A cytoductant was considered to have GFP foci if more than 10% of the fluorescent cells had aggregates. Three samples of ~100 cells were assayed for each cytoductant. [PSI+] induction was scored as an increase of Ade+ in response to overexpression of SUP35 (Fig. 5). “N” and “C” indicate N- and C-terminal deletions, respectively.
Transmission of low [PIN+] could not be scored by [PSI+] induction in the recipient strain background
