Summary: In this study, MdPAT16 was identified as a key player in mediating salt stress response in apple plants through palmitoylation of target proteins. Overexpression of MdPAT16 improved plant salt stress resistance and promoted the accumulation of soluble sugars. Furthermore, MdPAT16 was shown to interact with MdCBL1 and stabilize its protein levels through palmitoylation, suggesting a potential missing link in the plant salt stress response pathway.

Summary: The impact of apple cultivars and processing methods on the texture of purees was investigated in this study. Viscosity of purees varied significantly between different cultivars, with Granny Smith cultivar showing the highest viscosity due to its firm fruits and large particles. Mealy Braeburn apples had lower viscosity purees compared to non-mealy ones, attributed to reduced cell adhesion. Processing method also affected the viscosity of purees, with high temperature-low shear process resulting in more viscous purees.

Summary: Propagation through stem cuttings is a popular method for clonal propagation of certain tree species. This study investigates the regulatory mechanisms of adventitious root formation in apple trees. The research identifies the gene MdBRC1 as a key player in inhibiting adventitious root formation. The study also proposes potential target genes and the use of CRISPR technology to enhance adventitious root formation in woody plants.

Summary: A high-performance nitrogen-doped chitosan-TiO2 nanocomposite was successfully prepared by a simple precipitation method and showed significant photocatalytic activities for the degradation of patulin in apple juice. The nanocomposite effectively degraded patulin within 35 minutes under ultraviolet irradiation, with little impact on the quality of apple juice.

Summary: Bagging is an important technique for producing high-quality fruits, but it can lead to browning in apple peel due to changes in microenvironment, destruction of cell structure, decrease in flavonoids, and increase in triterpenoids.

Summary: The study identified MdMYB90-like as a key regulatory gene in a mutant apple with increased anthocyanin content in the skin, by directly activating anthocyanin biosynthesis genes and other transcription factors. This increased expression of MdMYB90-like was linked to reduced DNA methylation levels in the promoter regions, potentially explaining the enhanced coloration in the mutant.

Summary: The butanol fraction of apple leaves (BLE) exhibited gastro-protective and healing effects against indomethacin-induced gastric ulcers in rats. It reduced oxidative stress, inflammatory cytokines, and COX-2 expression and increased mucoglycoproteins and HSP70 expression. These effects are likely due to the presence of phytoconstituents.

Summary: Malic acid is a major organic acid in apples and plays an important role in determining fruit quality. A candidate gene, MdMa1, was identified in the Ma locus, which is a major quantitative trait locus for apple fruit acidity. Another gene, MdMYB21, was also found to be associated with malic acid. MdMYB21 negatively regulates malic acid accumulation and is directly involved in the expression of MdMa1.

Summary: The study investigated the potential role of MAPK in light-induced anthocyanin accumulation in apple peels, finding that MdMPK4 proteins phosphorylate MdMYB1 to increase its stability under light conditions. Light-induced anthocyanin accumulation relies on MdMPK4 kinase activity, which is essential for maximizing MdMYB1 activity. Based on the results, a potential biotechnological strategy for increasing fruit anthocyanin content via light induction is suggested.

Summary: The study successfully applied different spectroscopic techniques and modeling methods to trace the proportions of apple varieties in purees and predict the quality characteristics. The PLS models performed well in estimating the proportions of apple cultivars in mixtures, while MIRS technique was effective in predicting the quality of final purees based on spectral data of composed cultivars.

Summary: Rootstock selection and crop load adjustment are crucial for apple orchard management. This study investigated the effects of different rootstocks and crop load levels on photosynthetic performance and carbohydrate accumulation in apple scions. The results showed that 'G.935' rootstock improved photosynthetic performance, and high crop load increased gas exchange. However, the influence of rootstocks on leaf-soluble sugars was not significant. Leaves from low-cropping trees had higher concentrations of fructose, glucose, and sorbitol. Therefore, careful selection of rootstocks and control of crop load are important for apple orchard management.

Summary: This research evaluated the horticultural performance of 'Buckeye Gala' apple scion grafted onto different rootstocks. The results showed that different rootstocks have significant impacts on tree size, yield, and fruit maturity. Considering the importance of rootstocks in fruit maturity and quality, it is crucial to take them into account when making management decisions in Western Maryland orchards.

Summary: In this study, apple cultivars were categorized based on their pollen tube growth performance, with 41 individuals divided into three subgroups using statistical analysis and a decision tree model for prediction. Thresholds were established from the decision tree to characterize new observations, demonstrating the effectiveness of the methods in a case study with 29 apple accessions.

Summary: This study evaluates the efficiency of different budburst inducers for apple trees and finds that garlic extract is not effective, but hydrogen cyanamide and Erger (R) are good alternatives. The biological method of single bud is not suitable for evaluating the efficiency of budburst inducers.
