The effect of indole-3-acetic acid on coleoptile extension growth in the absence of protein synthesis

摘要

In wheat coleoptile sections cycloheximide inhibited over 90 of14C-leucine incorporation into protein within 10 minutes of its application. Even after 2-hour pretreatments with cycloheximide, IAA stimulated extension, suggesting that its growth-promoting action did not directly involve protein synthesis.
