Integrative transcriptomics and metabolomics data exploring the effect of chitosan on postharvest grape resistance to Botrytis cinerea

Multifunctional Role of Chitosan Edible Coatings on Antioxidant Systems in Fruit Crops: A Review

“…CS-based coatings reduce ROS content in fruit cells during postharvest life. In fact, in CS/nano-silica treated loquat a reduction around ~35% and ~69% in the O 2 •− and H 2 O 2 content has been observed [ 37 ], while in mango and nectarine coated with high MW CS a significant reduction ( p ≤ 0.05) in H 2 O 2 content has been registered [ 8 , 38 ]. Similarly, H 2 O 2 , O 2 − and OH content, in apple slices treated with S-nitrosoglutathione-CS nanoparticles (GSNO-CS NPs) represented 50.20%, 48.67%, and 27.63% of that in the control after 4 days of cold storage, respectively [ 32 , 39 ] showed that GSNO-CS NPs coated sweet cherry contained a significantly lower level of ROS content at the end of storage.…”

“…Several studies demonstrated that CS-based coating reduced the MDA increase in strawberry [ 45 , 46 , 47 , 48 , 49 ], mango [ 50 , 51 ], loquat [ 37 , 52 ], grape [ 38 , 53 ], lemon [ 54 ], nectarine [ 55 ], pomegranate [ 42 ], plum [ 56 ], majiayou pummelo [ 40 ], cherimoya [ 41 ], sweet cherry [ 57 ], and apple [ 46 ] during storage. These findings suggest a low degree of lipid peroxidation in CS coated fruits.…”

“…AA levels change throughout fruit ripening and storage in fruit crops-dependent manner due to different regulation of its metabolism [ 45 , 65 ]. CS-based coatings regulate the passage of oxygen from the external environment into the fruit, inhibiting the activity of ascorbate oxidase, responsible to the AA oxidation [ 38 ]. CS was found to be effective in restricting the losses of AA when applied as a coating on fruits such as plum [ 56 ], litchi [ 66 ], sweet cherry [ 11 ], longan [ 67 ], mandarin [ 68 ], majiayou pummelo [ 40 ], red kiwifruit [ 69 ], and pomegranate [ 64 , 70 ].…”

“…Similarly, in CS/nano-silica coated loquat, SOD activity increased and remained higher than that in uncoated fruit, especially from 20 days to 40 days of storage [ 37 ]. An increase in SOD activity were displayed in grape treated with CS coating after 12 days of inoculation with Botritis cinerea with higher value in “Shine Muscat” compared to “Kyoho” grape [ 38 ]. Likewise, in CS coated avocado was registered a high SOD activity in artificially or naturally inoculated fruit with either C. gloeosporioides or Lasiodiplodia theobromae after 5 days of shelf life [ 59 ].…”

“…CAT, APX, and GPX activities increased after 12 days of inoculation with B. cinerea in “Shine Muscat” and “Kyoho” grape treated with CS coating, with higher values in “Shine Muscat” [ 38 ]. Likewise, a high CAT activity was registered in CS coated avocado fruit artificially or naturally inoculated with either C. gloeosporioides or L. theobromae after 5 days at 18 °C [ 59 ].…”
