The Molecular Cytogenetic Characterization of Pistachio (Pistacia vera L.) Suggests the Arrest of Recombination in the Largest Heteropycnotic Pair HC1
Fig 3
Karyotype root-tip metaphase chromosomes of P. vera (n = 15) stained with DAPI (A) showing two larger chromosomes (designated HC1) that are strongly heterochromatic. In situ hybridization using ribosomal DNA probes (red, 45S rDNA, pink, 5S rDNA), PIVE-180 (green) (B), and PIVE-40 (yellow, C). Bar represents 2.5 μm.
