title: [Effect of 12-hydroxy-9(Z)-dodecenoic acid on growth and cell division in pea roots].
abstract: It is known that potential bioregulators may be present among lipoxygenase oxidation products. A possibility of mitotic cycle regulation by 12-hydroxy-9(Z)-dodecenic acid (12-HDA) and also its influence on the growing function (seed germination, root and epicotyl growth) have been studied. It has been determined that 12-HDA activity is directed to the strengthening of growing function which allowed to suppose that oxylipin is capable of regulating cell division. 12-HDA participation in the mitotic cycle regulation were determined by the originally developed test system using simultaneously light microscopy. The concentration and temporal dependencies of cell division were studied under the influence of 12-HDA. The raise of mitosis (up to 17.5 times) has been registered in comparison with the control variant by the least concentration of 12-HDA (10(-9) M) up to the 4th h of influence, confirming oxypilin participation in mitotic cycle regulation.
