“…L‐Phenylalanine was catalyzed to trans‐cinnamic acid by PAL and then to hydroxycinnamic acid by C4H to synthesize precursors for lignin biosynthesis, such as coumaric acid, ferulic acid, and caffeic acid (Ferrer et al, ). Hydroxycinnamic acid and trans‐cinnamic acid could also be converted to coumaric acid‐CoA in the presence of 4CL (Liu et al, ). Activities of PAL, C4H and 4CL had been reported to have similar variation tendency in muskmelon (Wang et al, ), loquat (Jin, Duan, Wang, & Zheng, ; Liu et al, ) and bayberry (Wang, Cao, Jin, Rui, & Zheng, ).…”

“…A significant positive correlation ( p < .05) was observed between POD activity and the lignin content (Table ). The up‐regulation of POD was widely accepted to result in increased lignin (Liu et al, ; Yuan et al, ). Overall, POD was the only enzyme that had a direct impact on lignin accumulation by postharvest fresh waxy corn in this study.…”

“…The phenylpropanoid pathway plays an important role in plant disease resistance (Liu et al, ; Peña‐Neira, Cácere, & Pastenes, ). Harvest, storage and microorganism infection can all induce changes in this pathway, thus influencing downstream pathways and metabolites and resulting in changes in tenderness.…”

“…Postharvest effects on lignification have been described for bamboo shoots (Luo, Xu, & Yan, ), strawberry (Xu et al, ), muskmelon (Liu et al, ; Wang et al, ; Yuan et al, ), red raspberry (Flores & Castillo, ), walnut (Araji et al, ), asparagus (An, Zhang, & Lu, ), and zucchini fruit (Carvajal, Palma, Jamilena, & Garrido, ). The treatments used to influence lignification included the following: packaging in a modified atmosphere (Shen, Kong, & Wang, ), harpin (Tang et al, ; Wang et al, ), methyl jasmonate treatment (Flores & Castillo, ), blue‐light irradiation (Xu et al, ), acibenzolar‐S‐methyl treatment (Liu et al, ), chlorine dioxide treatment (Yang et al, ), and a hot water dip (Luo et al, ; Yuan et al, ). Most of the studies focusing on lignification or related enzyme activity have proved some effect on preservation during storage.…”

Lignification and changes in the enzymes involved in lignin biosynthesis were investigated in relation to the reduced tenderness occurring during the postharvest storage of fresh waxy corn at 20 °C. The firmness of the corn and its lignin and polyphenol contents increased as storage time increased. The lignin content was significantly correlated (p < .05) with the polyphenol content and firmness. Phenylalanine ammonia‐lyase was not the rate‐limiting enzyme in polyphenol biosynthesis, whereas the cinnamate 4‐hydroxylase activity was significantly correlated (p < .05) with the polyphenol content. The activity of coenzyme A ligase (4CL) had a limited effect on the polyphenol content. Peroxidase was significantly correlated (p < .05) with the lignin content, while no significant (p > .05) effect of polyphenol oxidase or cinnamyl alcohol dehydrogenase (CAD) on the lignin content was observed. Practical applications Tenderness is a main factor in sensory quality of fresh waxy corn. Secondary cell wall lignifications induced by phenylpropanoid pathway is the main reason of tenderness decline for postharvest fresh waxy corn. But little information of lignin accumulation of fresh waxy corn is obtained from the present studies. Analyzing the changes of lignin and related precursor materials, enzyme activities will help to comprehensively understand the regulatory mechanism of postharvest lignification of fresh waxy corn, which can provide suitable methods to delay postharvest lignin accumulation, and maintain the eating quality of fresh waxy corn.

Cold Storage and Biocontrol Agents to Extend the Storage Period of ‘BRS Isis’ Seedless Table Grapes

et al. 2018

'BRS Isis' is a novel hybrid seedless table grape with large reddish bunches. This cultivar is cultivated in tropical and subtropical areas and has potential to be exported overseas; however, under these growth conditions, grapes can be severely damaged by gray mold (Botrytis cinerea), the main postharvest disease of table grapes. Thus, this study aimed to evaluate different pre-and postharvest strategies to extend the storage period of 'BRS Isis' seedless table grapes. The treatments consisted of grapes packed into carton boxes under cold storage (1 • C and high relative humidity), pre-and/or postharvest treatment with potassium bicarbonate or a biological control agent (Bacillus subtilis), all with Botrytis inoculation. Additionally, two controls, with and without Botrytis inoculation, were also evaluated. The experimental design was completely randomized with eight treatments and three replications, and each plot consisted of four bunches. After a 50-day cold storage period, the carton boxes were kept for five days at room temperature (22 • C). Gray mold incidence and water loss, as well as soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, and color attributes were evaluated during both periods. Cold storage effectively reduced gray mold in 'BRS Isis' seedless grape for a period of 50 days, even when grapes were inoculated; however, no difference among treatments was observed. Higher water loss was observed in both non-treated control treatments.

Fresh‐cut lettuce has a short shelf‐life due to enzymatic browning and oxidative senescence. The present study investigated effects of polysaccharide‐based edible coatings (alginate, chitosan, and carrageenan) on enzymatic browning and antioxidant defense system of fresh‐cut lettuces during cold storage (4°C) for 15 days. The results showed that three coatings could inhibit enzymatic browning through maintaining total phenolics (TP) content and decreasing polyphenol oxidase (PPO) and phenylalanine ammonialyase (PAL) activities. These coatings also reduced phospholipase D (PLD) and lipoxygenase (LOX) activities, lowered malondialdehyde (MDA) content, and enhanced antioxidant enzymes (superoxide dismutase, SOD; peroxidase, POD; catalase, CAT; ascorbate peroxidase, APX) activities. Besides, all coatings positively affected sensory properties of fresh‐cut lettuces after 3 days storage. Additionally, among three coating treatments, chitosan coating had the most positive effects on quality of fresh‐cut lettuce and was the most suitable coating for retarding enzymatic browning and alleviating membrane oxidative damage. These results indicated that polysaccharide‐based edible coatings were helpful to maintain quality, inhibit enzymatic browning, and postpone senescence of fresh‐cut lettuce.
