Abstract
In order to clarify the effect of protein synthesis inhibition on anoxiatolerance, lettuce (Lactuca sativa L.) seedlings weresubjected to anoxic stress in the presence of cycloheximide (CHM). Atconcentrations greater than 3 , CHM decreased thesurvivability of the roots and the survivability decreased with increasing CHMdoses. At 100 CHM, the survivability was 41% of thatof non-CHM-treated seedlings. Alcohol dehydrogenase (EC 1.1.1.1) activity andATP concentration in the roots of the seedlings were also decreased by CHM,which may be one of the causes of the reduced anoxia tolerance of the seedlings.
