Percent coverage representing the percentage of unigenes mapped in our transcriptome data that were expressed at four times during dormancy. Gene coverage is the percentage of a gene covered by reads. This value is the ratio of the number of bases in a gene covered by unique mapping reads to the total bases in that gene. The distribution of unique reads over different read abundance categories show similar patterns for all four RNA-Seq libraries.
