Summary: In this study, the PpHY5 gene in peach was found to be involved in the regulation of the Cs trait. It interacts with the E3 ubiquitin ligase PpCOP1 and promotes the transcription of PpMYB10.1 through its partner PpBBX10. Silencing of PpHY5 leads to reduction in anthocyanin pigmentation, while overexpression results in anthocyanin accumulation.

Summary: Auxin and ethylene are critical for peach fruit ripening, with the ILR gene PpILR1 playing a key role in regulating this process through the interaction between the two phytohormones. PpILR1 acts as a transcriptional activator of PpACS1 and hydrolyzes auxin substrates to release free auxin, influencing ethylene and strigolactone-related phenotypes in transgenic tomato plants. These findings provide insights into the role of IAA-amino acid hydrolases in plants and their impact on fruit cultivation and storage.

Summary: Anthocyanin accumulation in the flesh of peach exhibits a spatial pattern, but the mechanism is still unknown. In this study, flavonoid metabolites, plant hormones, and transcriptome analyses were performed to investigate the regulation of anthocyanin accumulation in peach flesh. The results revealed the up-regulation of anthocyanin biosynthetic genes, transportation genes, and regulatory genes, as well as the enrichment and distribution of various hormones in peach flesh.

Summary: This study described previously undescribed peach flesh color patterns in commercial cultivars and investigated the genetic inheritance of red dots in the flesh (RDF) and red color around the stone (CAS). The findings will contribute to better characterization of peach plant materials and the development of a molecular marker system for selecting these traits.

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: This study focused on the variability of the PpSOC1 gene among 16 peach cultivars and its potential as a functional marker for endodormancy timing. Significant correlations were found between PpSOC1 alleles and various phenology phases, with the strongest correlation observed at the string stage, which marks the end of endodormancy. Cultivars with a specific allele reached the string stage significantly earlier than those with a different allele, making PpSOC1 screening a valuable tool in peach breeding.

Summary: This study reports the role of an elongated hypocotyl 5-homolog gene, PpHYH, in regulating anthocyanin pigmentation in peach fruit peel. Light is a key factor affecting anthocyanin accumulation in peach fruit peel. PpHYH activates the transcription of three PpMYB10 genes and interacts with a cofactor PpBBX4 encoding a B-BOX protein, leading to anthocyanin accumulation in the sun-exposed peel. However, a negative regulator, PpCOP1, represses the activity of PpHYH, resulting in failure of anthocyanin accumulation in the shaded peel.

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: Fruit load affects the photosynthetic characteristics and fruit quality of peach trees. When the fruit load is low, the photosynthetic rate and chlorophyll content decrease, while the soluble sugar and sugar alcohol content increase. The individual fruit quality, soluble solid content, sugar-to-acid ratio, soluble sugar, and sugar alcohol content also increase.

Summary: Peach and apricot, two economically important species in the Prunus genus, exhibit distinct carotenoid profiles. The β-carotene content is higher in mature apricot fruits, giving them an orange color, while peach fruits accumulate xanthophylls with a yellow color. Transcriptional analysis revealed that BCH1 gene expression is higher in peach, correlating with the carotenoid profiles. However, the enzymatic activity of BCH1 is similar in both species. Comparative analysis of the BCH1 gene promoters between peach and apricot provided insights into their promoter activity differences.

Summary: The study found that there are distinct differences in the ways Capataz and Beirao handle Cd at different concentrations. The Cd root retention in Capataz increased with external Cd concentration, while Beirao had higher Cd root retention compared to Capataz and was independent of Cd concentration. Additionally, the expression levels of genes related to Cd transport varied between the two rice accessions.

Summary: This paper introduces a method for confirming the natural origin of flavor compounds using the IRMS technique for delta C-13 measurements. The method involves the adsorption of volatile molecules in zeolite before EA-IRMS analysis, minimizing errors caused by the volatility of the analyzed structures. The study demonstrates the stable effect of this method during the analysis of molecules with varying levels of volatility and high repeatability of EA-IRMS data.

Summary: The use of S stable isotopes in studying S metabolism in plants is still limited, but this study reveals the potential of S-32/S-34 analysis in characterizing the metabolic and molecular processes involved in plant S nutrition and homeostasis. Fractionation against S-34 occurs during sulfate uptake, and S isotope separations among different S pools and organs are observed as a result of S isotope fractionation and mixing effects during sulfate assimilation and plant S partitioning.

Summary: The bidirectional fluxes of cadmium and calcium across the plasma membrane were compared in subapical maize root segments. Cadmium influx was characterized by a combination of a saturable rectangular hyperbola and a straight line, indicating multiple transport systems. Calcium influx was described by a simple Michaelis-Menten function. The addition of calcium reduced cadmium influx, suggesting competition between the two ions.

Summary: Water stress severely affects rice yield, making improving plant tolerance to water stress a priority in rice breeding programs. However, the complexity of seedling practices, water management systems, and growth stages where stress occurs makes it difficult to identify single ideotypes for overcoming drought in diverse cropping ecosystems. Genomics and biochemical knowledge can contribute to developing flexible rice ideotypes, and screening of wild rice accessions and cultivated rice germplasms has identified genes improving water stress resistance. New frontiers include the study of epigenetic control and favorable microbiota. Innovative breeding technologies are advancing the development of water stress-tolerant rice varieties.
