B Publications in Genomics of the Top 40 Most-Cultivated Crops The 40 most-cultivated species were found by searching the Food and Agri- culture Organization of the United Nations’ FAOSTAT agricultural database of primary crops by area harvested. Model species are provided as references. For each species, the Web of Science, a database of about 8,700 journals, was queried for articles with the species name or common name in the title (ti=common name or ti=species name). The common name in plural and singular forms (for example, orange and oranges) and common names that can be compound words or two words (for example, chick pea and chickpea) were all used in the search. To nar- row down the list of articles to those relevant to genomics, only the articles that include either genomics, genomic, sequencing, or sequence as a topic are included (tc=genome or tc=genomics or tc=sequencing or tc=sequence).
