Abstract
Over the past decade, there has been a significant expansion in the development of plant-derived extracellular nanovesicles (EVs) as an effective drug delivery system for precision therapy. However, the lack of effective methods for the isolation and characterization of plant EVs hampers progress in the field. To solve a challenge related to systemic separation and characterization in the plant-derived EV field, herein, we report the development of a simple 3D inner filter-based method that allows the extraction of apoplastic fluid (AF) from blueberry, facilitating EV isolation as well as effective downstream applications. Class I chitinase (PR-3) was found in blueberry-derived EVs (BENVs). As Class I chitinase is expressed in a wide range of plants, it could serve as a universal marker for plant-derived EVs. Significantly, the BENVs exhibit not only higher drug loading capacity than that reported for other EVs but also possess the ability to modulate the release of the proinflammatory cytokine IL-8 and total glutathione in response to oxidative stress. Therefore, the BENV is a promising edible multifunctional nano-bio-platform for future immunomodulatory therapies.

Abstract
Many proteins secreted from plant cells into the surrounding extracellular space help maintain cell structure and regulate stress responses in the external environment. In this study, under Pi-replete and depleted conditions, 652 high-confidence secreted proteins were quantified from wild-type (WT) and PHOSPHATE RESPONSE 2 (OsPHR2)-overexpressing suspension-cultured cells (SCCs). These proteins were functionally grouped as phosphatases, signal transduction proteins, pathogen-related (PR) proteins, cell wall-remodeling proteins, and reactive oxygen species (ROS) metabolism proteins. Although PHOSPHATE RESPONSE (PHR) transcription factors regulate two-thirds of Pi-responsive genes at the transcriptional level, only 30.6% of the Pi-starvation-regulated secreted proteins showed significant changes in OsPHR2-overexpressing SCCs. The OsPHR2-dependent systemic Pi signaling pathway mainly regulates phosphatases and PR proteins, which are involved in the utilization of organophosphate, pathogen resistance, and colonization by rhizosphere microorganisms. The OsPHR2-independent local Pi signaling pathway, on the other hand, largely regulated ROS metabolism proteins, cell wall-remodeling proteins, and signal transduction proteins, which are involved in modifying cell wall structure and root architecture. The functions of differentially expressed secreted proteins between WT and OsPHR2-overexpressing plants under Pi-sufficient and Pi-deficient conditions were further confirmed by analysis of the acid phosphatase activity, ROS content, and cell wall composition.

Abstract
The Australian finger lime (Citrus australasica) is tolerant to Huanglongbing (HLB; Citrus greening). This species can be utilized to develop HLB tolerant citrus cultivars through conventional breeding and biotechnological approaches. In this report, we conducted a comprehensive analysis of transcriptomic data following a non-choice infection assay to understand the CaLas tolerance mechanisms in the finger lime. After filtering 3,768 differentially expressed genes (DEGs), 2,396 were downregulated and 1,372 were upregulated in CaLas-infected finger lime compared to CaLas-infected HLB-susceptible 'Valencia' sweet orange. Comparative analyses revealed several DEGs belonging to cell wall, β-glucanase, proteolysis, R genes, signaling, redox state, peroxidases, glutathione-S-transferase, secondary metabolites, and pathogenesis-related (PR) proteins categories. Our results indicate that the finger lime has evolved specific redox control systems to mitigate the reactive oxygen species and modulate the plant defense response. We also identified candidate genes responsible for the production of Cys-rich secretory proteins and Pathogenesis-related 1 (PR1-like) proteins that are highly upregulated in infected finger lime relative to noninfected and infected 'Valencia' sweet orange. Additionally, the anatomical analysis of phloem and stem tissues in finger lime and 'Valencia' suggested better regeneration of phloem tissues in finger lime in response to HLB infection. Analysis of callose formation following infection revealed a significant difference in the production of callose plugs between the stem phloem of CaLas+ 'Valencia' sweet orange and finger lime. Understanding the mechanism of resistance will help the scientific community design strategies to protect trees from CaLas infection and assist citrus breeders in developing durable HLB tolerant citrus varieties.
