Atnoa1 mutant Arabidopsis plants induce compensation mechanisms to reduce the negative effects of the mutation

Popis výsledku v původním jazyce

Alterations in temperature adaptation processes and changes in the content of stress-related compounds, polyamines and salicylic acid were evaluated in Atnoa1 (NO-associated 1) Arabidopsis mutant. The F,IF,T, chlorophyll-a fluorescence induction parameter and the actual quantum yield were significantly lower in the Atnoa1 mutant than in the wild-type. In the wild-type Col-0, the fastest increase in the non-photochemical quenching (NPQ) occurred in plants pre-treated at low temperature (4 degrees C), while the slowest was in those adapted to 30 degrees C. The NPQ showed not only a substantially increased level in the light-adapted state, but also more rapid light induction after the dark-adapted state in the Atnoa1 mutant than in the wild-type. The results of freezing tests indicated that both the wild-type and the mutant had better freezing tolerance after cold hardening, since no significant differences were found between the genotypes.
