RESUMO

This study analyzes Paraguay's biotechnology regulatory framework and its alignment with international standards amid biotechnological advancements. It also identifies areas of improvement for enhancing framework effectiveness. Through this work, we aim to provide a resource for policymakers, stakeholders, and researchers navigating Paraguay's biotechnology regulation.

RESUMO

Paraguay is integrated into the world mainly through its agricultural activity. The population's perception of genetically engineered crops is relevant to design communication strategies that convey the advantages and limitations of the various technologies used in the country. We aimed to know the perception of the population of four Departments of the country where such crops are grown through a survey, which revealed a low level of knowledge about genetically engineered crops in general, and specifically about the effects of genetically engineered crops on production, nutrition, and the environment. Respondents expressed a willingness to receive information on genetically engineered crops, in particular from the National Government and the Health Sector.

RESUMO

Agricultural biotechnology was first regulated in Paraguay in 1997. The first update to the country's regulatory framework came in 2012, motivated by the need to keep up with current technologies. As part of this process, in late 2012, the Paraguayan Ministry of Agriculture (MAG) joined the Partnership for Biosafety Risk Assessment and Regulation, led by ILSI Research Foundation. The purpose of the program was the development of capacity building activities. As a result, the regulatory authorities in Paraguay incorporated the problem formulation approach to environmental risk assessment into their regulatory processes, leading to improved efficiency, with more timely decisions. Shifting to a problem formulation-based decision-making system was not straightforward, since practice and experience are always required to make professional risk assessors. Despite the continuity of approvals, there was a lag in the response time reflected in the number of events approved. During 2019, a simplified approval procedure for events that have been assessed by sound and experienced regulatory systems was introduced. Acceptance of third-country assessments can allow regulatory systems to make better use of their human, financial, and institutional resources, and stimulate inter-agency cooperation. In this work we aim to present the recent evolution of the regulatory system in Paraguay toward the establishment of a simplified procedure for GE crops that have been already assessed by sound and experienced regulatory systems, taking into account several scientific criteria. Concepts such as the familiarity, history of safe use, substantial equivalence, transportability, problem formulation, and the use of the consensus documents, developed by Organization for Economic Co-operation and Development (OECD), Food and Agriculture Organization of the United Nations (FAO), World Health Organization (WHO) and other institutions, favors the acceptance of decision documents issued by third countries. This requires the commitment of governments to support the stability of the institutions responsible for the regulatory implementation and also encourages countries to put work into the preparation and publication of decision documents, which are the basis for the commercialization of GE events.

RESUMO

La función original de los sistemas CRISPR/Cas es destruir el DNA de virus bacterianos. Este sistema ha evolucionado para identificar y cortar secuencias de diferentes DNA de virus de DNA evitando la infección. En la célula, está compuesto de genes Cas que producen nucleasas guiadas por RNA capaces de cortar el DNA. Si el RNA guía encuentra DNA de un virus con el que se puede emparejar, recluta a la nucleasa Cas9 que lo corta. Este sistema es utilizado in vitro para editar genes basándose en la producción de rupturas de doble cadena y su posterior reparación. Actualmente existen varias plataformas para el diseño de RNAs guía, aunque también es posible realizarlo de forma manual. Los componentes del sistema son entregados a la célula mediante un plásmido o una ribonucleoproteína. En esta revisión nos centraremos en la función original de CRISPR/Cas en procariotas y en cómo los investigadores la han modificado para proporcionar nuevas técnicas de edición de genomas. Discutiremos sobre las ventajas de esta nueva técnica, las formas en que podemos utilizarla y algunas de las limitaciones que aún encontramos en su aplicación


The original function of CRISPR/Cas systems is to destroy the DNA of bacterial viruses. This system has evolved to identify sequences of different DNA viruses and cut them in order to avoid infection. In the cell, the system is made up of Cas genes which produce RNA-guided nucleases capable of cutting DNA. If the guide RNA finds viral DNA with which it can pair up, it recruits the Cas9 nuclease to cut it. This system is used in vitro for gene edition, relying on the production of double-strand breaks and their subsequent repair. Currently, there are several platforms for the design of the guide RNA, and it is also possible to design it manually. The components of the system can be delivered to the cell through a plasmid or through a ribonucleoprotein. In this review we will focus on the original function of CRISPR/Cas in prokaryotes, and in how researchers have modified it in order to provide new genome editing techniques. We will discuss the advantages of this new technique, the ways in which it can be used, and some of the limitations found in its application
