“…The weight loss (%) in potato during the postharvest storage is associated with moisture loss due to evapotranspiration and dry matter loss due to respiration and sprouting (Tester et al 2005). Decreasing sprouted and decayed percent by using sprout-preventing chemicals was also reported by Lulai et al (1995) and Platonova et al (2010) as a result of using jasmonate for inhabiting sprouting of tubers and maintaining their processing quality. The beneficial effects of using CIPC to control tuber dormancy and prevent sprouting was earlier reported by many researchers (Corsini et al 1979;Mondy, 1993;Baloch, 1999;Pringle et al 2009 andBarbara et al 2011).…”

The present investigation was carried out on Diamant potato tubers (Solanum tuberosum L.), harvested at their commercial maturity stage (May, 2017) in a private farm at Kom Hamada Behira Governorate, Egypt. The selection of tubers was based on size, absence of physical injuries, mechanical damage and disease infection. Tubers were packed in net plastic boxes (15 kg/ box), and were surface-disinfected by dipping in 2% sodium hypochlorite for 2-4 mins, then rinsed with tap water and air-dried. Potato tubers were immersed in solutions containing chlorpropham (CIPC) at 0, 50, 75 and 100 ppm and jasmonic acid (JA) at 0, 0.001, 0.01 and 0.1 mM/L, either alone or in combinations for 20 minutes and then were cured in the dark for one week at 20°C and 75% RH. After curing, the tubers were placed in the dark cold storage room for long-term storage (140 days) at 10±1°C and 85±5% relative humidity (RH). Treatments were distributed in design with three replicates for each treatment (one replicate = one box of 15 kg tubers).Tuber's firmness, dry matter, starch, acidity and ascorbic acid increased, while SSC and total sugars decreased with increasing concentration of CIPC. Chlorpropham at the concentration of 75 ppm of decreased the weight loss, decay and sprouting percent during cold storage or after removal from cold storage and kept at ambient temperature as compared with 50 or 100 ppm and control. Furthermore, the storability and shelf life of potato tubers have been extended significantly with 75 ppm in both the storage temperature conditions. Likewise, applied of jasmonic acid at rate of 0.01 mM JA/L caused noticeable increase in tubers firmness, dry matter, starch, acidity and ascorbic acid contents. Meanwhile, soluble solids content, total sugars, weight loss, decay and sprouting percent decreased during storage as compared with the other concentrations of jasmonic acid (0.001 or 0.1 mM JA/L) and the untreated tubers. Additionally, the storage and shelf life of tubers have been extended significantly with 0.01 mM JA/L dips during cold storage or ambient temperature at 25±2°C and 75-80 % RH.

“…Wang (1998) highlighted that the application of MeJa inhibits sprouting in vegetables that are stored at room temperatures, especially on the commercialization stage. Moreover, other studies have reported that MeJa acts suppressing sprouting, particularly in potatoes (Platonova and Korableva 1992;Platonova et al 2010). In the present study, likewise, the application of MeJa reduced sprouting incidence rate and prolonged root shelf life, increasing, therefore, its potential of commercialization.…”

High incidence of sprouts and loss of quality of sweet potato is one of the negative aspects that compromises the commercialization most, and the methods of sprout control are still very limited. The appearance of sprouts promotes the wilting of sweet potato roots, reducing their commercialization period. The main objectives of this study were to evaluate sprout control and physiological and biochemical changes, in addition to the impact on the quality of postharvest chips in sweet potato roots cultivar BRS Cuia treated with methyl jasmonate (MeJa) and nonanoic acid (NA). Roots were fogged with 10 μmol•L -1 MeJa or 5 μmol•L -1 NA applied at first sprout initiation and control. Physiological and biochemical alterations such as fresh weight loss assessment, sprouting incidence and sprout length, total soluble sugars, reducing sugars, nonreducing sugars, enzymatic peroxidase and polyphenol oxidase, chips quality after frying were then assessed. Besides that, to determine the influence of treatments and storage periods, multivariate analysis was also performed using the main components. The MeJa reduced the incidence of sprouting and maintained the root quality during storage at room temperature.Notably, such events led to an increased both shelf life and potential of commercialization. Moreover, MeJa-treated chips displayed lighter color appearance after frying than control and NA-treated roots. Roots fogged with NA did not suppress the growth of sprouts, which consequently triggered a higher browning intensity in fried sweet potato chips.

“…JAs are mainly involved in pathogen defense in many higher plants, whereas JAs has a specific role of tuber-inducing activities in potato [ 11 , 14 ]. Numerous studies have focused on the favorable effects of JAs on tuber development [ 14 , 17 , 18 ]. However, the underlying molecular mechanism of tuber development regulated by JAs is still largely unknown.…”

“…The roles of JA in tuber formation mainly contribute to promoting radial cell expansion, meristem enlargement and early vascular tissue differentiation, thus facilitating the movement of substances to stolon tips [ 16 , 17 ]. JA also stimulates the biosynthetic activity of plastid apparatus in the apical meristem cells of tubers for starch accumulation [ 18 ]. Further evidences for the involvement of JAs in potato tuberization have derived from affecting the expression of enzymes or proteins involved in JAs biosynthesis or signaling pathway.…”

Background Jasmonates (JAs) are one of important phytohormones regulating potato tuber development. It is a complex process and the underlying molecular mechanism regulating tuber development by JAs is still limited. This study attempted to illuminate it through the potential proteomic dynamics information about tuber development in vitro regulated by exogenous JA. Results A combined analysis of physiological and iTRAQ (isobaric tags for relative and absolute quantification)-based proteomic approach was performed in tuber development in vitro under exogenous JA treatments (0, 0.5, 5 and 50 μΜ). Physiological results indicated that low JA concentration (especially 5 μM) promoted tuber development, whereas higher JA concentration (50 μM) showed inhibition effect. A total of 257 differentially expressed proteins (DEPs) were identified by iTRAQ, which provided a comprehensive overview on the functional protein profile changes of tuber development regulated by JA. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis indicated that low JA concentration (especially 5 μM) exhibited the promotion effects on tuber development in various cellular processes. Some cell wall polysaccharide synthesis and cytoskeleton formation-related proteins were up-regulated by JA to promote tuber cell expansion. Some primary carbon metabolism-related enzymes were up-regulated by JA to provide sufficient metabolism intermediates and energy for tuber development. And, a large number of protein biosynthesis, degradation and assembly-related were up-regulated by JA to promote tuber protein biosynthesis and maintain strict protein quality control during tuber development. Conclusions This study is the first to integrate physiological and proteomic data to provide useful information about the JA-signaling response mechanism of potato tuber development in vitro. The results revealed that the levels of a number of proteins involved in various cellular processes were regulated by JA during tuber development. The proposed hypothetical model would explain the interaction of these DEPs that associated with tuber development in vitro regulated by JA.
