Auxins (plural of auxin /ˈɔːksɪn/) are a class of plant hormones (or plant growth regulators) with some morphogen-like characteristics. Auxins have a cardinal role in coordination of many growth and behavioral processes in the plant's life cycle and are essential for plant body development. Auxins and their role in plant growth were first described by the Dutch biologist Frits Warmolt Went. Kenneth V. Thimann was the first to isolate one of these phytohormones and determine its chemical structure as indole-3-acetic acid (IAA). Went and Thimann co-authored a book on plant hormones, Phytohormones, in 1937.
Explanation:
The fall in pituitary GnRH receptors in female mice after ovariectomy (Ovx) was further decreased (greater than 50%), rather than prevented, by treatment with a GnRH antiserum, despite suppression of the post-gonadectomy increase in serum gonadotrophins, (fmol/pituitary) (intact = 55.3 +/- 2.4; Ovx = 30.1 +/- 2; Ovx + GnRH = 31.6 +/- 2.8), but serum LH was reduced from high post-ovariectomy values (231 +/- 42 ng/ml) to values normal for intact females (24 +/- 2 ng/ml). In contrast
