The auxin-binding protein 1 (ABP1) has already been proved to be an extracellular receptor of auxin in single cell systems. Protoplasts of maize coleoptiles respond to auxin with an increase in volume. The 2-naphthaleneacetic acid (2-NAA), an inactive auxin analog, acts as an anti-auxin in protoplast swelling, as it suppresses the effect of indole-3-acetic acid (IAA). Antibodies raised against box a of ABP1 induce protoplast swelling in the absence of auxin. This response is inhibited by pre… CONTINUE READING
