Plant Min protein sits tight and rescues E. coli

... E. coli MinC, and that AtMinD bound EcMinC in these puncta, This is another remarkable finding because while Arabidopsis (and other plants) encode plastid homologs of bacterial MinD and MinE, MinC is either absent or has diverged beyond recognition.

Solar-powered sea-slugs live like plants, prof says

...nhart. "The critical thing is the plastids come from the alga, but the slug nucleus contains at least one, and probably more of the genes required for plastid functioning," he adds. "The slug needs the alga to mature and complete its life cycle," Manhart says. "It is totally dependent on the alga to survi...
