The 16S rRNA gene has proved very useful in describing the diversity and characterization of marine microbial communities, particularly of uncultivated organisms. The development of new sequencing techniques has contributed to the exponential increase in the number of reported 16S rRNA sequences as barcodes for microorganisms, forcing a review of concepts and methods for the taxonomic classification of these organisms. Manipulation and analysis of large amounts of genetic information have prompted the development of specific databases, specialized algorithms, and computational tools to compare thousands of such sequences and make a taxonomic assignment. Complete 16S rRNA sequences are thus needed for accurate and reproducible taxonomy assignment in the study of marine bacterial communities.  Las nuevas tecnologías de secuenciación y capacidades analíticas han estimulado el estudio de las comunidades microbianas de ambientes específicos, lo cual ha permitido conocer la complejidad de estos sistemas. El gen ARNr 16S ha demostrado ser de gran utilidad para describir y caracterizar las comunidades microbianas marinas, especialmente los organismos no cultivados. Las nuevas técnicas de secuenciación han contribuido al incremento exponencial de registro de secuencias, aunque parciales, del ARNr 16S como elemento de código de barras para microorganismos. Consecuentemente, ha sido necesaria una revisión de conceptos y métodos de clasificación taxonómica para estos organismos. El manejo y análisis de una gran cantidad de información génica han impulsado el desarrollo de bases de datos específicas, algoritmos y herramientas computacionales especializadas para comparar miles de secuencias semejantes y hacer la asignación taxonómica. Por lo tanto, las secuencias completas del ARNr 16S son necesarias para una asignación taxonómica certera y reproducible en los estudios de comunidades microbianas marinas. 2015-12-18 2021-06-03T03:55:25Z 2021-06-03T03:55:25Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2492 10.7773/cm.v41i4.2492 https://hdl.handle.net/20.500.12930/7480 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2492/1574 Copyright (c) 2015 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 41 No. 4 (2015); 297-313 Ciencias Marinas; Vol. 41 Núm. 4 (2015); 297-313 2395-9053 0185-3880
