• A Volatile Substance, β-Caryophyllene, from Talaromyces wortmannii Promotes Growth and Tolerance to Diseases on Several Plants

抄録

A plant growth-promoting fungus, Talaromyces wortmannii strain FS2 was isolated from an agricultural field at Okayama Pref. FS2 enhanced seed germination, root elongation and leaf growth of Brassica rapa var perviridis (Komatsuna). Such plant growth-promoting effect was observed in the same sealed chamber where FS2 was cultured on PDA medium separated from seedlings, suggesting effective volatile compound(s). GC‒MS analysis showed that FS2 emitted at least seven terpenoids, of which a volatile was identified as β‒caryophyllene. β‒caryophyllene alone promoted the growth of cucumber, Nicotiana benthamiana and barley. Furthermore β‒caryophyllene increased the yield of cucumber fruits. Interestingly, we found that β‒caryophyllene conditioned these plants to be resistant to respective diseases caused by Colletotrichum orbiculare, Botrytis cinerea or Blumeria graminis f. sp hordei. The findings indicate that β‒caryophyllene has desirable dual features and therefore, it is available to cultivation of many crops.

岡山県総社市の圃場から分離した植物生育促進菌Talaromyces wortmannii FS2が生産するβ-caryophylleneは，コマツナ（アブラナ科）のみならず，キュウリ（ウリ科），タバコ（ナス科）およびオオムギ（イネ科）など広汎な植物に対して，生育促進作用および耐病性増進作用を示したことから，有用な農業資材として利用可能であるものと考察した．
