Nr Activity

Tobacco nitrate reductase (NR) produced in yeast retains cytochrome c reductase activity, but not NR activity. Biochemical data suggest that the haem and FAD domains are functional, and that the molybdenum cofactor (MoCo) domain is inactive owing to the absence of MoCo in yeast. The native form of the produced NR is dimeric. Thus MoCo is not involved in NR dimerization in higher plants, contrary to current assumptions.

Oxidative Stress Indicators

Arsenite [As(III)] is a highly toxic chemical to all organisms. Previously, we reported that the overexpression of NtCyc07 enhanced As(III) tolerance and reduced As(III) accumulation in yeast (Saccharomyces cerevisiae) and tobacco (Nicotiana tabacum). To understand a mechanism for higher As(III) tolerance and lower As(III) accumulation in NtCyc07-overexpressing tobacco, we examined the expression levels of various putative As(III) transporters (aquaporin). The expressions of putative As(III) exporter NIP1;1, PIP1;1, 1;5, 2;1, 2;2, and 2;7 were enhanced, while the expressions of putative As(III) importer NIP3;1, 4;1, and XIP2;1 were decreased, contributing to the reduced accumulation of As(III) in NtCyc07-overexpressing tobacco. In addition, the levels of oxidative stress indicators (H2O2, superoxide and malondialdehyde) were lower, and the activities of antioxidant enzymes (catalase, superoxide dismutase and glutathione reductase) were higher in NtCyc07-tobacco than in the control tobacco. This suggests that the lower oxidative stress in transgenic tobacco may be attributed to the higher activities of antioxidant enzymes and lower As(III) levels. Taken together, the overexpression of NtCyc07 enhances As(III) tolerance by reducing As(III) accumulation through modulation of expressions of putative As(III) transporters in tobacco.

Tobacco mosaic virus (TMV) infection has been studied in several investigations of Nicotiana tabacum leaf tissue. Earlier studies have suggested that TMV infection does not have precise infective selectivity vs. specific types of tissues. Also, such tissue conditions as vein banding, vein clearing, liquification and suberization may result from causes other than direct TMV infection. At the present time, it is thought that the plasmodesmata, ectodesmata and perhaps the plasmodesmata of the basal septum may represent the actual or more precise sites of TMV infection.TMV infection has been implicated in elevated levels of oxidative metabolism; also, TMV infection may have a major role in host resistance vs. concentration levels of phenolic-type enzymes. Therefore, enzymes such as polyphenol oxidase, peroxidase and phenylalamine ammonia-lyase may show an increase in activity in response to TMV infection. It has been reported that TMV infection may cause a decrease in o-dihydric phenols (chlorogenic acid) in some tissues.
