農学部オープンキャンパス

7/22 は水戸キャンパスで茨城大学全学のオープンキャンパスが開催されましたが,昨日は阿見キャンパスで農学部オープンキャンパスが開催されました.農学部オープンキャンパスでは農学部の各研究室が高校生の見学のために公開されます.生物制御化学研究室は 1 階のあまり人通りが多くない場所にあるので,いつもあまり見学者が多くない傾向にあるのですが,今年は例年よりも見学者が多かった印象でした.後で聞いたところによると,千名以上の来場者があったそうです.これは例年に比べるとかなり多い数です.

「化学と生物」誌にフィトアレキシンについての解説記事が掲載

日本農芸化学会の和文誌「化学と生物」の 2017 年 8 月号に長谷川が執筆した「植物の自己防御物質フィトアレキシンの多様性」という解説記事が掲載されました.

フィトアレキシンの化学構造を明らかにする研究というのは 20 世紀のうちに大体やり尽くされていた感があったのですが,最近イネ科やアブラナ科植物で従来知られていたよりもフィトアレキシンは多様であるということが分かってきました.この解説では 21 世紀に入ってから分かってきた新たなフィトアレキシンについて紹介しています.
