Summary: This study evaluated the protective effect of the culture filtrate of the rhizobacterium Paenibacillus polymyxa strain SZYM against Zucchini yellow mosaic virus (ZYMV) infection in squash plants. The results showed that the culture filtrate improved squash growth, reduced disease severity, and decreased virus accumulation. Additionally, the culture filtrate induced systemic resistance and enhanced the plant's defense against viral infection.

Summary: In this study, the accumulation of lignin and changes in the transcriptome of postharvested water bamboo shoots under cold storage were investigated. It was found that lignin significantly accumulated in the shoots and the major up-regulated genes were involved in phenylpropanoid biosynthesis, plant-pathogen interactions, and starch and sucrose metabolism. The MAPK signaling pathway and RBOH genes were also up-regulated. Inhibition of RBOH oxidase hindered lignin deposition and biosynthesis, while H2O2 enhanced these processes, indicating that lignification of water bamboo shoots is regulated by RBOH-mediated ROS signaling.

Summary: Photodynamic inactivation of microorganisms (aPDI) is an effective method to destroy antibiotic-resistant microbial isolates, but research on different photosensitizers, target microorganisms, and light delivery systems mostly shows efficacy in vitro models. Investigating different bacterial subpopulations' responses to aPDI is essential to identifying molecular features driving antimicrobial photodynamic inactivation effectiveness.

Summary: The phytohormone abscisic acid (ABA) and mitochondrial alternative oxidase (AOX) both contribute to drought stress responses in tomato. ABA regulates alternative respiration and increasing AOX enhances drought tolerance by reducing reactive oxygen species (ROS) accumulation. The transcription factor SlAREB1 directly activates the transcription of AOX1a and its silencing compromises ABA-induced alternative respiration, leading to decreased resistance to drought stress. These findings provide new insights into the role of AOX in ABA-mediated drought tolerance.

Summary: The study revealed that under waterlogging conditions, watermelon cultivar 'YL' exhibited higher expression of ClaAOX, which led to better photosynthesis and less oxidative damage compared to watermelon cultivar 'Zaojia8424'. Additionally, the alleviation of oxidative damage and promotion of photosynthesis in 'YL' were associated with increased levels of ascorbate, higher GSH/GSSG ratio, and enhanced activity of antioxidant enzymes, such as APX and CAT.

Summary: This study used RNA sequencing and weighted gene co-expression network analysis to identify hub genes associated with cold tolerance in H. virescens. The expression levels of these hub genes were significantly higher under low-temperature stress. Gene ontology and KEGG annotations indicated that these hub genes were mainly enriched in metabolism pathways. Additionally, protein interaction network and phylogenetic tree analysis revealed related species and ancestral branches. Therefore, this study provides methodology and guidance for researching cold tolerance genes in other herbage.

Summary: The innate immune system of plants plays a crucial role in plant-cell fate during interactions with pathogens, often leading to a hypersensitive reaction related to cell death and restricted pathogen growth. Plant mitochondria are essential for maintaining a balance between cell respiration and reactive oxygen species formation, with alternative oxidase playing a key role in metabolic homeostasis and minimizing production of reactive oxygen species. This alternative respiratory pathway and enzyme function in important cellular processes, such as programmed cell death and hypersensitive response.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This study evaluated a large set of blueberry cultivars to understand the relationship between mechanical texture and appearance characteristics at harvest and after storage, and tested multiple statistical models to predict shelf-life. The results showed that fruit characteristics measured at harvest or two weeks post-harvest can predict weight loss, texture change, and fruit wrinkling. These findings provide empirical data that blueberry breeders can use to select cultivars with extended shelf-life.

Summary: This study found that H2S treatment can delay the senescence process of postharvest pakchoi by regulating antioxidant system, endogenous H2S and NO metabolism. H2S increased the activities of antioxidant enzymes by up-regulating the expression of enzyme genes, reducing the accumulation of harmful substances. Furthermore, H2S increased the content of cysteine and nitrate in pakchoi by regulating the expression of related genes and enzyme activities, thus slowing down the senescence of pakchoi.
