Ectopic endoreduplication caused by sterol alteration results in serrated petals in Arabidopsis (2005)

Hase, Yoshihiro, Fujioka, Shozo, Yoshida, Shigeo, Sun, Guoqing, Umeda, Masaaki, Tanaka, Atsushi

The Arabidopsis frill1 (frl1) mutant, that has serrated petals and sepals but no other large changes in plant morphology, was studied. The frl1 had a mutation in STEROL METHYLTRANSFERASE 2 and an...

Positional effect of cell inactivation on root gravitropism using heavy-ion microbeams (2002)

Tanaka, Atsushi, Kobayashi, Yasuhiko, Hase, Yoshihiro, Watanabe, Hiroshi

When primary root apical tissues of Arabidopsis thaliana were irradiated by heavy‐ion microbeams with 120 μm diameter, strong inhibition of root elongation and curvature were observed at...

An Ultraviolet-B-Resistant Mutant with Enhanced DNA Repair in Arabidopsis

Tanaka, Atsushi, Sakamoto, Ayako, Ishigaki, Yasuhito, Nikaido, Osamu, Sun, Guakin, Hase, Yoshihiro, ...

An ultraviolet-B (UV-B)-resistant mutant, uvi1 (UV-B insensitive 1), of Arabidopsis was isolated from 1,280 M1 seeds that had been exposed to ion beam irradiation. The fresh weight of uvi1 under...

Disruption of the AtREV3 Gene Causes Hypersensitivity to Ultraviolet B Light and γ-Rays in Arabidopsis: Implication of the Presence of a Translesion Synthesis Mechanism in PlantsW⃞

Sakamoto, Ayako, Lan, Vo Thi Thuong, Hase, Yoshihiro, Shikazono, Naoya, Matsunaga, Tsukasa, Tanaka, Atsushi

To investigate UV light response mechanisms in higher plants, we isolated a UV light–sensitive mutant, rev3-1, in Arabidopsis. The root growth of rev3-1 was inhibited after UV-B irradiation under...
