Abstract
The DNA-binding with one finger (Dof) gene family is a class of plant-specific transcription factors involved in diverse biological processes, including response to biotic and abiotic stresses. Members of this family have been reported in the cultivated potato Solanum tuberosum, but clues to the roles of several Dof genes are still lacking. Potato wild relatives represent a genetic reservoir for breeding as they could provide useful alleles for adaptation to the environment and tolerance to biotic and abiotic stresses. We performed an in silico analysis to identify genes belonging to the Dof family in the wild potato S. commersonii, confirming that the identified Dof genes can be grouped in four classes (A, B, C, D), as reported for cultivated potato. A special focus was dedicated to Cycling Dof Factors (CDFs), which play a crucial role in plant responses to abiotic stresses. Analysis of available RNA-seq data confirmed CDF genes as regulated by stresses and often in a tissue specific manner. To ascertain their involvement in the stress response, S. tuberosum and S. commersonii plantlets growing in vitro were subjected to salt stress (80mM NaCl) for short (2 days) and prolonged (7 days) times. Analysis of phenotypic traits and qRT-PCR expression profiles of target CDF genes in aerial and root tissues showed differences between the two species. In addition, after saline treatment, changes in total phenols, proline, and malondialdehyde suggested a diverse perception of saline stress in S. commersonii vs. S. tuberosum. Overall, this study provided useful clues to the involvement of CDF genes in salt response and promoted the identification of potential candidate genes for further functional studies.

Assessment of the effect of ascorbic acid, sodium isoascorbate and calcium ascorbate treatments on the browning and wound healing process of fresh-cut potatoes. Food Chem 2024; 463:141454. [PMID: 39362097 DOI: 10.1016/j.foodchem.2024.141454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2024] [Revised: 09/14/2024] [Accepted: 09/26/2024] [Indexed: 10/05/2024]
Abstract
Browning significantly affects consumer perception, while texture hardening due to wound healing further reduces the commercial value of fresh-cut potatoes. This study evaluated the effects of 5 g L-1 ascorbic acid (AA), sodium isoascorbate (SI), and calcium ascorbate (CA) on browning and wound healing during ambient storage. The results indicated that AA and SI were more effective than CA and the control in delaying browning and wound healing. By day 3, browning levels in the AA and SI groups were reduced to 65 % and 62 % of the control, respectively, while lignin content decreased by 35 % and 40 %. Additionally, AA and SI treatments reduced reactive oxygen species (ROS) and improved antioxidant capacity, preserving appearance and texture. This study provides insights into the mechanisms of browning and wound healing, suggesting potential strategies for extending the shelf life and improving the quality of fresh-cut potatoes.

Abstract
Introduction Unintended wounding or bruising during harvest or postharvest handling leads to significant tuber loss and imposes economic burden to potato industry. Therefore, finding effective strategies to mitigate wound-related tuber losses is very important from industry perspectives. Formation of protective barrier through accumulation of suberin polyphenolics (SPP) is a natural and initial response of potato tuber tissues to wounding. Materials and methods In this study, efficacy of two natural elicitors, such as chitosan oligosaccharide (COS 0.125 g L-1) and cranberry pomace residue (Nutri-Cran 0.125 g L-1) was investigated using a mechanically wounded tuber tissue model and by histological determination of SPP formation in five agronomically relevant and red-skin potato cultivars (Chieftain, Dakota Rose, Dakota Ruby, Red LaSoda, Red Norland). Furthermore, the potential role of stress protective metabolic regulation involving phenolic metabolites, proline, and antioxidant enzymes in tuber WH processes were also investigated during 0-9 days after wounding. Results and discussion Exogenous treatments of both COS and Nutri-Cran resulted into enhanced SPP formation in wounded surface, but the impact was more rapid with Nutri-Cran treatment in select cultivars. Greater contents of total soluble phenolic, ferulic acid, chlorogenic acid, total antioxidant activity, and superoxide dismutase activity were also observed in elicitor treated tuber tissues at different time points after wounding. Nutri-Cran treatment also reduced the activity of succinate dehydrogenase in Red Norland and Dakota Ruby at 3 d, indicating a suppression in respiration rate. Collectively, these results suggest that Nutri-Cran can be potentially utilized as an effective WH treatment to potato tubers for minimizing wound-related losses.

