Summary: In this study, 19 PpLhc genes were identified in the peach genome database, and they were unevenly distributed on all chromosomes. Phylogenetic analysis showed that PpLhc proteins could be divided into three major subfamilies with different exon-intron structures but shared similar conserved motifs. The promoter regions of all PpLhc genes contained 17 different cis-regulatory elements, which were classified into three categories: plant growth and development, stress response, and phytohormone response. Transcriptomic data analysis and RT-qPCR results suggested the crucial roles of Lhc genes in regulating plant tolerance to drought stress.

Summary: Water deficit in young fruit trees can decrease growth and orchard productivity. The use of exogenous silicon (Si) has shown potential in mitigating water deficit, but its role in fruit trees remains largely unknown. This study aimed to investigate the effect of Si applications on water status and gas exchange in young peach trees. Two experiments were conducted, with different water regimens and Si concentrations. Si applications at 10 or 20 mg/L improved water status without affecting gas exchange, while 40 mg/L reduced CO2 assimilation. Therefore, foliar application of Si could be a promising strategy to maintain water status and enhance recovery from water deficit in non-irrigated orchards.

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: The production of peaches in South Asian countries is threatened by biotic stresses, especially nematodes. Chemical control methods have limited efficacy against root-knot nematodes, which have emerged as the most damaging ones. A study evaluated the efficacy of four biocontrol agents against Meloidogyne javanica on peach trees. The results showed that two biocontrol agents significantly reduced the number of galls, while all agents effectively reduced egg masses and reproductive factors. This suggests that biocontrol agents have the potential to replace or reduce the use of traditional chemicals for controlling root-knot nematodes.

Summary: Waterlogging, caused by climate change impacts, is a significant abiotic stress for plants. Peach trees are highly sensitive to hypoxia during waterlogging, leading to poor growth and economic losses. The molecular mechanism underlying the response of peach to waterlogging and reoxygenation is still unclear. In this study, the physiological and molecular responses of 3-week-old peach seedlings to waterlogging and recovery conditions were comprehensively analyzed. The results suggest that glutathione, primary sugars, and hormone biosynthesis and signaling may play crucial roles in the plant's response to waterlogging. This work provides valuable insights into the gene regulatory networks and metabolites involved in waterlogging stress and recovery, which can aid in the control of waterlogging in peach cultivation.

Summary: In this study, the levels of various metals in coffee, tea, and herbal tea from different brands in the Iranian market were assessed. The results showed that the metal levels in coffee samples were similar among different trademarks of the same country, but significantly differed among brand names from different countries. Metal levels in tea samples differed significantly between domestic and imported products, while no significant variations were observed among different trademarks of similar countries. Metal levels in herbal tea samples did not vary significantly among different trademarks. Risk assessment indicated no risk for non-carcinogenic metals, but probabilistic assessment showed a risk. The carcinogenic metals arsenic (As) and nickel (Ni) had a medium level of estimated lifetime cancer risk (ILCR), while lead (Pb) did not pose a cancer risk. Sensitivity analysis revealed that metal concentration had the most significant effect on non-carcinogenic and carcinogenic risks.
