Abstract
Diatoms such as Phaeodactylum tricornutum arose through a process termed secondary endosymbiosis, in which red alga-derived plastids are surrounded by a complicated membrane system. Subcellular marker proteins provide defined localizations on the compartmental and even sub-compartmental levels in the complex plastids of diatoms. Here we introduce how to use subcellular marker proteins and in vivo co-localization in the diatom P. tricornutum by presenting a step-by-step method allowing the determination of subcellular localization of proteins in different membranes of the secondary plastid. This chapter describes the materials required and the procedures of transformation and microscopic observation.
