NCBI: REPOSITORY OVERVIEW AND BRIEF DESCRIPTION OF RESOURCES APPLICABLE TO THE STUDY OF PLANT GENETICS

The National Center for Biotechnology Information (NCBI) provides access to a set of computational resources that allow knowledge of biological systems; in addition, it includes various repositories of genomic and protein sequences, citations and scientific abstracts concerning the natural and health sciences. This work aimed to carry out a compilation of NCBI generalities, taking the following elements as the organizational basis of the document: the Entrez system, sources of information and updating of literature, including the taxonomy database, management of metadata and genetic expression, management of nucleotide sequence collections, processing of genomic and protein sequences. In addition, some useful tools applicable to the study of plant genetics that have supported the assembly of complete plant genomes are described, briefly discussing some research results derived from the use of bioinformatics resources such as genomic annotations, generation and organization of metadata, gene expression studies including transcriptomics, search for local and global nucleotide alignments, as well as structuring and three-dimensional modeling of proteins, among others.

Automated summary

The National Center for Biotechnology Information (NCBI) provides computational resources and repositories for genomic and protein sequences, citations, and scientific abstracts. This study compiles an overview of NCBI, focusing on the Entrez system, information sources, literature updates, taxonomy database, metadata management, genetic expression, nucleotide sequences, and genomic and protein processing. It also discusses useful tools and research results in plant genetics, including genomic annotations, metadata organization, transcriptomics, nucleotide alignments, and protein modeling.
