TofazzalTahara, Satoshiopen accesshost-specific zoospore attractantcochliophilin AflavonoidsCelosia cristataAmaranthaceae615.81Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 μg/g fresh weight. A new isoflavone, cristatein (5-hydroxy-6-hydroxymethyl-7,2′-dimethoxyisoflavone, 2), and five known flavonoids were also identified.日本農芸化学会Japan Society for Bioscience, Biotechnology, and Agrochemistry2006-10engjournal articleVoRhttp://hdl.handle.net/2115/16011http://www.jstage.jst.go.jp/https://doi.org/10.1271/bbb.60272170310420916-84511347-6947Bioscience Biotechnology and Biochemistry701025672570https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/16011/1/BB%26B70-10.pdfapplication/pdf81.38 KB2006-10
