Abstract

V originále

We studied the effect of three factors on the induction of flowering in Arabidopsis thaliana, i.e. vernalization, day length and DNA demethylation. Seven natural late flowering genotypes and 13 late flowering mutants were used in the experiments. The effect of the vernalization and the short day (SD) was uniform in all genotypes used, resulting in shortening (vernalization) or extension of the period before the appearance of the first flower primordia. On the other hand, the effect of the demethylating agent (5-azacytidine [5-azaC]) was not uniform in the genotypes used. In all natural late genotypes (except Lu-1), the shortening of the flowering time (FT) after 5-azaC treatment was observed. On the contrary, only five mutants - dl, pm, M63, M73 and fca-1 - showed a shortening of the FT, while in the majority of the late flowering mutants, no significant response (earlier flowering) was found. The different response to the vernalization and demethylation treatment in late flowering mutants shows the possibility of two different pathways leading to the flowering, both of which are regulated by DNA demethylation. The different response of natural and induced late flowering genotypes after 5-azaC treatment shows that genes that play a role in flower development are of a different nature.
