Authorship

Authorship credit should be based on (1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; (2) drafting the article or revising it critically for important intellectual content; (3) final approval of the version to be published; and (4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Each author should meet these four conditions. Individuals who provide assistance, e.g., supply strains or reagents or critique the paper, need not be listed as authors, but may be recognized in the Acknowledgments section.
