Table I.

Anatomical and molecular characteristics of strains Presence of chloroplasts, stigma, and that of PAB as observed by autofluorescence (PAB autofl.) has been published previously (Lebert and Häder, 1997). PAC and AlPAC genes were detected by PCR (Fig. 5A and B). Strains: E. gracilis wild type (E. w+), E. gracilis mutant strains (1F, 9F, FB), and A. longa wild type (A. w+). +, Presence of a feature; -, absence of a feature.
