Summary: This study found that applying 1.0 mu L L-1 1-methylcyclopropene (1-MCP) to 'Yuluxiang' pear can delay the appearance of greasy coating and yellowing on the peel. 1-MCP treatment maintains higher fruit firmness and chlorophyll content, decreases respiration rate, postpones the peak of ethylene production rate, and reduces the greasiness index of the peel. Furthermore, 1-MCP also decreases the expression of genes related to ethylene synthesis and signal transduction, chlorophyll breakdown, and wax accumulation.

Summary: The effect of the phytohormone ethylene on the quality deterioration of fresh-cut Chinese water chestnuts caused by mechanical damage has been investigated. The treatment with ethephon (ET) was found to be the most effective in maintaining the visual quality of the fresh-cut Chinese water chestnuts. Additionally, the combined treatment of 1-methylcyclopropene (1-MCP) preceding ET treatment was able to inhibit the senescence of the fresh-cut Chinese water chestnuts and showed potential for quality control.

Summary: The study in Caenorhabditis elegans reveals the role and regulation of heat shock transcription factor HSF-1 in germline development, showing that heat stress only induces the canonical heat shock response in a subset of germ cells, while insulin/IGF-1 signaling activates HSF-1 in germ cells through signaling pathways in somatic cells. This non-cell-autonomous mechanism links nutrient-sensing insulin/IGF-1 signaling to HSF-1 activation to support homeostasis in rapid germline growth.

Summary: The Caenorhabditis elegans genome encodes nineteen functional Argonaute proteins, among which CSR-1 is essential under normal laboratory conditions. However, the gene locus encodes two isoforms, CSR-1a and CSR-1b, with different tissue-specific functions. The isoforms interact with partly overlapping sets of 22G-RNAs, emphasizing the importance of studying each AGO isoform independently.

Summary: Research has found that there are two different isoforms of the Tet1 gene in the adult mouse brain, with Tet1(S) being highly enriched in neurons and Tet1(FL) more abundant in glia, suggesting their roles are at least partially cell type-specific. Using neuron-specific molecular tools, it has been demonstrated that each Tet1 isoform serves a distinct role in the mammalian brain.

Summary: This study identified a dual regulatory mechanism for the utilization of 2-aminoethylphosphonate (2AEP) in pseudomonads, where utilization only occurs when carbon (C), nitrogen (N), or phosphorus (P) are depleted. The presence of 2AEP is necessary for full gene expression, indicating substrate inducibility. This is the first study to identify coordination between global stress response and substrate-specific regulators in phosphonate metabolism.

Summary: Diet plays a crucial role in non-communicable diseases, and food production is a major contributor to environmental degradation and greenhouse gas emissions. However, changing people's food choices to prioritize health and the environment is challenging due to factors like affordability, convenience, and taste. The 'Raising the Pulse' project aims to revolutionize the nutritional value of UK consumers' diets while promoting improved health and sustainability in the UK food system. This will be achieved through collaboration with key stakeholders to implement optimized faba bean production systems, develop palatable faba bean flours, and create 'Raising the Pulse' food products with enhanced nutritional and environmental benefits. Consumer insights and interventions will be used to evaluate the impact and acceptability of pulse-based foods on diet quality, satiety, nutritional knowledge, and market potential. Furthermore, a system model will be developed to predict the effects of substituting less nutritious and environmentally unsustainable ingredients with pulses on land use, environment, business viability, nutrition, and human health. By addressing government health and sustainability priorities, this project will contribute to policy-driven solutions with significant economic impacts on the supply chain and transform sustainable food systems to improve consumer diet quality, health, and the environment.

Summary: Oilseed rape is an important oil crop worldwide, but the genetic mechanisms of its adaptations to low phosphate stress are largely unknown. This study identified 68 SNPs significantly associated with seed yield under low phosphate availability and 7 SNPs significantly associated with phosphorus efficiency coefficient. Two SNPs were co-detected in two trials and were associated with BnaC07.ARF9 and BnaC09.PHT1;2 genes. The gene expression levels of BnaC07.ARF9 and BnaC09.PHT1;2 were significantly correlated with seed yield under low phosphate conditions. A large number of genes related to phosphate uptake, transport, and utilization were also detected. These findings provide insights into breeding high phosphorous efficiency varieties in oilseed rape.

Summary: Phosphorus (P) is essential for plant growth and development, and inositol pyrophosphates (PP-InsPs) serve as important nutrient messengers in signaling P status. This review highlights the biosynthesis of PP-InsPs and their regulation by plant P status, the impact of PP-InsPs on SPX domain-containing proteins in P status signaling, the effects of inositol pyrophosphates on auxin and jasmonate signaling, and the potential crosstalk between P status signaling and phytohormone signaling mediated by inositol pyrophosphates. The interaction between inositol pyrophosphates and their binding proteins is crucial for plant P status and developmental responses to different P supply.

Summary: The study identified a genetic locus on chromosome 7 in tomato that controls both vegetative and reproductive organ size, with alleles from wild species leading to lower cell number and reduced size of leaves, flowers, and fruits in introgression lines. The findings suggest that selection for large fruit during domestication also influences leaf size by altering cell division, potentially allowing for fine-tuning of parameters important for crop adaptation.

Summary: Soil compaction due to mechanized farming operations can significantly affect root and shoot traits, nutrient acquisition, and plant biomass accumulation of Brassica napus. Different cultivars of Brassica napus exhibited varying responses to soil compaction, with those having large root mechanical traits showing higher root cellulose and lignin concentrations, as well as increased root exudates secretion. Deep rooting in compacted soil enhanced nutrients acquisition and further biomass accumulation. Therefore, Brassica napus cultivars with large root mechanical traits, fine roots, and more root exudates are crucial for penetrating into deep soil layers in compacted soil.
