Compartmental Analysis of Roots in Intact Rapidly-Growing Spergularia Marina and Lactuca Sativa: Partial Characterization of the Symplasms Functional in the Radial Transport of Sodium Ion and Potassium Ion
Techniques of compartmental analysis were adapted to the study of intact roots of rapidly-growing Spergularia marine and Lactuca sativa. Using large numbers of plants short time-courses of uptake and chase, $\sp{42}$K$\sp+$ and $\sp{22}$Na$\sp+$ transport could be resolved, even during a chase following a brief 10 minute labeling period. The use of intact plant systems allowed distinction of that portion of the isotope flux into the root, associated with the ion-conducting symplasms.
