丹羽杯ソフトボール大会，研究室セミナー，5/23 〜 6/17 の輪読

しばらくブログ更新をサボってしまいました．

6/4（土）には学科の研究室対抗ソフトボール大会丹羽杯が開催されました．研究室対抗と言っても，最近は研究室が教員一人一人の単位で運営されていて，研究室単位ではチームが成り立たなくなってしまっているので，チームを作るために適当な合同チームで実施されています．生物制御化学研究室も一研と二研は別のチームに入って参加しています．今年は一研の入っているチームが優勝，二研の入っているチームが準優勝と大変優秀な成績だったようです．

5/26 の研究室セミナーの文献紹介の担当は修士 1 年の北村君で，紹介した論文は Markovič, M., Lopatka, P., Koóš, P., and Gracza, T. (2015). First total synthesis of natural andytriol and a biomimetic approach to varioxiranes. Tetrahedron 71: 8407–8415 でした．6/2 は修士 1 年の勝間田君の担当で，紹介した論文は Piotrowski, J.S. et al. (2015). Plant-derived antifungal agent poacic acid targets β-1,3-glucan. Proc. Natl. Acad. Sci. USA 112: E1490–E1497 でした．6/9 は化学生態学研究室修士 2 年の横山さんの担当で，紹介した論文は Katz, E. et al. (2015). The glucosinolate breakdown product indole-3-carbinol acts as an auxin antagonist in roots of Arabidopsis thaliana. Plant J. 82: 547–555 でした．
