The marked effects of ethylene on pea stem growth have been investigated. Low temperature mid colchicine. both known microtubule depolymerization agents, reverse the effects of ethylene in straight growth tests. Low temperature (6 C) also profoundly reduces the effects of the gas in terms of swelling, hook curvature, and horizontal nutation. Electron microscopy shows that microtubules are reoriented after treatment with ethylene for as little as 12 hours. The findings indicate that some of the ethylene responses may be due to a stabilizing effect on microtubules in plant cells.
