Changes in the leaf polypeptide patterns of wheat flag leaves spraying with non-purine cytokinins.
The changes in the polypeptide patterns of soluble proteins of wheat flag leaves after treatment with two synthetic cytokinin-like substances 3-CP-2-PU [1-(3-chlorophenyl)-3-(2-pyridyl)urea] and 3-CP-4-MPU [1-(3-chlorophenyl)-3-(4-methyl-2-pyridyl)urea] was studied. Both compounds increased differentially in quantity and composition most individual polypeptides identified compared to the non-treated leaves. While 3-CP-2-PU increased only the polypeptide quantity, 3-CP-4-MPU led to the appearance of new polypeptide with Mw of 51 kDa.
