Summary: This study found that 1.0 g L-1 ferulic acid has significant induced resistance against blue mold of apples. It reduces lesion diameter and colony diameter, and enhances the activities and gene expressions of key enzymes involved in phenylpropanoid pathway and reactive oxygen species metabolism. This leads to the synthesis of antioxidants and secondary metabolites, thereby increasing disease resistance of apples.

Summary: The application of exogenous gamma-aminobutyric acid (GABA) can improve apple resistance to Marssonina apple blotch by reducing disease severity and maintaining normal photosynthesis. Additionally, GABA can induce the production of some disease-resistant substances in apple plants, such as salicylic acid and chitinase. Therefore, soil drenching of GABA may be a promising strategy to control the prevalence of Marssonina apple blotch.

Summary: In this study, ASM treatment increased H2O2 content and reduced antioxidant contents in apples, while EGTA + ASM treatment had the opposite effect. ASM treatment enhanced the activities of multiple enzymes but inhibited catalase activity, while EGTA + ASM treatment suppressed the activities of these enzymes. CDPKs play a crucial role in regulating ROS metabolism and inducing resistance in apples through ASM treatment.

Summary: To increase the production of delta-aminolevulinic acid (ALA) in cyanobacteria, the gamma-aminobutyric acid (GABA) shunt route was disrupted by inactivating the gene encoding glutamate decarboxylase. The resulting strain showed higher ALA levels when grown in the presence of levulinic acid (LA) and under salt and cold stress conditions. The highest ALA production was achieved by glucose induction and glutamate supplementation with LA. Increased levels of certain transcripts involved in ALA biosynthesis were observed in the disrupted strain under modified growth conditions.

Summary: GABA plays a crucial role in controlling neuronal excitability in vertebrate and invertebrate organisms, as well as in neurogenesis and synaptogenesis during embryonic development. In addition, GABA is implicated in various peripheral tissue disorders. The presence of GABA and its interactions with microbiota in freshwater polyps suggest a potential contribution to the evolution of nervous systems through microbe-neuronal interactions.

Summary: This study evaluated the sleep-improving effects of a GABA/5-HTP mixture in different generations and ages using Drosophila and mouse models. The mixture influenced nervous system-related genes, increased total sleep time, and reduced oxidative stress. The behavioral changes induced by the mixture were effective in eliminating ROS activity across generations and ages.

Summary: GABA and GSH play crucial roles in brain functioning and are involved in various neurodegenerative and psychiatric diseases. MRS is a unique non-invasive method to measure these neurometabolites, but motion stabilization is important, especially for specific patient groups. Spectral editing techniques are typically used for unambiguous detection of GABA and GSH, although they increase motion sensitivity.

Summary: Alcohol consumption is associated with health harms and governments worldwide are trying to reduce them. One approach is to reduce alcohol consumption, leading to the development of non-alcoholic drinks. However, non-alcoholic drinks do not provide the social interaction that alcohol does. Therefore, the alternative approach is to develop functional drinks that mimic the positive effects of alcohol without the harms.

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: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

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.

Summary: This study investigates the agroclimatic requirements of Prunus species cultivars growing in warm areas using Partial Least Squares regression. The findings reveal that the chilling and heat requirements of the cultivars appear discontinuous, with overlaps or transition periods between the two phases. The warm mean temperatures occurring during the chilling period are the main determinant of the flowering of the studied cultivars.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
