From: Isolation and characterization of chromosomal markers in Poa pratensis
FISH patterns of mitotic chromosomes of Poa pratensis cultivars probed for repetitive sequences: a1-a3 PpTR-1 (green) and 5S rDNA (red) in ‘Qinghai’; b1-b3 PpCR-1 (red) and PpTR-3 (green) in ‘Warrior’; c1-c3 PpCR-1 (red) and 45S rDNA (green) in ‘Park’; d1-d3 PpTR-3 (green) and 5S rDNA (red) in ‘Kentucky’. Arrows in b3 indicates chromosomes without PpCR-1 sites. Arrows in d2 and d3 indicate the weak hybridization signals. Scale bar =10 μm
