Extract

As reported in the previous paper, 2,4-D (2,4-dichlorophenoxyacetic acid) caused marked changes in the RNA (ribonucleic acid) content of seedling stem tissue, particularly in the microsome fraction. The ribonucleoprotein particles of the microsome fraction participate in protein synthesis and any abnormality in their metabolism could conceivably result in biochemical and physiological disorders leading to the death of the plant.
