Exactly 2 years ago, PLoS ONE published this superb article (Fahlgren N, et al., 2007 High-throughput sequencing of Arabidopsis microRNAs: Evidence for frequent birth and death of MIRNA genes. PLoS ONE 2: e219), a citation classic. Thanks to its being published via Open Access, today it crossed the landmark of one hundred citations in Google Scholar. The paper thus became one of the star articles of PLoS series and the first one from PLoS ONE to log 3 digit citations in a record time of 2 years. The article was also evaluated in F1000 Biology and its corresponding author interviewed at PLoS blog.
