“…A decline in abundance of CAT under the present study may suggest a reduced capacity in removal of H 2 O 2 and toxic peroxides which may resulted in an increase in the free radical initiation of lipid peroxidation with fruit ripening. In the CAT deficient lines of Arabidopsis plants, GSTs were induced (Lv et al, 2020). This relationship between CAT and GSTs is confirmed in this study and may reflect a simple association with the loss of chloroplast function as the fruit ripen from white to red.…”

“…SOD has been reported to increase in apple fruit during ripening (Zheng et al, 2007). While in another study on apples, SOD activity in both pulp and peel increased and later decreased, which coincided with the change of respiration rate and H 2 O 2 content (Lv et al, 2020), indicating that ethylene may play a role in the regulation of gene expression of SOD in apples.…”

“…Decrease of CAT2 gene expression in Arabidopsis plants after flowering was shown, suggesting an integral part in H 2 O 2 triggered leaf senescence (Zimmermann et al, 2006). Reduction in CAT activity under stress conditions has been attributed to the inactivation of enzymes due to ROS (Lv et al, 2020). Measuring the activities of CAT, SOD and peroxidase in "Chandler" strawberry fruit during development and fruit ripening reported that activity of CAT increased, while SOD and peroxidase decreased from white to red ripe fruit (López et al, 2010).…”

Proteomic Changes in Antioxidant System in Strawberry During Ripening

To investigate the strawberry antioxidant defense system during fruit ripening, a targeted quantitative proteomic approach using multiple reaction monitoring (MRM) was developed to investigate targeted proteins in the antioxidant enzyme system in strawberry fruit. We investigated 46 proteins and isoforms with 73 identified peptides which may be involved in this antioxidant enzyme system. Among the proteins that changed during ripening, aldo/keto reductase (AKR), superoxide dismutase (SOD) and glutathione transferase (GT) increased significantly, while dehydroascorbate reductase, 2-Cys peroxiredoxin, catalase (CAT), 1-Cys peroxiredoxin and L-ascorbate peroxidase (APX) decreased significantly. These results suggest that fruit ripening of strawberry activates the enzymes of an SOD/glutathione metabolism system. The methodologies used in this study will be useful for systematically characterizing the role of antioxidant enzymes in fruit ripening of other plants.

“…Likewise, under 1-methylcyclopropene (1-MCP) supplementation, apple ( Malus×domestica Borkh.) fruits showed a higher expression of Cu/ZnSODs, MnSODs, and FeSODs [ 20 ]. In short, these findings showed that improved SOD activity and higher expression of SOD-encoding genes can contribute to plant tolerance to multiple stresses.…”

Superoxide dismutase (SOD) is an important enzyme that acts as the first line of protection in the plant antioxidant defense system, involved in eliminating reactive oxygen species (ROS) under harsh environmental conditions. Nevertheless, the SOD gene family was yet to be reported in rapeseed (Brassica napus L.). Thus, a genome-wide investigation was carried out to identify the rapeseed SOD genes. The present study recognized 31 BnSOD genes in the rapeseed genome, including 14 BnCSDs, 11 BnFSDs, and six BnMSDs. Phylogenetic analysis revealed that SOD genes from rapeseed and other closely related plant species were clustered into three groups based on the binding domain with high bootstrap values. The systemic analysis exposed that BnSODs experienced segmental duplications. Gene structure and motif analysis specified that most of the BnSOD genes displayed a relatively well-maintained exon–intron and motif configuration within the same group. Moreover, we identified five hormones and four stress- and several light-responsive cis-elements in the promoters of BnSODs. Thirty putative bna-miRNAs from seven families were also predicted, targeting 13 BnSODs. Gene ontology annotation outcomes confirm the BnSODs role under different stress stimuli, cellular oxidant detoxification processes, metal ion binding activities, SOD activity, and different cellular components. Twelve BnSOD genes exhibited higher expression profiles in numerous developmental tissues, i.e., root, leaf, stem, and silique. The qRT-PCR based expression profiling showed that eight genes (BnCSD1, BnCSD3, BnCSD14, BnFSD4, BnFSD5, BnFSD6, BnMSD2, and BnMSD10) were significantly up-regulated under different hormones (ABA, GA, IAA, and KT) and abiotic stress (salinity, cold, waterlogging, and drought) treatments. The predicted 3D structures discovered comparable conserved BnSOD protein structures. In short, our findings deliver a foundation for additional functional investigations on the BnSOD genes in rapeseed breeding programs.

“…Non-coding RNA is especially primary within the increased shelf life of vegetables and fruits. Tobacco (Moreno et al, 2020), and tomatoes (Arefin et al, 2020), superoxide dismutase (SOD) genes expressed at some stage in the ripening of apple fruit (Lv et al, 2020), cold storage responses genes in the peach (Antonella et al, 2020), blueberry cultivars with higher fruit firmness and longer shelf lifestyles (Liu et al, 2021), preserved postharvest shelf life and quality of banana fruit (Yumbya et al, 2021) have been developed using RNAi. RNAi method concentrated on suppression of more than one homolog would be much effective than the knockdown of a single homolog (Gupta et al, 2013).…”

Thanks to committed plant breeding researchers over the few decades, many problems associated with food supply and qualities have been improved. Food security is an exceptionally serious worldwide issue via world climate change, the increase in human population, and the use of plants for bioethanol production in current years. Improved tolerance to abiotic and biotic stress, resistance to herbicides, improved yield, and plants with wonderful nutritional value are essential goals of crop improvement. RNAi applications are the modern innovation that can assist in the solution for these issues. A natural protection mechanism against invading viruses, nucleic acids, and transposons non-coding RNAs (ncRNAs), are identified as effector molecules in RNA-mediated gene silencing and used in the genetic modification of crops. These ncRNAs are concerned with the regulation of growth, development, and response to stress at the transcriptional and translational levels. Improving crop yields is the final purpose of molecular plant breeding. ncRNAs, along with transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), as well as small non-coding RNAs (sncRNAs) and the long non-coding RNAs (lncRNAs), have been recognized as essential regulators of gene expression in plants in plant immunity and adaptation to abiotic and abiotic stages biotic stress.
