Summary: This study compared the changes in metabolite abundance in two nectarine varieties (Andes Nec-2 and Andes Nec-3) with different susceptibility to mealiness during cold storage using GC-MS analysis. The results showed that in unripe nectarines, cold storage led to an increase in the accumulation of amino acids, whereas in ripe nectarines, it resulted in a decrease in amino acid accumulation and an increase in the abundance of sugars and organic acids. Pathway reconstruction revealed that cold storage disrupted metabolite abundance in sugar metabolism and the TCA cycle in ripe nectarines, leading to differential accumulation of amino acids, organic acids, and sugars in mealy and juicy nectarines.

Summary: Cold storage is used to extend the marketability of peaches, but it can cause chilling injury. This research aimed to determine the incidence of chilling injury in peaches stored at different temperatures, and to identify key aroma volatile compounds that could predict early stage CI development. The study found that fruit stored at 5 degrees C were sensitive to chilling injury, displaying impaired ethylene production and alterations in fruit texture and aroma profiles.

Summary: In this study, we found that the ethylene-responsive transcription factor PpRAP2.12 directly binds to the PpVIN2 promoter and enhances its activity, leading to increased invertase activity and decreased sucrose levels in peach fruit. Overexpression of PpRAP2.12 in tobacco reduces cold tolerance and increases VIN expression and activity, as well as reactive oxygen species production. Therefore, PpRAP2.12 acts as a negative regulator of cold resistance in plants and could be a potential target for mitigating chilling injury in peach fruit.

Summary: The study aims to understand how peach and nectarine tree varieties respond to winter and spring temperatures and evaluate the effectiveness of different chill and heat accumulation models in predicting bloom dates under various climatic conditions. The researchers analyzed data from 14 cultivars grown in 11 European locations and found significant variations in chill accumulation and rest completion among sites. They also observed that bloom timing is strongly influenced by delayed rest completion and heat accumulation. The Dynamic Model showed better predictions of bloom dates compared to other models. However, further research is needed to improve the reliability of climatic requirements for peach cultivars and provide guidance for adapting peach production to changing climate conditions.

Summary: Peaches and nectarines are widely exported from Chile to the Northern Hemisphere, with fruit quality being determined by factors such as size, taste, and aroma. Thinning practices can impact fruit metabolic composition at early stages of development, with soluble sugars, organic acids, and phenylpropanoid pathway intermediates serving as potential indicators of fruit quality.

Summary: UV-B radiation can modulate the secondary metabolism in peach fruit by enhancing the biosynthesis of specific phenolic subclasses, leading to metabolic changes within the flesh. The impact of UV-B on peach flesh metabolome is significant, especially in the increase of terpenoids, phenylpropanoids, phytoalexins, and fatty acids.UV-B radiation does not penetrate below the skin, indicating a possible signaling pathway between tissues.

Summary: This study investigated the qualitative traits and chemical properties of various peach and nectarine cultivars with different flesh colors and pomological characteristics. It was found that yellow nectarines exhibited higher variability in soluble solids concentration and titratable acidity values. The analysis of color parameters revealed a significant interaction between pulp color and fruit types. Sucrose was identified as the main sugar in both peach and nectarine fruits, with higher percentages in yellow flesh. Variability among cultivars was observed for the analyzed chemical compounds.

Summary: This study aimed to investigate the storability potential of Orange Red and Orange Rubis apricots during cold storage at either 1℃ or 5℃, followed by shelf life at 20℃. Variables evaluated included various quality parameters and antioxidant concentrations. The main results showed that storage at 5℃ led to higher weight loss and chilling injury symptoms, increased ethylene production, while storage temperature had limited effect on firmness, color, and antioxidants. Orange Red exhibited higher ethylene production rates and antioxidant concentrations. In conclusion, storage at 1℃ retained quality and both cultivars were marketable up to 21 days without shelf life, or up to 14 days with shelf life. However, Orange Rubis showed chilling injury symptoms after 14 days, while Orange Red showed symptoms after 21 days of storage.

Summary: The biggest threat to profitable peach production is cold damage to reproductive tissues. Accurate and efficient assessment of floral bud cold hardiness (Hc) is crucial in order to better understand and mitigate cold damage in peach. The use of differential thermal analysis (DTA) was optimized to determine Hc weekly during the dormant season by detecting low-temperature exotherms (LTE) created by the freezing of supercooled intracellular water in peach floral primordia. The results confirm that DTA is an efficient and accurate method to determine Hc in peach floral buds.

Summary: Grafting, an ancient plant propagation technique widely used in horticultural crops like fruit trees, may lead to graft-incompatibility when involving different species. This incompatibility can be classified into localized and translocated categories, with more emphasis on understanding the mechanisms of the latter type in peach/plum graft-combinations. The study highlighted biochemical and molecular factors involved in translocated graft-incompatibility.

Summary: Dormancy is an adaptive strategy in plants to survive under unfavorable climatic conditions. The lack of direct markers for dormancy and forcing periods makes it difficult to determine the end of dormancy.

Summary: This study evaluated 155 apple samples over a five-year period, analyzing four individual sugars and seven organic acids and studying the influence of genetics and climate on apple characteristics. The results showed that genetics had the strongest effect, with clear differences between different genetic groups, while climate had a more equal effect on different genetic groups for certain compounds. Precipitation, temperature range, and solar radiation were found to be negatively and positively correlated with the concentrations of sugars and acids. The study also highlighted the importance of the geographic region where the orchard is located.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.
