Molecular Cytogenetics of Pisum sativum L. Grown under Spaceflight-Related Stress

Figure 2

FISH-mapping of five different DNA repeated sequences on chromosomes of experimental and control P. sativum samples. Metaphase spreads of the F1-14 plant (a), F2-14 plant (b), F2-16 plant (c), F1-16 plant (d), control plant (e), F1-14 plant bearing translocation t(2;3) (f), and its karyogram (g) after FISH with 45S rDNA, 5S rDNA, PisTR-B/1, (AG)₁₂, and (GAA)₉. Arrows point to the chromosomal translocation. Heads of arrows point to (GAA)₉ sites on chromosomes 6 and 7. The correspondent probes and their pseudocolours are specified on the right. Bar: 5 μm.