Abstract
Postharvest physiological deterioration (PPD) reduces the availability and economic value of fresh produces, resulting in the waste of agricultural products and becoming a worldwide problem. Therefore, many studies have been carried out at the anatomical structural, physiological and biochemical levels and molecular levels of PPD of fresh produces to seek ways to manage the postharvest quality of fresh produce. The cell wall is the outermost structure of a plant cell and as such represents the first barrier to prevent external microorganisms and other injuries. Many studies on postharvest quality of crop storage organs relate to changes in plant cell wall-related components. Indeed, these studies evidence the non-negligible role of the plant cell wall in postharvest storage ability. However, the relationship between cell wall metabolism and postharvest deterioration of fresh produces has not been well summarized. In this review, we summarize the structural changes of cell walls in different types of PPD, metabolic changes, and the possible molecular mechanism regulating cell wall metabolism in PPD of fresh produce. This review provides a basis for further research on delaying the occurrence of PPD of fresh produce.

Abstract
Temperature is one of the important environmental factors affecting plant growth, yield and quality. Moreover, appropriately low temperature is also beneficial for tuber coloration. The red potato variety Jianchuanhong, whose tuber color is susceptible to temperature, and the purple potato variety Huaxinyangyu, whose tuber color is stable, were used as experimental materials and subjected to 20 °C (control check), 15 °C and 10 °C treatments during the whole growth period. The effects of temperature treatment on the phenotype, the expression levels of structural genes related to anthocyanins and the correlations of each indicator were analyzed. The results showed that treatment at 10 °C significantly inhibited the potato plant height, and the chlorophyll content and photosynthetic parameters in the leaves were reduced, and the enzyme activities of SOD and POD were significantly increased, all indicating that the leaves were damaged. Treatment at 10 °C also affected the tuberization of Huaxinyangyu and reduced the tuberization and coloring of Jianchuanhong, while treatment at 15 °C significantly increased the stem diameter, root-to-shoot ratio, yield and content of secondary metabolites, especially anthocyanins. Similarly, the expression of structural genes were enhanced in two pigmented potatoes under low-temperature treatment conditions. In short, proper low temperature can not only increase yield but also enhance secondary metabolites production. Previous studies have not focused on the effects of appropriate low-temperature treatment during the whole growth period of potato on the changes in metabolites during tuber growth and development, these results can provide a theoretical basis and technical guidance for the selection of pigmented potatoes with better nutritional quality planting environment and the formulation of cultivation measures.

Abstract
BACKGROUND Mechanical wounding (MW) is mainly caused due to high wind, sand, heavy rains and insect infestation, leading to damage to crop plants and an increase in the incidences of pathogen infection. Plants respond to MW by altering expression of genes, proteins, and metabolites that help them to cope up with the stress. METHODS AND RESULTS In order to characterize maize transcriptome in response to mechanical wounding, a microarray analysis was executed. The study revealed 407 differentially expressed genes (DEGs) (134 upregulated and 273 downregulated). The upregulated genes were engaged in protein synthesis, transcription regulation, phytohormone signaling-mediated by salicylic acid, auxin, jasmonates, biotic and abiotic stress including bacterial, insect, salt and endoplasmic reticulum stress, cellular transport, on the other hand downregulated genes were involved in primary metabolism, developmental processes, protein modification, catalytic activity, DNA repair pathways, and cell cycle. CONCLUSION The transcriptome data present here can be further utilized for understanding inducible transcriptional response during mechanical injury and their purpose in biotic and abiotic stress tolerance. Furthermore, future study concentrating on the functional characterization of the selected key genes (Bowman Bird trypsin inhibitor, NBS-LRR-like protein, Receptor-like protein kinase-like, probable LRR receptor-like ser/thr-protein kinase, Cytochrome P450 84A1, leucoanthocyanidin dioxygenase, jasmonate O-methyltransferase) and utilizing them for genetic engineering for crop improvement is strongly recommended.
