| Abstract: | Repetitive DNA sequences with variability in copy number or/and sequence polymorphism can be employed as useful molecular markers to study phylogenetics and identify species/chromosomes when combined with fluorescence in situ hybridization(FISH).Cucumis sativus has three variants,Cucumis sativus L.var.sativus,Cucumis sativus L.var.hardwickii and Cucumis sativus L.var.xishuangbannesis.The phylogenetics among these three variants has not been well explored using cytological landmarks.Here,we concentrate on th... |
