Plasmatubules: an alternative to transfer cells?

abstract：:α-Galactosidase II(2) (MW ∼ 43 390) from resting Vicia faba L. seeds had been shown to possess D-glucose/D-mannose-specific lectin activity. Inhibition studies with monosaccharides and an examination of the effects of heat and pH on the catalytic and lectin activities of the enzyme indicate that the enzyme substrate a...

abstract：:Hexokinase (HXK) is a dual-function enzyme that both phosphorylates hexose to form hexose 6-phosphate and plays an important role in sugar sensing and signaling. To investigate the roles of hexokinases in rice growth and development, we analyzed rice sequence databases and isolated ten rice hexokinase cDNAs, OsHXK1 (O...
