Reduktaza azotanowa siewek pszenzyta ozimego
Nitrite reductase (NiR) was extracted from seedlings of winter triticale cultivar Moreno
in the form of homogenous protein fraction with molecular weight of about 61 kDa, characterised
by maximum of absorption at 280 and 390 nm. Differences in specific activity of enzyme
isolated from plants cultivated in different conditions (garden soil, Hoagland's diet) suggest that
NiR may be induced by light and nitrate ions presence in arable medium
Zmiany w zawartosci wybranych frakcji bialka izolowanego z siewek pszenzyta jarego poddanego dzialaniu niskiej temperatury
The obtained results indicate that in analysed seed leaves of seedlings of spring triticale
‘Kargo’ cultivar exposed to low temperature occurs a statistically significant decrease in total
protein content, comparing to the control. Similar results were showed by analysing the concentration
of this protein fraction in propagation joints and roots of seedlings of spring triticale
‘Kargo’ (exception propagation joints after 24 h of exposition to low temperature). Simultaneously
a statistically significant increase in soluble protein content in seed leaves was found (exception 12 h of exposition to low temperature) and propagation joints after 12 h of their exposition, comparing to the control plants. Moreover, statistical analysis showed a significant increase in concentration of this protein fraction in roots of seedlings exposed to coldness after 1 and 12 h, comparing to the control
