Fig. 2From: Satellite DNA in Paphiopedilum subgenus Parvisepalum as revealed by high-throughput sequencing and fluorescent in situ hybridizationFluorescent in situ hybridization (FISH) of root tip metaphase chromosomes with the SatA, 45S (green) and 5S (white) rDNA probes, counterstained with DAPI (blue): (a) P. concolor (subgenus Brachypetalum), (b) P. villosum (section Paphiopedilum), (c) P. rothschildianum (section Coryopedilum), (d) P. lowii (section Pardalopetalum), (e) P. appletonianum (section Barbata), and (f) P. primulinum (section Cochlopetalum). The absence of FISH signals confirms that SatA is indeed specific to subgenus Parvisepalum. Bar = 10 μmBack to article page
