Chloroplasts from 3 Different Genotypes of <i>Arabidopsis thaliana</i>

Caption

This shows chloroplasts from three different genotypes of Arabidopsis thaliana: a healthy wild-type chloroplast with an extensive thylakoid membrane network (center); a chloroplast from a ppi1 mutant plant which lacks the atToc33 protein (bottom); and a ppi1 plant with a second mutation in the SP1 gene (top). Chloroplasts from the sp1 ppi1 double mutant are much more developed than ppi1 single-mutant chloroplasts as the effects of atToc33's absence have been substantially suppressed by the absence of SP1.
