oxygenase and peroxidase on the 6th day. Younger leaves showed t...
متن کاملRespiration of Mosaic-infected Tobacco Plants.
There has been reported in the literature a number of attempts to observe in vitro the respiration of virus preparations in an effort to detect direct evidence of a valid metabolic activity. EATON (10) studied manometrically the respiration of cultures of Staphylococcus lysed by bacteriophage and found a detectable amount of oxygen absorption and carbon dioxide production. On the other hand, BR...
متن کاملStudy of Respiration in Healthy and Mosaic-infected Tobacco Plants.
Comparatively little investigatioii has been made into the fundamental iiietabolic processes of plant viruses. BRONFENBRENNER and REICHERT (2, 3, 4) were unable to detect any respiration in either viruses or bacteriophages. The isolation of virus, free from plant cells, and in a condition suitable for such experiments, is obviously very difficult. The effect of virus infections on the metabolis...
متن کامل5'-dephosphorylated 2',5'-adenylate trimer and its analogs. Inhibition of tobacco mosaic virus replication in tobacco mosaic virus-infected leaf discs, protoplasts, and intact tobacco plants.
The effect of the 5'-dephosphorylated 2',5'-adenylate trimer and its 2',5'-trimer core analogs on the inhibition of tobacco mosaic virus (TMV) replication was determined in tobacco leaf discs, protoplasts, and whole tobacco plants, using infectivity tests and enzyme-linked immunosorbent assays. A structure-activity-metabolic stability-toxicity analysis of the 2',5'-adenylate trimer core molecul...
متن کاملCertain effects of benzimidazole on young tobacco plants.
It has been reported that benziazole compounds, of which benzimid'azole is one, are growth regulators (4). The responses of this group of compounds appear to vary somewhat from some of the other growth regullators and bhths according to Klingen)smilth the benzazoles sihoul,d be classified as a slelparate dl'ass of compounds. One of the effects of benzimidazoile is an added uptake o-f potassium ...
