Characterization and function of wall-bound exo-β-glucanases of Lilium longiflorum pollen tubes
Two exo-β-glucanases (LP-ExoI, 83 kDa and LP-ExoII, 71 kDa) were extracted and partially purified from the cell wall of Lilium longiflorum pollen tubes. Both LP-ExoI and LP-ExoII hydrolyzed laminarin (1,3-β-gluca...

Biosynthesis of pectic galactan by membrane-bound galactosyltransferase from soybean (Glycine max Merr.) seedlings
We investigated the properties of a galactosyltransferase (GalT) that is involved in the synthesis of β-(1→4)-galactan side chains of pectins. A membrane preparation of etiolated 6-day-old soybean (Glycine max Me...

Transient increase in the transcript levels of γ-tubulin complex genes during reorientation of cortical microtubules by gravity in azuki bean (Vigna angularis) epicotyls
By hypergravity treatment, the percentage of cells with transverse microtubules was decreased, while that with longitudinal microtubules was increased in azuki bean (Vigna angularis) epicotyls. The expression of ...

Changes in the transcript levels of microtubule-associated protein MAP65-1 during reorientation of cortical microtubules in azuki bean epicotyls
The relation between orientation of cortical microtubules and the transcript levels of a 65 kDa microtubule-associated protein (VaMAP65-1) was investigated along epicotyls of azuki bean (Vigna angularis) seedling...
