摘要：

Abscisic acid (ABA) fully suppressed the development of the hypersensitive necrosis of potato tuber slices to crude elicitor from Phytophthora infestans and arachidonic acid (AA) if supplied before or up to 6 to 8 h after elicitor treatments. Later application of ABA only reduced the necrotic response. Added to highly purified plasma membrane preparation from tuber tissue, ABA eliminated the AA-induced inhibition of the plasma membrane-bound (K+ + Na+ + Mg2+)ATPase. It is suggested that ABA counteracts AA in the membrane.
