The classification codes below refer to subject headings assigned to abstracts in the Plant Science database. Many records include multiple classifications that address the various subject areas covered. Both the terms and codes appear in the Classification, CL=, field in an IDS record.
To find a suitable code(s) to use when searching Plant Science, browse the following list for relevant terms. The terms can also be used to search the classification field. When you have found a code(s) or term(s), you can search for these by entering them on the advanced form or in the 'any field' query box on the standard search form.
