07/15/2014 - "In vivo study of spoilage bacteria on polyphenoloxidase activity and melanosis of modified atmosphere packaged Pacific white shrimp."
01/01/2015 - "Polyphenoloxidase (PPO), the copper-containing metalloprotein involved in oxidation of phenol to quinone is the major biochemical reaction of melanosis formation. "
|2.||Weight Loss (Weight Reduction)
06/01/2015 - "The quality characteristics (that is, color, weight loss, texture, pH, polyphenoloxidase activity, and total phenolic content) of the AA + CM-dipped sample in 100% CO2 packaging were maintained significantly better than those of the other samples (P < 0.05). "
05/12/2010 - "The results showed that after 18 days of storage, the weight loss, respiratory intensity, and polyphenol oxidase (PPO) activity of fruits treated with the complex were 11.72, 31.51, and 7.07% lower than the control. "
09/01/2014 - "All treatments prevented product weight loss and decrease in polyphenoloxidase and peroxidase activities during storage. "
03/14/2012 - "Mushroom respiration rate, weight loss, firmness, color, percent open caps, total soluble solids, microbial and activities of polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL), and peroxidase (POD) were measured. "
04/15/2014 - "Changes in the browning index (BI), weight loss, firmness, percentage of open caps, total phenolics, ascorbic acid, microbial activity and activities of polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL), and peroxidase (POD) were measured. "
|3.||Wounds and Injuries (Trauma)
07/01/2004 - "Polyphenol oxidase (PPO; EC 126.96.36.199 or EC 188.8.131.52) takes part in the response of tomato plants (Lycopersicon esculentum Mill.) to wounding and herbivore attack, mediated by the octadecanoid wound-signaling pathway. "
01/17/1995 - "Systemin activates synthesis of wound-inducible tomato leaf polyphenol oxidase via the octadecanoid defense signaling pathway."
06/01/1991 - "A correlation between peroxidase activity and wound-induced browning was observed, whereas no relationship between polyphenol oxidase activity and browning was found. "
01/01/2008 - "Expression analyses for 29 genes showed that expression of wound-inducible genes such as those coding for PROTEINASE INHIBITOR2, POLYPHENOL OXIDASE, THREONINE DEAMINASE or ARGINASE was induced by JAME and less induced or even down-regulated by 12-OH-JA and 12-HSO(4)-JA. "
02/01/2004 - "Application of regurgitant from Leptinotarsa decemlineata Say on wound surfaces of one wounded leaf of intact bean (Phaseolus vulgaris L.) plants resulted in activation of ethylene biosynthesis followed by an increase of both peroxidase and polyphenol oxidase activity. "
|4.||Dehydration (Water Stress)
02/01/2001 - "Polyphenol oxidase activity, color changes, and dehydration in table grape rachis during development and storage as affected by n-(2-chloro-4-pyridyl)-n-phenylurea."
07/01/1975 - "However, catechol oxidase activity rises sharply during the later stages of development, shows a further abrupt rise during dehydration of the seed coat, and then decreases. "
04/01/2013 - "The dynamic balance between the antioxidant pattern and polyphenol oxidase activity under water stress conditions resulted in fruits with increased antioxidant activity (+12%), due to a decline in enzyme activity (-48%) and a rise in vitamin C (+20%) and total phenolic (+13%) contents. "
12/01/2011 - "It was recently reported that during osmotic dehydration of ascorbic acid (AA)-treated apple cubes, losses in AA and phenolics could partly arise from enzymatic oxidation, provided polyphenoloxidase (PPO) was still active under the processing conditions. "
05/01/2007 - "In agreement with these findings, glutathione content and polyphenol oxidase activity were found to increase upon dehydration and rapid recovery of photosynthesis was observed."
12/01/2001 - "Changes of apple phenolics and polyphenol oxidase activity during cold storage and the biological activity of these phenolics have also been analyzed with reference to the development of quiescent infections during cold storage plus shelf life at room temperature. "
06/01/2015 - "Regarding defense-associated enzyme levels, only following infection did grass grown in Si-amended soil exhibit greater activities of peroxidase and polyphenol oxidase than equivalent inoculated control plants. "
02/01/2006 - "However, gentisic-acid treatments strongly induced polyphenol oxidase activity in cucumber, whereas pathogen infection or SA treatment resulted in a lower induction of this enzyme. "
02/01/2015 - "Additionally, a significantly enhanced accumulation of antioxidant peroxidase (POX) and polyphenol oxidase (PPO) enzymes was observed in the PGPR-pretreated plants with or without pathogen infection in comparison with water or pathogen control. "
07/15/2013 - "Consistent with the observation that the SAR provided the highest level of protection when the time interval between primary infection and challenge inoculation was 10d, the activities of defense-related enzymes such as phenylalanine ammonia lyase (PAL, EC 184.108.40.206), peroxidase (POD, EC 220.127.116.11), polyphenol oxidase (PPO, EC 18.104.22.168), and superoxide dismutase (SOD, EC 22.214.171.124) in systemic tissues also reached the maximum level and were 2.00-2.43 times higher than that of the corresponding controls on the tenth day.
