The acid-insoluble nitrogen content, lipid content, and cytochrome oxidase activity in the mitochondrial fraction are found to increase during incubation of slices of sweet potato (Ipomoea batatas) root tissue. These increases appear to be related to an increase in the number of the mitochondrial particles. The increase in the mitochondrial fraction is not accompanied by an increase in cell number. The nitrogen content in the mitochondrial fraction increases prior to the changes in the activity of cytochrome oxidase and lipid content. The increase in the numbers of the mitochondrial particles lags behind the increase in the cytochrome oxidase activity. Such findings are also found in the tissue infected by Ceratocystis fimbriata.The respiratory increase in response to wounding and infection appears to be a result of an increase in mitochondrial particles.
在甘薯(Ipomoea batatas)根组织切片的孵育过程中,发现酸不溶性氮含量、脂质含量和线粒体部分的细胞色素氧化酶活性增加。这些增加似乎与线粒体颗粒数量的增加有关。线粒体部分的增加并不伴随着细胞数量的增加。线粒体部分的氮含量在细胞色素氧化酶活性和脂质含量的变化之前增加。线粒体颗粒数量的增加滞后于细胞色素氧化酶活性的增加。在被 Ceratocystis fimbriata 感染的组织中也发现了这种情况。对创伤和感染的呼吸增加似乎是线粒体颗粒增加的结果。
