Summary
The relationships among three genetic properties (inhibition by cystine, thermostability, and cystine-requirement) of antigenic type 1 poliovirus were investigated. Partial or complete loss through mutation of the property of being inhibited by cystine was accompanied by changes in the other two properties, indicating that the genetic element(s) which determines inhibition by cystine also determines, at least partially, thermostability and cystine-requirement. Inhibition by cystine and thermostability were found to be closely and positively correlated, suggesting that they are simply different manifestations of a single more basic virus property.
