Identification of a Novel Factor, Vanillyl Benzyl Ether, Which Inhibits Somatic Embryogenesis of Japanese Larch (Larix leptolepis Gordon) (2005)

Umehara, Mikihisa, Ogita, Shinjiro, Sasamoto, Hamako, Koshino, Hiroyuki, Asami, Tadao, Fujioka, Shozo, ...

In contrast to angiosperms, some gymnosperms form well-developed suspensors in somatic embryogenesis. This characteristic makes it easy to study suspensor biology. In cultures with high cell...

Cryptosporiopsis abietinaの産生するクロモン誘導体の化学構造について (2003)

佐藤, 博二, 浅川, 聡子, 大橋, 聡, 越野, 広雪, SATO, Hiroji, ASAKAWA, Satoko, ...

The chromone derivative, 2-[(2'R)-hydroxypropyl]-5-metyl-7-hydroxychromone 1 was isolated from Cryptosporiopsis abietina. The structure was determined as the reversed optical isomer of aloesol by...

The Cyanogenic Glucoside, Prunasin (D-Mandelonitrile-£-D-Glucoside), Is a Novel Inhibitor of DNA Polymerase{beta} (1999)

Mizushina, Yoshiyuki, Takahashi, Naoko, Ogawa, Akitsu, Tsurugaya, Kyoko, Koshino, Hiroyuki, Takemura, Masaharu, ...

A DNA polymerase 0 (pol. 0) inhibitor has been isolated independently from two organisms; a red perilla, Perilla frutescens, and a mugwort, Artemisia vulgaris. These molecules were determined by...

A Diterpene as an Endogenous Signal for the Activation of Defense Responses to Infection with Tobacco mosaic virus and Wounding in Tobacco

Seo, Shigemi, Seto, Hideharu, Koshino, Hiroyuki, Yoshida, Shigeo, Ohashi, Yuko

In pathogen-infected or wounded tobacco plants, the activation of wound-induced protein kinase (WIPK), a tobacco mitogen-activated protein kinase, has been implicated in the defense response....

Gene Encoding the Hydrolase for the Product of the meta-Cleavage Reaction in Testosterone Degradation by Comamonas testosteroni

Horinouchi, Masae, Hayashi, Toshiaki, Koshino, Hiroyuki, Yamamoto, Takako, Kudo, Toshiaki

In a previous study we isolated the meta-cleavage enzyme gene, tesB, that encodes an enzyme that carries out a meta-cleavage reaction in the breakdown of testosterone by Comamonas testeroni TA441 (M....

Identification of 9,17-Dioxo-1,2,3,4,10,19-Hexanorandrostan-5-oic Acid, 4-Hydroxy-2-Oxohexanoic Acid, and 2-Hydroxyhexa-2,4-Dienoic Acid and Related Enzymes Involved in Testosterone Degradation in Comamonas testosteroni TA441

Horinouchi, Masae, Hayashi, Toshiaki, Koshino, Hiroyuki, Kurita, Tomokazu, Kudo, Toshiaki

Comamonas testosteroni TA441 utilizes testosterone via aromatization of the A ring followed by meta-cleavage of the ring. The product of the meta-cleavage reaction,...
