A miniaturized, frugal RPA assay for genus-level detection of Paracoccidioides spp. in resource-limited endemic settings

Melina Noelia Lorenzini Campos, Raúl M. Acevedo, Gabriela Alejandra Massa, Laura Elena Valinotto et autres

BACKGROUND: Paracoccidioidomycosis (PCM) is a neglected systemic mycosis endemic to Latin America, where diagnosis is often delayed due to limited access to rapid, simple confirmatory testing tools in resource-limited settings. This gap creates a critical need for accessible detection methods of its …

Rejuvenation of Mature Ilex paraguariensis Plants Through Serial Rooted Cuttings: Exploring the Roles of miRNAs in Reversing Adult Phase, Promoting Root Formation, and Determining Root Structure

María J. Duarte, Raúl M. Acevedo, Nicolás Leandro Ortiz, Y Mayra et autres

In plants, the transition from the juvenile to adult stage involves physiological and anatomical changes initiated and partially controlled by evolutionarily conserved microRNAs. This process is of particular significance for the successful propagation of woody plant species that have transitioned to vegetative …

Yerba mate (Ilex paraguariensis) genome provides new insights into convergent evolution of caffeine biosynthesis

Federico A. Vignale, Andrea Hernandez Garcia, Carlos Pablo Modenutti, Ezequiel Jorge Sosa et autres

Yerba mate (YM, Ilex paraguariensis ) is an economically important crop marketed for the elaboration of mate, the third-most widely consumed caffeine-containing infusion worldwide. Here, we report the first genome assembly of this species, which has a total length of 1.06 Gb …

Applying nanopore sequencing technology in Paracoccidioides sp.: a high-quality DNA isolation method for next-generation genomic studies

Melina Noelia Lorenzini Campos, Ariel Amadío, José Matías Irazoqui, Raúl M. Acevedo et autres

Paracoccidioidomycosis is a severe systemic endemic mycosis caused by Paracoccidioides spp. which mainly affects individuals in Latin America. Progress in Paracoccidioides genomics has been slow, as evidenced by the incomplete reference databases available. Next-generation sequencing is a valuable tool for epidemiological surveillance …

Integrating Transcriptional, Metabolic, and Physiological Responses to Drought Stress in Ilex paraguariensis Roots

Edgardo H. Avico, Raúl M. Acevedo, María J. Duarte, Acácio Rodrigues Salvador et autres

The appearance of water stress episodes triggers leaf abscission and decreases Ilex paraguariensis yield. To explore the mechanisms that allow it to overcome dehydration, we investigated how the root gene expression varied between water-stressed and non-stressed plants and how the modulation of …

The Lambda Variant in Argentina: Analyzing the Evolution and Spread of SARS-CoV-2 Lineage C.37

Mercedes Soledad Nabaes Jodar, Carolina Torres, Laura Noelia Mojsiejczuk, Dolores Acuña et autres

The second wave of COVID-19 occurred in South America in early 2021 and was mainly driven by Gamma and Lambda variants. In this study, we aimed to describe the emergence and local genomic diversity of the SARS-CoV-2 Lambda variant in Argentina, from …

Transcriptome Dynamics of Rooting Zone and Leaves during In Vitro Adventitious Root Formation in Eucalyptus nitens

Paula G. Ayala, Raúl M. Acevedo, Claudia Verónica Luna, Máximo Rivarola et autres

Wood properties and agronomic traits associated with fast growth and frost tolerance make Eucalyptus nitens a valuable forest alternative. However, the rapid age-related decline in the adventitious root (AR) formation (herein, meaning induction, initiation, and expression stages) limits its propagation. We analyzed …
