“…n = 9 (3 replicates × 3 measurements for each application) for total phenolics. (Saniewski et al, 1987;Kondo et al, 2001;Rudell et al, 2005), ethylene and anthocyanin synthesis in Braeburn apples were clearly stimulated by MeJA treatments. It may be suggested that MeJA promoted anthocyanin production, and thus red skin development, by enhancing ethylene biosynthesis.…”

“…Involvement of ethylene alone promotes anthocyanin production in apples (Awad and Jager, 2002;Li et al, 2002). However, in some other studies on anthocyanin accumulation and peel color development in apple fruits, it was documented that ethylene alone had little effect on anthocyanin production (Kondo et al, 2001;Rudell and Mattheis, 2008). Similarly, Fan et al (1998) reported that MeJA promoted changes in L*, chroma, and hue angle, even in fruit without detectable ethylene production, indicating that some degree of MeJA response occurs independently of ethylene.…”

The present study was carried out to determine the effects of methyl jasmonate (MeJA) treatments on the fruit peel color parameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimental trees were treated with 1120, 2240, or 4480 mg L-1 MeJA at 1-and 2-week intervals between the 105th and 175th days of growth after full bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments did not cause significant changes in chroma, except for in the final harvest in 2010, it decreased chroma values significantly on all sampling dates of 2011. Anthocyanin content, internal ethylene concentration, phenolic content, and antioxidant capacity increased linearly with increasing MeJA concentrations, regardless of the application interval: MeJA treatments with 1-week intervals were found to be as effective as those with 2-week intervals. Although MeJA treatments increased ethylene biosynthesis, they did not cause any softening; on the other hand, fruit firmness increased linearly with increasing MeJA concentrations. Preharvest MeJA treatments can be a good management strategy for red peel color development and fruit firmness preservation in Braeburn apples. Although both application regimes of MeJA significantly increased red color development, the treatments with 1-week intervals were found to be more effective than 2-week intervals with regard to phenolic content and antioxidant capacity.

“…There has been extensive testing of growth conditions to improve anthocyanin synthesis in orchardgrown apples, including chemical sprays and plant hormones, the use of reflecting films on the canopy floor to alter light conditions and manipulation of the crop load, the canopy, and temperature conditions (Arakawa, 1988;Reay et al, 1998;Ju et al, 1999;Reay, 1999;Awad et al, 2001aAwad et al, , 2001bKondo et al, 2001;Reay and Lancaster, 2001;Iglesias et al, 2002;Layne et al, 2002;Embree and Nichols, 2005). The identification of an anthocyanin regulatory gene MdMYB1 provides a molecular tool to study the impact of these processes and conditions on anthocyanin synthesis and may provide a genetic solution to improving the consistency of color in apples.…”

Anthocyanins are secondary metabolites found in higher plants that contribute to the colors of flowers and fruits. In apples (Malus domestica Borkh.), several steps of the anthocyanin pathway are coordinately regulated, suggesting control by common transcription factors. A gene encoding an R2R3 MYB transcription factor was isolated from apple (cv Cripps' Pink) and designated MdMYB1. Analysis of the deduced amino acid sequence suggests that this gene encodes an ortholog of anthocyanin regulators in other plants. The expression of MdMYB1 in both Arabidopsis (Arabidopsis thaliana) plants and cultured grape cells induced the ectopic synthesis of anthocyanin. In the grape (Vitis vinifera) cells MdMYB1 stimulated transcription from the promoters of two apple genes encoding anthocyanin biosynthetic enzymes. In ripening apple fruit the transcription of MdMYB1 was correlated with anthocyanin synthesis in red skin sectors of fruit. When dark-grown fruit were exposed to sunlight, MdMYB1 transcript levels increased over several days, correlating with anthocyanin synthesis in the skin. MdMYB1 gene transcripts were more abundant in red skin apple cultivars compared to non-red skin cultivars. Several polymorphisms were identified in the promoter of MdMYB1. A derived cleaved amplified polymorphic sequence marker designed to one of these polymorphisms segregated with the inheritance of skin color in progeny from a cross of an unnamed red skin selection (a sibling of Cripps' Pink) and the non-red skin cultivar Golden Delicious. We conclude that MdMYB1 coordinately regulates genes in the anthocyanin pathway and the expression level of this regulator is the genetic basis for apple skin color.

Background: Plum fruits constitute a good source of natural antioxidant substances. Particularly, plums contain large amounts of phenolic compounds and flavonoids having natural antioxidant activity which is effective in human diet. The aim of this study was to evaluate the effects of pre-harvest MeJA treatment on the fruit quality and bioactive compounds of three different Japanese plums under storage conditions. Materials and Methods: The effects of pre-harvest methyl jasmonate treatment (MeJA) on weight loss, color characteristics (L*, C* and h°), firmness, soluble solids content (SSC), titratable acidity (TA), total phenolics (TP) and total antioxidant activity (TAA) of 'Black Beauty', 'Black Amber' and 'Fortune' plum fruits during the cold storage (at 0±0.5 C and 90±5% RH) were investigated in this study. Results: MeJA did not have significant effects on the weight loss (%) of 'Black Amber' and 'Fortune' fruits, whereas it was effective in delaying the weight loss of 'Black Beauty' at the end of storage. The color characteristics of all plum cultivars were not significantly affected by MeJA at the end of storage. In all plum cultivars, the SSC increased, while TA significantly (P<0.05) decreased during storage. TP and TAA of 'Black Amber' and 'Fortune' fruits significantly increased during the cold storage. MeJA treatments increased fruit firmness, TP and TAA (according to FRAP) of 'Fortune' plums at the end of storage. Conclusion:The scientific results about the effects of pre-harvest MeJA treatments on the cold storage of Japanese plums may contribute significant helps to improve plum storage durations and quality characteristics.
