AN EFFECT OF AUXINS ON THE HEAT COAGULABILITY OF THE PROTEINS OF GROWING PLANT CELLS

Abstract
Auxins induce a decrease in the heat coagulability of the proteins of growing pea stem cells to which they have been applied. The total protein content is not altered. The effect is produced mainly in the non-particulate phase of the cytoplasm. Auxin analogs which do not prt ote growth are less effective or completely ineffective. The effect is greatly reduced, or not produced at all when the active molecules are added in vitro.
