A competing interest exists when your interpretation of data or presentation of information may be influenced by your personal or financial relationship with other people or organizations. Authors must disclose any financial competing interests; they should also reveal any non-financial competing interests that may cause them embarrassment were they to become public after the publication of the manuscript.
Authors are required to complete a declaration of competing interests. All competing interests that are declared will be listed at the end of published articles. Where an author gives no competing interests, the listing will read 'The author(s) declare that they have no competing interests'.
When completing your declaration, please consider the following questions:
Financial competing interests

If a language editor has made significant revision of the manuscript, we recommend that you acknowledge the editor by name, where possible. The role of a scientific (medical) writer must be included in the acknowledgements section, including their source(s) of funding. We suggest wording such as 'We thank Jane Doe who provided medical writing services on behalf of XYZ Pharmaceuticals Ltd.'
Authors should obtain permission to acknowledge from all those mentioned in the Acknowledgements section.
Endnotes should be designated within the text using a superscript lowercase letter and all notes (along with their corresponding letter) should be included in the Endnotes section. Please format this section in a paragraph rather than a list.
Literature citations in the text should indicate the author's surname with the year of publication in parentheses, e.g. Carlin (1992); Brooks and Carlin (1992).
If there are more than two authors, only the first should be named, followed by "et al."
References at the end of the paper should be listed in alphabetical order by the first author's name.
If there is more than one work by the same author or team of authors in the same year, a, b, etc. is added to the year both in the text and in the list of references.

PREPARING ILLUSTRATIONS AND FIGURES
Illustrations should be provided as separate files, not embedded in the text file.
Each figure should include a single illustration and should fit on a single page in portrait format.
If a figure consists of separate parts, it is important that a single composite illustration file be submitted which contains all parts of the figure.
There is no charge for the use of color figures.
The following file formats can be accepted:
� PDF (preferred format for diagrams)
� DOCX/DOC (single page only)
� PPTX/PPT (single slide only)
� PNG (preferred format for photos or images)
Progress in Biology will edit all figures supplied by the author. For this reason it is especially important that authors should supply figures in vector form, to facilitate such editing.
The legends should be included in the main manuscript text file at the end of the document, rather than being a part of the figure file.
For each figure, the following information should be provided: Figure number (in sequence, using Arabic numerals - i.e. Figure 1, 2, 3 etc); short title of figure (maximum 15 words); detailed legend, up to 300 words.
Please note that it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures or tables that have previously been published elsewhere.
Each table should be numbered and cited in sequence using Arabic numerals (i.e. Table 1, 2, 3 etc.).
Tables should also have a title (above the table) that summarizes the whole table; it should be no longer than 15 words. Detailed legends may then follow, but they should be concise.
Tables should always be cited in text in consecutive numerical order. Smaller tables considered to be integral to the manuscript can be pasted into the end of the document text file, in A4 portrait or landscape format.
These will be typeset and displayed in the final published form of the article. Such tables should be formatted using the 'Table object' in a word processing program to ensure that columns of data are kept aligned when the file is sent electronically for review; this will not always be the case if columns are generated by simply using tabs to separate text. Columns and rows of data should be made visibly distinct by ensuring that the borders of each cell display as black lines. Commas should not be used to indicate numerical values. Color and shading may not be used; parts of the table can be highlighted using symbols or bold text, the meaning of which should be explained in a table legend.
Tables should not be embedded as figures or spreadsheet files. Larger datasets or tables too wide for a landscape page can be uploaded separately as additional files.
Additional files will not be displayed in the final, laid-out PDF of the article, but a link will be provided to the files as supplied by the author.
Tabular data provided as additional files can be uploaded as an Excel spreadsheet (.xls ) or comma separated values (.csv).
As with all files, please use the standard file extensions
