'Winter Long') revealed by C-banding, pachytene analysis, and RAPD-aided fluorescence in situ hybridization. PG - 534-40 AB - Using molecular cytogenetic DNA markers, C-banding, pachytene analysis, and fluorescence in situ hybridization (FISH), a high-resolution karyotype was established in the cucumber. C-banding showed distinct hetero chromatic bands on the pericentromeric, telomeric, and intercalary regions of the chromosomes. The C-banding patterns were also consistent with the morphology of 4'-6-diamino-2-phenylindole dihydrochloride (DAPI)-stained pachytene chromosomes. Two repetitive DNA fragments, CsRP1 and CsRP2, were obtained by PCR and localized on the mitotic metaphase and meiotic pachytene chromosomes. CsRP1 was detected on the pericentromeric heterochromatic regions of all chromosomes, except chromosome 1. CsRP2 was detected on 5 (chromosomes 1, 2, 3, 4, and 7) of 7 chromosomes. All homologous chromosome pairs could be distinguished by FISH using 2 RAPD markers. This is the first report on molecular karyotyping of mitotic and meiotic spreads of cucumber.
