Abstract: | The effects of wheat germ agglutinin (WGA) and phytohemagglutinin (PHA) at the concentration of 1 mg/l on the rate of cell
division in the root apical meristem of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), rice (Oryza sativa L.), and common bean (Phaseolus vulgaris L.) seedlings were compared. WGA enhanced cell division in the roots of barley and rice approximately similarly as in wheat
roots but did not affect division of meristematic cells in the roots of common bean seedlings. In contrast PGA enhanced mitotic
activity in the root apical meristem of common bean seedlings but did not affect division in the wheat and barley roots. Seedling
treatment with lectins shifted the hormonal balance in them toward accumulation of growth activators (IAA and cytokinins).
The relationship between lectin and hormonal systems in the control of cell division is discussed. |
