| Outline of Final Research Achievements |
In Arabidopsis, ribosomal protein genes are consisted of two to four paralogs, and, in most of the cases, the difference in the encoded amino acid sequences is one to several percent from each other. The possibility that these differences are plants’ strategy to cope with the changing environmental conditions was explored by analyzing ribosome stalling under specific condition as well as analysis of published transcriptome data. The latter analysis showed that expression levels of paralogous genes change depending on the stress conditions. Whether the paralogous subunit proteins are functioning in the ribosome particles is yet to be studied.
