Prof. SHIONO, Katsuhiro 教授: 塩野克宏

筑波大学地中海・北アフリカ研究センター客員共同研究員 (2011〜現在)。International Society for Plant Low Oxygen Research (ISPLORE)、International Society of Root Research (ISRR)、日本育種学会、根研究学会、日本作物学会、日本植物生理学会、日本沙漠学会各会員。専門は植物生理学と植物分子遺伝学。

My research focuses on interactions between roots and the soil environment, particularly how roots regulate oxygen and mineral transport through apoplastic barriers under flooding. After receiving my PhD in Agriculture from the University of Tsukuba, I conducted postdoctoral work as a JSPS Research Fellow at the University of Tokyo and at the University of Bonn. I have been at Fukui Prefectural University since 2011 and have served as the youngest full professor in my department since 2023. In 2026, I will assume the presidency of the Japanese Society for Root Research. My goal is to elucidate the diverse and plastic functions of root barriers during environmental interactions, contributing to sustainable crop production.

Shiono and Matsuura. (June 6, 2024, Vol. 133, Issue 7,6, Pages 931-940). The cover image shows an artificially induced apoplastic barrier at the hypodermis/exodermis in the outer part of roots (OPRs) of barley by applying abscisic acid (ABA). An apoplastic tracer (periodic acid), visualized as purple, was blocked at the outside of the hypodermis/exodermis under aerated conditions with ABA application. Most dryland crops, including barley, do not form a root apoplastic barrier in the OPRs. In this issue, Shiono and Matsuura demonstrate that apoplastic transport barriers in the OPRs can be induced in such crops by exogenous ABA applications.

塩野・平 (2020, Vol. 55, No. 2, Pages 84-91). ムラサキツユクサの葉におけるアブシシン酸の分布イメージ。乾燥ストレスによりアブシシン酸が気孔に蓄積することはよく知られた現象である。しかし、アブシシン酸分子そのものを、ラベル化や形質転換することなく、直接的に局在を同定することはできなかった。生体上の分子の局在を高空間分解能に検出できる「質量分析イメージング」はアブシシン酸を含む複数の植物ホルモンの同時イメージングを実現する手法として展開が期待される。

Shiono et al. (September 6, 2017, Vol. 65, Issue 35, Pages 7599-7826). An understanding of the dynamics of plant hormones is not only very interesting for fundamental science but also useful for agriculture and commerce. In this study, we revealed the detailed localization of cytokinin and abscisic acid in roots of Oryza sativa using mass spectrometry imaging.

Shiono et al. (January 2011, Vol. 107, Issue 1, Pages 89–99). The inset cover image shows roots of rice with suberin lamellae visualized by fluorescence before (left) or after (right) forming a barrier to radial oxygen loss in response to non-aerated conditions. The formation of the barrier enhances internal O2 diffusion to the root apex, and its induction occurs before histochemically detectable changes in putative suberin and lignin deposits can be seen. See Shiono et al. (pp. 89-99).

Katsuhiro Shiono, Masato Ejiri, Yuto Sawazaki, Yuka Egishi, Tomonori Tsunoda. (Plant Physiology, In Press). Low nitrate concentrations, which occur after molecular oxygen is consumed in waterlogged soils, are an environmental trigger for forming the root barrier to radial oxygen loss in rice roots.
