| Outline of Final Research Achievements |
Desiccation-tolerant leafy gametophyte of the red alga Pyropia yezoensis is commercially important marine crop for the major source of dried Nori (Nori sheets). We recently found that dried Nori contains abundant chloroplast ribosomes as 70S-type particles. In this study, we explored proteinaceous factors, which may confer desiccation-tolerance and heat-stability, by means of proteomic approaches. Consequently, we found novel LEA-like proteins that are likely localized in the chloroplast stroma. We also suggest that the protein composition of P. yezoensis chloroplast ribosome and its translation factors resembles that of mesophilic bacteria (e.g., E. coli).
