PLoS Biology Citation System

References must be listed at the end of the manuscript and numbered in the order that they appear in the text. In the text, citations should be indicated by the reference number in brackets. Journal name abbreviations should be those found in the NCBI databases. A number of reference software companies supply PLOS style files (e.g., Reference Manager, EndNote).

References should be formatted as follows:

  • Published papers. Hou WR, Hou YL, Wu GF, Song Y, Su XL, et al. (2011) cDNA, genomic sequence cloning and overexpression of ribosomal protein gene L9 (rpL9) of the giant panda (Ailuropoda melanoleuca). Genet Mol Res 10: 1576-1588.
    Note: Use of a DOI number for the full-text article is acceptable as an alternative to or in addition to traditional volume and page numbers.
  • Accepted, unpublished papers. Same as above, but “In press” appears instead of the page numbers.
