Abstract
In order to explore the molecular mechanism of fresh-cut operation accelerating senescence and quality deterioration of Z. latifolia, the response of dynamic proteome change in Z. latifolia to fresh-cut operation during room temperature (25 °C) storage was studied. 35 protein spots were identified to change significantly (p<0.05) from the total 660 protein spots on the gels by MALDI-TOF/TOF. Compared with the control, 29 proteins showed similar expression pattern after fresh-cut operations in spite of the difference in abundance between two treatments. Meanwhile, six spots (plant basic secretory protein, adenosine kinase, C2 domain, class III peroxidases, LbH_gamma_CA_like, small Ras-related GTP-binding protein), which were down-regulated in whole Z. latifolia, increased after fresh-cut operation during storage. Fresh-cut operations that accelerate senescence and quality deterioration of Z. latifolia might be due to the production and transduction of wounding signals, acceleration of carbohydrate and nucleotide catabolism, disorder of energy homeostasis, enhancement of free radical damage, as well as degradation of cell structure.
