Changes of the activity of IAA oxidase, tryptophan synthetase and cytokinin oxidase in sterile anther, leaf and ovule were similar to those of phytohormones.
棉花细胞质雄性不育花药、叶片和胚珠中，IA A氧化酶、色氨酸合成酶和细胞分裂素氧化酶活性的变化与内源激素含量的变化基本一致。
The activity of IAA oxidase and cytokinin oxidase was significantly higher in CMS anther, but the activity of tryptophan synthetase was lower than in fertile anther.
IAA氧化酶和细胞分裂素氧化酶活性表现为不育系高于其相应的可育系，色氨酸合成酶则是不育系低于其可育系。
These results suggest that MK-447 may selectively enhance the prostaglandin I2 (PGI2) level by acting as a tryptophan-like cofactor of PG endoperoxide synthetase.
研究结果提示，MK-447很可能是通过作为前列腺素酯氧酶色氨酸样协同因子，从而发挥选择性增加PGI_2生成的作用。
