One type of these hormones was first discovered in a species of rice-plant pathogen named fujikuroi. Uniconazole (“uni-CON-uh-zole”) inhibits the production of this hormone through blockage of kaurene oxidase. The absence of these hormones can increase biomass growth in the roots and cause shortened internodes. The binding of these hormones causes the degradation of DELLA proteins like GAI. The (10[1])presence of water activates these hormones that stimulate (10[1])the production of (-5[1])hydrolytic enzymes in germinating seeds. (10[1])In elongating stems, these hormones’ concentration is regulated by (-5[1])auxins. (10[2])For 10 points, (10[1])name this (10[1])class of plant hormone that mediates developmental processes like stem elongation. ■END■ (10[2]0[2])
