Action of Boron on Ethylene Production and Lipoxygenase Activity in Microsomes from Sunflower Cotyledons
Conversion of ACC to ethylene by microsomes isolated from sunflower cotyledons grown in a medium with 50 ppm of boron was strongly increased relative to membranes developed under 10 ppm or without boron, and SHAM, BHT and SOD provoked a high inhibition. A strong increase in ethylene takes place upon incubating ACC and linolenic acid with crude microsomes or with a protein fraction which includes lipoxygenase activity.
