本日で茨城大学は仕事納めで，研究室もとりあえずお休みです．新年は 1/4 から再開予定です．
修士課程二年生の井上靖乃さんが日本農芸化学会の英文誌 Bioscience, Biotechnology, and Biochemistry 誌に投稿していた論文が 12/25 にめでたくアクセプトされました．この論文は井上さんの卒業論文・修士論文研究の成果ですが，その基盤となるデータは卒業・修了生の阪井美紀さん，姚群さん，谷本洋輔君の卒論・修論の研究で得られたものです．詳しい内容については論文がウェブ公開されてから書きたいと思いますが，久しぶりのイネの新しいフィトアレキシンの発見を報告した論文です．
今週の輪読では下記の論文を取り上げました．これで今年の輪読は終了で，新年は 1/7 から再開予定です．

Wiwik さん帰国，今週の輪読
3 ヶ月間研究室で実験に取り組んでいたインドネシアのウダヤナ大学から来た Wiwik さんが，今日で研究を終えて明日インドネシアに帰国します．残念ながら，研究は試料の難しさもあってなかなか思うようには進みませんでした．帰国してからの研究がうまく進むことを祈ります．
