摘要：

Protein synthesis in mitochondrial and supernatant fractions of sweet potato root tissue was found to be activated up to about 3 and 1.5 times in response to wounding, respectively. The activation seemed to take place within 8 hr after slicing. Sucrose density gradient centrifugation of mitochondrial fraction prepared from the aged sliced tissue showed the presence of new fraction of mitochondrial particles which were not seen in the case of fresh tissue. The particles in the fraction were labeled by radioactive leucine in vivo more rapidly than the other particles. Chloramphenicol treatment of tissue before aging blocked the development of these particles. These results suggest that the particles were newly formed during aging. © 1969 Taylor and Francis Group LLC.
