Previously, I described the compilation of a list of 517 contemporary Citation Classics in Plant Sciences (1992-2017) and revealed the authors, journals and organisations represented in these papers. Here I investigate the topics of these papers and try to predict some Citation Classics of the future.
The most common word in the titles of Citation Classics in Plant Sciences since 1992 was “plant”, which appeared in 38% of all titles. Other common words were “stress”, “response”, “gene”, “expression” and, of course, “arabidopsis”. The latter appeared in 11% of all titles. This is probably not surprising since this small, diploid, self-fertile plant has featured in an ever increasing number of publications in Plant Sciences between 1992 (1.9% of publications) and 2017 (18.9% of publications). Today, there seems to be almost as many publications in Plant Sciences on arabidopsis as on all the major crops of the world combined. But let me issue a word of caution for those of you now rushing to write an article entitled “The response of gene expression in arabidopsis plants to stress”; what was once a popular subject need not necessarily continue to be so. I tried to spot “food”, “security”, “climate” and “change” in the word cloud but couldn’t. Can you?
Tempted to write a review? Most of the contemporary Citation Classics I identified were either research articles (39.6%) or reviews (59.6%). When the relative proportion of each is plotted against year of publication, the proportion of research articles in the annual cohort is smaller at both the beginning and end of the time series. This suggests that a research article takes longer than a review to become a Citation Classic and its fame is shorter. Incidentally, as one might expect, since only 4% of all publications are reviews but more than 53% of Citation Classics are reviews, one can conclude that a review is more likely to become a Citation Classic than another type of article. Roughly 1 in 40 reviews will become Citation Classics compared to 1 in 800 research articles. So, if you want a Citation Classic in double quick time, with the greatest chance of success, you should write a popular review.
Finally, a prediction: I previously noted that the average number of Citation Classics was about 0.2% of the total number of papers published each year, which is one fifth of the 1% of papers that are designated “Highly Cited” on Web of Science. In order to predict the Citation Classics of the future one might look at an annual “Highly Cited” cohort and select the most cited papers. So, for example, if I were to predict 20 papers (11 reviews and 9 articles) from 2011 that could become Citation Classics by 2025 these would be, in order of their probable ascendance:

As you might observe, there are many popular authors, journals and research topics on this list that have featured in the three blog articles I have written for Botany One. Will the past predict the future? We shall have to wait and see.
