Effect of exogenous thiamin on the activity of cell nuclear RNA polymerases and biomass yield of barley plants



Effect of exogenous thiamin on the activity of cell nuclear RNA polymerases and biomass yield of barley plants



Lietuvos TSR Aukstuju Mokyklu Mokslo Darbai, Biologija ( 28): 112-121



Grains of Ida were soaked in various thiamin solutions (2-50 mg/litre). Nuclear RNA polymerase I and II activity in above-ground parts of 7-day-old seedlings and of plants at the tillering stage was enhanced by 11-378% in treated plants compared to an untreated control, while at later developmental stages it was suppressed by 6-45%. There was a direct relationship between activity of nuclear RNA polymerase and biomass yield at various developmental stages.
