摘要: The objective of the present work was to study biochemical alterations in lime plants infected by Candidatus Phytoplasma aurantifoliae. Changes antioxidant activities, content chlorophylls (Chl), carotenoids (Car), soluble proteins, sugars and auxin (IAA) plant were investigated. activities polyphenol oxidase (PPO), peroxidase (POX) superoxide dismutase (SOD) observed be greater leaves than healthy control. Also according non-denaturing PAGE, all antioxidative enzymes isoforms stronger that These results suggest can activated response infection phytoplasma. decrease total reducing point out changes host metabolism due phytoplasma infection. reduction shows interfere photosynthesis induces senescence leaf. In conclusion, this provides new insights into
