Abstract: | The effect of synthetic analogs of phytohormones and red light absorbed by phytochrome on the phospholipase D activity (PLD) was studied in oat (Avena sativa L.) seedlings. ABA manifested a short-term stimulating effect on PLD activity in the green seedlings and inhibited phospholipase activity in the etiolated plants. Kinetin inhibited enzyme activity in the etiolated seedlings and did not affect its activity in light. GA did not markedly affect PLD activity in the etiolated plants and activated this enzyme in the green seedlings. Finally, IAA did not affect the enzyme activity. The relationship of the regulatory effects of phytohormones and light on PLD activity is discussed. |
