  1. 1See Figure 6 and Plant rDNA database - http://www.plantrdnadatabase.com[42].
  2. 2The gene copies were initially determined by slot blot hybridisation [43] and later adjusted by calculation from the NGS data [22] using a http://w3lamc.umbr.cas.cz/profrep/ server. For N. kawakamii and N. otophora the copies were determined based on Southern blot signals (Figure 5).
  3. 3Mean read-depth: the number of aligned reads divided by rDNA copy number.
