Topics: Supplementary Content

Supplementary Content, also known as "Supplementary Material" is content which is supplementary to a document such as additional tables or figures. This content is usually made available online but not in print.

For example, a supplementary figure is available for article 961 from The Plant Journal. The graphic file is named "tpj_961_suppl_fsms1.gif" in accordance with the DTD 4 filenaming convention.

1. <relatedgroup>

Details of the external file are put in the relatedgroup element of the parent document (tpj_961.xml):

<relatedgroup>
<related relationship="child" type="object">
<file name="tpj_961_suppl_fsms1.gif" type="gif"/>
...
</related>
</relatedgroup>

2. <section>

An explanation of the supplementary content is included in a "supplementary_content" section of the parent document. In this case, the supplementary content is a figure, and so all that is needed in the the supplementary content section is an object element with the legend of the supplementary figure.

<p>(a) Schematic diagram of the region of <i>Arabidopsis</i> chromosome II containing 
the <i>AGT1</i> gene. Introns are depicted as lines and exons as boxes. The shaded areas of 
exons correspond to the portion of the <i>AGT1</i> cDNA used as a probe for DNA and RNA 
gel-blot analyses. The locations of predicted restriction sites are indicated.</p>
<p>(b) Approximately 10 &micro;g genomic <i>Arabidopsis</i> (ecotype C24) DNA was 
digested with the indicated enzymes, separated by electrophoresis, and transferred to a nylon 
membrane using standard procedures. The membrane was probed with a <sup>32</sup>P-labeled 
fragment of the <i>AGT1</i> cDNA. The sizes of known molecular weight markers (in kb) are 
indicated next to the autoradiograph.</p>
