オープンキャンパス，研究室セミナー，輪読
7/19（土）に茨城大学農学部オープンキャンパスが開催されました．研究室公開は 9:30-15:00 に行われ，午前中にはまずまずの見学者の方がお見えになりました．高校生の親子連れの見学者の方が多く，中には専門的なことにかなり突っ込んでくるお父さんもいらっしゃいました．研究棟の一階は生物制御化学研究室しかなく，やや寂しい雰囲気なので，例年見学のお客さんが少なめなのですが，今年も午後はあまりお客さんがいませんでした．
7/9 の研究室セミナーでの文献紹介の担当は四年生の渡邉さんで，紹介した論文は Rosseto, R. & Hajdu, J. Synthesis of phospholipids on a glyceric acid scaffold: design and preparation of phospholipase A2 specific substrates. Tetrahedron 70, 3155-3165 (2014) でした．ホスホリパーゼ A2 の活性測定などのプローブとして用いることができる基質アナログの合成研究についての論文です．
7/16 の研究室セミナーでの文献紹介の担当は化学生態学研究室四年生の横山さんで，紹介した論文は Paque, S. et al. AUXIN BINDING PROTEIN1 links cell wall remodeling, auxin signaling, and cell expansion in Arabidopsis. Plant Cell 26, 280-295 (2014) でした．AUXIN BINDING PROTEIN 1 の細胞伸長における機能を細胞壁のリモデリングに着目して解析した論文です．
