農学部オープンキャンパス，夏休み自由研究相談，大学院入試，研究室セミナー，輪読

しばらくブログ更新をサボってしまいました．世間では夏休みに入っていますが，大学は今が期末試験期間で夏休みは来週からです．

7/18（土）には農学部でオープンキャンパスが開催されました．長谷川は別の業務で研究室見学には対応できなかったのですが，研究室の学生さんたちが高校生と保護者の方に熱心に説明してくれていたようです．

7/30（木）には茨城県教育委員会主催のいばらき理科教育推進事業で小学生の夏休み科学自由研究相談会が農学部で開催され，長谷川と生物制御化学研究室の大学院生 2 名が自由研究の進め方について助言を行いました．必ずしも専門に近くはない分野についての自由研究も多かったので，私も含め院生も事前の下調べが大変でしたが，勉強にはなりました．

8/1（土）には茨城大学大学院農学研究科修士課程の入学試験が実施されました．今年度から資源生物科学選考では英語の試験は外部試験（TOEIC など）のスコア提出に切り替わりましたので，当日の試験は専門科目と面接だけになりました．

7/17 の研究室セミナーでの文献紹介の担当は四年生の福木さんで，紹介した論文は Xu, S., Nguyen, T., Pomilio, I., Vitale, M.C., and Velu, S.E. (2014). Total synthesis of calothrixins A and B via oxidative radical reaction of cyclohexenone with aminophenanthridinedione. Tetrahedron 70: 5928–5933 でした．

7/24 の研究室セミナーでの文献紹介の担当は四年生の佐山君と化学生態学研究室修士二年生の藤原さんで，紹介した論文はそれぞれ Ditengou, F.A. et al. (2015). Volatile signalling by sesquiterpenes from ectomycorrhizal fungi reprogrammes root architecture. Nat. Commun. 6: 6279 と Qu, Y. et al. (2015). Completion of the seven-step pathway from tabersonine to the anticancer drug precursor vindoline and its assembly in yeast. Proc. Natl. Acad. Sci. USA 112: 6224–6229 でした．
