摘要: An antibody raised against apple polyphenol oxidase (PPO) cross-reacted with PPOs from Japanese pear (Pyrus pyrifolia), communis), peach (Prunus persica), Chinese quince (Pseudocydonia sinensis) and loquat (Eriobotrya japonica). Core fragments (681 bp) of the corresponding PPO genes were amplified characterized. The deduced protein sequences showed identities 85.3 to 97.5%. Chlorogenic acid activity these higher activities when assayed at pH 4 than 6. These results indicate that in Rosaceae plants are structurally enzymatically similar.
