Alterations in RNA and protein metabolism in uninoculated half-leaves of cowpea adjacent to tobacco necrosis virus infected halves
Following inoculation of half-leaves of cowpea with tobacco necrosis virus (TNV, R 1 : 1.5 19 : S S : S Fu), two major protein fractions, termed α and β appear in soluble extracts, which are absent from sham-inoculated ...
Similarities in the soluble protein profiles of leaf tissue following either a hypersensitive reaction to virus infection or plasmolysis
Cucumber cotyledons and cowpea leaves both react hypersensitively to tobacco necrosis virus (TNV) infection. The soluble fractions of these tissues, following virus-elicited necrosis, contained apparently novel proteins. ...
Alphanumeric category effects - evidence against the sufficiency of a localization explanation
The experiment utilized a serial choice reaction time (RT) paradigm in which only one alphanumeric stimulus was presented per trial, and the target set consisted of a single identified item. The categorical relationship ...
Vegetation damage during an episode of selenium pollution
Necrotic lesions were observed on the leaves of trees and herbaceous species in the vicinity of a copper refinery. Analysis of leaf samples revealed the presence of excessive concentrations of selenium and copper. The ...
Eradication of cassava mosaic disease from Nigerian cassava clones by meristem-tip culture
Methods previously established for the propagation of cassava plants free from cassava mosaic disease have been applied to Nigerian clones. Meristem tips from diseased plants subjected to heat treatment for not less than ...
