[The relationship between the conception of the role of histones in the mutagenic process and the combined effect of trichloracetic acid and dimethylsulfate on Arabidopsis].

Separate and combined effect of TChAA and DMS was studied as applied to Arabidopsis of Estland race. When the Arabidopsis seeds were treated with TChAA in M1 separately, stimulation was observed as to certain features. A combined treatment with TChAA + DMS reduces significantly the yield of chlorophyll mutations both as compared to variants of separate treatment and to those of control. On the basis of the data obtained an important role of histones in mutation process is suggested.
