Journal ArticleDOI
Phenolic antioxidants from the leaves of Corchorus olitorius L.
Keiko Azuma,Masayoshi Nakayama,Masaji Koshioka,Katsunari Ippoushi,Yuichi Yamaguchi,Katsunari Kohata,Yuji Yamauchi,Hidekazu Ito,Hisao Higashio +8 more
TL;DR: Six phenolic antioxidative compounds were identified from the leaves of Corchorus olitorius L. (moroheiya) by NMR and FAB-MS and showed that 5-caffeoylquinic acid was a predominant phenolic antioxidant in C. Olitorius leaves.
Journal ArticleDOI
Precocious Metamorphosis in the Juvenile Hormone–Deficient Mutant of the Silkworm, Bombyx mori
Takaaki Daimon,Toshinori Kozaki,Ryusuke Niwa,Isao Kobayashi,Kenjiro Furuta,Kenjiro Furuta,Toshiki Namiki,Keiro Uchino,Yutaka Banno,Susumu Katsuma,Toshiki Tamura,Kazuei Mita,Hideki Sezutsu,Masayoshi Nakayama,Kyo Itoyama,Toru Shimada,Tetsuro Shinoda +16 more
TL;DR: The identification and characterization of the gene responsible for the dimolting (mod) mutant that undergoes precocious metamorphosis with fewer larval–larval molts is reported, suggesting that authentic epoxidized JHs are not essential in very young larvae of B. mori.
Journal ArticleDOI
Identification of a triterpenoid saponin from a crucifer, Barbarea vulgaris, as a feeding deterrent to the diamondback moth, Plutella xylostella
Tetsuro Shinoda,Tsuneatsu Nagao,Masayoshi Nakayama,Hiroaki Serizawa,Masaji Koshioka,Hikaru Okabe,Akira Kawai +6 more
TL;DR: It is concluded that the unacceptability of B. vulgaris to P. xylostella larvae is primarily due to this saponin, which is extractable with chloroform.
Journal ArticleDOI
Sequence Analysis of the Genome of Carnation (Dianthus caryophyllus L.)
Masafumi Yagi,Shunichi Kosugi,Hideki Hirakawa,Akemi Ohmiya,Koji Tanase,Taro Harada,Kyutaro Kishimoto,Masayoshi Nakayama,Kazuo Ichimura,Takashi Onozaki,Hiroyasu Yamaguchi,Nobuhiro Sasaki,Taira Miyahara,Yuzo Nishizaki,Yoshihiro Ozeki,Noriko Nakamura,Takamasa Suzuki,Yoshikazu Tanaka,Shusei Sato,Kenta Shirasawa,Sachiko Isobe,Yoshinori Miyamura,Akiko Watanabe,Shinobu Nakayama,Yoshie Kishida,Mitsuyo Kohara,Satoshi Tabata +26 more
TL;DR: Intensive characterization of the assigned carnation genes and comparison with those of other plant species revealed characteristic features of the carnation genome, a valuable resource for fundamental and applied research of carnation, especially for breeding new carnation varieties.
Journal ArticleDOI
Generation of blue chrysanthemums by anthocyanin B-ring hydroxylation and glucosylation and its coloration mechanism.
Naonobu Noda,Satoshi Yoshioka,Sanae Kishimoto,Masayoshi Nakayama,Mitsuru Douzono,Yoshikazu Tanaka,Ryutaro Aida +6 more
TL;DR: This work succeeded in generating blue chrysanthemum flowers by introduction of butterfly pea UDP–glucose:anthocyanin 3′,5′-O-glucosyltransferase gene, in addition to the expression of the Canterbury bells F3′5′H.
