IOJAP protein is found in all organisms that contain a ribosome of bacterial origin. The majority of studies suggest that IOJAP plays a role in translation, although this has yet to be thoroughly investigated in plants. Using Arabidopsis thaliana, an extensive phenotype characterization of iojap mutants was performed. Many processes of plant growth were slightly impaired at optimal temperature (22˚C) but became severely hindered at low temperature (12˚C and 4˚C). These cold temperature defects manifested in an overall reduction of plant growth as well as variegation, chlorosis, leaf hyponasty, as well as reduced maximum quantum yield (Fv/F …

The chloroplast is the green organelle in the plant cell responsible for harvesting energy from sunlight and converting it into sugars and ATP. Origins of this organelle can be traced back to an endosymbiotic event in which a primitive eukaryotic cell capable of oxidative phosphorylation engulfed a free-living cyanobacterium capable of photosynthetic respiration (1). Immediately following this event the details are not clear, however what is known is that over the course of evolution, the engulfed cyanobacteria relinquished approximately 97% of its protein coding sequences to the host cell nucleus, thus making the newly formed chloroplast reliant on its host …
