Figure 2. Putative mechanism for the evolution of ARId (anhydrobiosis-related gene island) in the P. vanderplanki genome.
ARIds are genomic regions containing clusters of duplicated genes that are transcriptionally active during anhydrobiosis. (a) A gene of foreign origin (for example, LEA protein) is incorporated into P. vanderplanki genome by HGT and undergoes extensive duplications and shuffling. (b) A pre-existing P. vanderplanki gene originally not involved in anhydrobiosis and originating from another region of P. vanderplanki genome was inserted to a new locus by intragenomic duplication (IGD) and undergoes extensive duplications and shuffling to acquire or improve a specific function for desiccation tolerance. All the genes in the ARIds from both a,b become highly upregulated during anhydrobiosis (red arrows).

Environment Minister Nobuteru Ishihara in OIST’s Golden Book

On June 29 and 30, the International Conference on Climate Change and Coral Reef Conservation (organized by the Ministry of Environment and Okinawa Prefecture with the support of OIST and the University of the Ryukyus) was held at the OIST campus. Environment Minister Nobuteru Ishihara was guided around the OIST campus and visited the Energy Materials and Surface Sciences Unit (led by Prof. Yabing Qi), in which new solar energy materials are being developed. He also stopped by at the Marine Genomics Unit (led by Prof. Noriyuki Satoh), which conducts genome research of marine organisms such as corals.
