  1. # Highly conserved refers to miRNAs that are conserved in all three dicots (Arabidopsis, soybean and Populus) and three monocots (rice, maize and Brachypodium) whose genome sequences are available. Moderately conserved refers to miRNAs that only conserved in some of these plant species, but not in all the six plant species described above (miRBase 20.0, June 2013; http://www.mirbase.org).
  2. Represents miRNA families that were first detected in wheat in this study.
  3. Abundance reflected by normalised reads (reads per million of total miRNA reads, RPM).
  4. Logarithm of the fold change was calculated using log2, whereas the fold change is the ration of the abundance of a miRNA family in flag leave, 5-d seeds, 10-d seeds or 20-d seeds to the abundance of the same miRNA family in seedlings). "-" refers to no data.
