dissertation supervisor problems - Many plant-associated bacteria have the ability to produce the plant growth regulator indoleacetic acid (IAA) (5, 9, 25, 33). IAA is involved in diseases caused by gall- and knot-forming bacterial species (33); however, its role in other bacteria remains undefined. The discovery of indoleacetic acidas a natural hormone in plants in the s was followed by the identification of several other natural hormones, gibberellins, cytokinins, abscisic acid, and ethylene in the s and of brassinosteroids and jasmonates in the s. Brassinosteroid (BR)-induced rice (Oriza sativa L.) lamina joint (RLJ) inclination and its relationship to indoleacetic acid (IAA) and ethylene were investigated using BR isolated from beeswax. The effect of BR on RLJ inclination was time- and concentration-dependent. Etiolated lamina were more sensitive to BR than green lamina. The BR-induced inclination was accompanied by increased lamina. christmas reflection paper
