Citrus exocortis viroid (CEVd) infection of tomato cell cultures suppresses the constitutive inhibitor which blocks the conversion of 1‐aminocyclopropane‐1‐carboxylic acid (ACC) to ethylene by tomato microsomes. The inhibitor is associated to microsomal membranes and is also found in the water soluble fraction co‐isolated from the cells. The inhibitory effect is concentration dependent, heat stable and could be removed from solution by dialysis. Its possible relationship with regulation of the viroid‐induced ethylene production is discussed.
