新年度が始まりました．昨年度の学生は修士 1 名が修了し，4 年生 4 名が卒業しました．今年度は卒業生のうち 2 名が大学院に進学して，新 4 年生 4 名が研究室に配属されました．研究室の学生は博士 3 年 1 名，修士 2 年 1 名，修士 1 年 2 名，学部 4 年 4 名の計 8 名で新年度スタートとなりました．
年度初めから幸先の良いことに博士課程学生の堀江清孝君が筆頭著者の論文が 4/11 にアメリカ化学会の英文誌 J. Agric. Food Chem. にアクセプトされました．この論文は新規のイネフィトアレキシンであるファイトカサン F とジテルペン系フィトアレキシン生合成中間体と想定される 2 つの化合物についての報告です．本研究は，堀江君の博士論文研究の一部ですが，卒業・修了生の井上靖乃さん，阪井美紀さん，姚群さん，谷本洋輔君の卒業・修士論文研究を発展させたものです．詳しい内容については別のエントリで後ほど書こうと思います．
