The effect of day length, vernalization and DNA demethylation on the flowering time in Arabidopsis thaliana

Popis výsledku v původním jazyce

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 demethylatingagent (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 mut
