    A Recipe for Success: Three Key Strategies Used by Aphids and Pseudomonas syringae to Colonize the Phyllosphere
    (Springer, 2023-01) Silva-Sanzana, Christian; Gangas, Maria Victoria; Zavala, Diego; Blanco-Herrera, Francisca
    Aphids and Pseudomonas syringae are a permanent challenge for agriculture, causing severe losses to the crop industry worldwide. Despite the obvious phylogenetic distance between them, both have become predominant colonizers of the plant kingdom. In this study, we reviewed three key steps of spread and colonization that aphids and P. syringae have mastered to successfully colonize the phyllosphere. These steps involve (i) plant-to-plant movement for locating new nutritional sources, (ii) disruption and modification of the apoplast to facilitate nutrient acquisition, and (iii) suppression of host defenses through effector proteins. In addition, we will provide insights about the direct interaction between aphids and P. syringae and how this yet underrated phenomenon could bring new ecological implications for both organisms beyond their pathogenicity. © 2022, The Author(s).

    Draft Genome Sequence of Pseudomonas syringae RAYR-BL, a Strain Isolated from Natural Accessions of Arabidopsis thaliana Plants
    (American Society for Microbiology, 2022-01) Fuenzalida-Valdivia, Isabel; Gangas, Maria Victoria; Zavala, Diego; Herrera-Vásquez, Ariel; Roux, Fabrice; Meneses, Claudio; Blanco-Herrera, Francisca
    Here, we report the genome sequence of the P. syringae strain RAYR-BL, isolated from natural accessions of Arabidopsis plants. The draft genome sequence consists of 5.85 Mbp assembled in 110 contigs. The study of P. syringae RAYR-BL is a valuable tool to investigate molecular features of plant-pathogen interaction under environmental conditions. Copyright © 2022 Fuenzalida-Valdivia et al.
