White Light Enhances Adhesive Strength Between Epidermal and Inner Tissues of Pea Epicotyls via Accumulation of Cell Wall‐Bound p ‐Coumaric Acid

Yuma Shimizu, Kazuyuki Wakabayashi, Kensuke Miyamoto, Kouichi Soga

The epidermal and inner tissues of stem organs adhere via the cell wall, and the adhesion of both tissues is involved in the structural integrity of the stem. We have developed a method to quantitatively measure adhesive strength between these tissues. In …

Measurement of adhesive strength between the epidermal and inner tissues of plant stems using a tensile tester.

Kazuyuki Wakabayashi, Kensuke Miyamoto, Kouichi Soga

BackgroundThe plant stem is composed of epidermal and inner tissues that are under tension and compression, respectively. Therefore, the adhesion of both tissues is considered to be involved in the structural integrity of the stem. However, the role of tissue adhesion in …

Mechanisms Involved in Cell Wall Remodeling in Etiolated Rice Shoots Grown Under Osmotic Stress

Kazuyuki Wakabayashi, Motomi Shibatsugu, Takayuki Hattori, Kouichi Soga et autres

Osmotic stress impacts the cell wall properties in plants. This study aimed to elucidate the mechanisms involved in cell wall remodeling in etiolated (dark-grown) rice (Oryza sativa L.) shoots grown under polyethylene glycol (PEG)-induced osmotic stress conditions. Shoot growth was inhibited by …

Hypocotyls of Arabidopsis hmg mutants have an altered growth response to hypergravity

Tomoko Koizumi, Kouichi Soga, Kazuyuki Wakabayashi, Masashi Suzuki et autres

3-Hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyzes the rate-limiting step of mevalonate pathway for the biosynthesis of isoprenoids, such as sterols. To clarify the role of membrane sterols in plant response to the gravitational acceleration, we examined the growth behavior and cell wall properties of …

Effects of hypergravity in a centrifuge and simulated microgravity on a horizontal clinostat on tuber formation in single-nodal stem segments from potato (Solanum tuberosum L.) sprouts

Yuto Saeki, Kazuyuki Wakabayashi, Takayuki Hoson, Haruka Sasaki et autres

Tuber formation in potato (Solanum tuberosum L.) under hypergravity conditions in a centrifuge and simulated microgravity (μG) conditions on a horizontal clinostat was studied using in vitro culture of single-nodal stem segments prepared from sprouting tuber shoots. Hypergravity conditions at 100 G …

Suppression of bolting in the Arabidopsis hmg1 mutant under microgravity conditions in space – Possible involvement of lipid rafts

Takayuki Hoson, Kouichi Soga, Kazuyuki Wakabayashi, Rainer Hedrich et autres

3-Hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyzes the rate-limiting step of the mevalonate pathway for biosynthesis of isoprenoids, such as sterols. An Arabidopsis T-DNA insertion mutant for HMGR1 (hmg1) produced roots, hypocotyls, rosette leaves, and inflorescences after germination at on-orbit 1 g in the Resist …
