Presence of specific auxin-binding sites in strawberry fruit (Fragaria ananassa Duch. cv. Ozark Beauty) membranes has been demonstrated. These 1-naphthaleneacetic acid (NAA)-binding sites in the 80,000g to 120,000g fraction of the strawberry fruit membrane were pronase sensitive with an estimated equilibrium dissociation constant for NAA of 1.1 x 10(-6) molar. The minimum concentration of NAA required to stimulate strawberry fruit growth was at least one order of magnitude higher than the… CONTINUE READING
