Plant-derived smoke induced activity of amylases, DNA replication and β-tubulin accumulation before radicle protrusion of dormant Avena fatua L. caryopses

Florets of Avena fatua (wild oat) did not germinate at temperatures from 5 to 35 °C, nor did caryopses at 5 and above 15 °C. Smoke–water (SW) was found to partly or substantially induce dormant florets and caryopses to germinate at temperatures from 10 to 25 °C, whereby almost all caryopses germinated at 15 and 20 °C. When florets were dry-stored at 25 °C for 4 months, their ...

Molecular cloning and functional analysis of the second gene encoding glutamate dehydrogenase in triticale

Glutamate dehydrogenase (GDH; EC 1.4.1.2) catalyzes the reductive amination of 2-oxoglutarate with ammonium and the oxidative deamination of glutamate. In some plants species, GDH is a hexamer and can be separated into seven isoenzymes that are composed of two distinct subunits: α and β. The large number of isoenzymes is the reason why GDH functions are still being intensively ...
