A Transcriptional Activator, AoXlnR, Controls the Expression of Genes Encoding Xylanolytic Enzymes in Aspergillus oryzae
Junichiro Marui,Akimitsu Tanaka,Satoshi Mimura,Leo H. de Graaff,Jaap Visser,Noriyuki Kitamoto,Masashi Kato,Tetsuo Kobayashi,Norihiro Tsukagoshi +8 more
TL;DR: By deletion across the promoter region of the xynF1 gene encoding the major Aspergillus oryzae xylanase, a 53-bp DNA fragment containing the XlnR binding sequence GGCTAAA as well as two similar sequences was shown to confer xylan inducibility on the gene.

Characterization of a tobacco TPK-type K+ channel as a novel tonoplast K+ channel using yeast tonoplasts.
Shin Hamamoto,Junichiro Marui,Ken Matsuoka,Kyohei Higashi,Kazuei Igarashi,Tsuyoshi Nakagawa,Teruo Kuroda,Yasuo Mori,Yoshiyuki Murata,Yoichi Nakanishi,Masayoshi Maeshima,Isamu Yabe,Nobuyuki Uozumi +12 more
TL;DR: Results show that NtTPK1 is a novel tonoplast K+ channel belonging to a different group from the previously characterized vacuolar channels SV, FV, and VK.

Kojic acid biosynthesis in Aspergillus oryzae is regulated by a Zn(II)(2)Cys(6) transcriptional activator and induced by kojic acid at the transcriptional level.
Junichiro Marui,Noriko Yamane,Sumiko Ohashi-Kunihiro,Tomohiro Ando,Yasunobu Terabayashi,Motoaki Sano,Shinichi Ohashi,Eiji Ohshima,Kuniharu Tachibana,Yoshitaka Higa,Marie Nishimura,Hideaki Koike,Masayuki Machida,Masayuki Machida +13 more
TL;DR: A gene encoding the Zn(II)(2)Cys(6) transcriptional factor was determined to be essential for KA production and the transcriptional activation of KA biosynthetic genes, which were triggered by the addition to Aspergillus oryzae.

Transcriptional activator, AoXlnR, mediates cellulose-inductive expression of the xylanolytic and cellulolytic genes in Aspergillus oryzae
TL;DR: AoXlnR was newly found to mediate the cellulose‐inductive expression of the xylanolytic gene as well as the cellulolytic genes in Aspergillus oryzae.

The SskA and SrrA response regulators are implicated in oxidative stress responses of hyphae and asexual spores in the phosphorelay signaling network of Aspergillus nidulans.
Daisuke Hagiwara,Yoshihiro Asano,Junichiro Marui,Kentaro Furukawa,Kyoko Kanamaru,Masashi Kato,Keietsu Abe,Tetsuo Kobayashi,Takafumi Yamashino,Takeshi Mizuno +9 more
TL;DR: When examined these mutant strains under various conditions stressful for hyphal growth and asexual spore development, two of them showed a marked phenotype of hypersensitivity to oxidative stresses, indicative of the physiological importance of the His-Asp phosphorelay signaling network involving the SskA and SrrA response regulators.
