Detection of Ribosomal DNA Sites in Lentil and Chickpea by Fluorescent in Situ Hybridization

Detection of Ribosomal DNA Sites in Lentil and Chickpea by Fluorescent in Situ Hybridization

S Abbo et al. Genome. .

Abstract

Hybridization sites of an rDNA probe coding for the 18S, 5.8S, and 26S genes were detected on lentil and chickpea somatic chromosomes using fluorescent in situ hybridization. One pair of hybridization sites was detected in cultivated lentil Lens culinaris L. and wild lentil L. orientalis (Boiss.) Hand.-Mazz., and in both the hybridization sites of the ribosomal probe correspond to the secondary constriction. In cultivated chickpea Cicer arietinum three pairs of rDNA sites were detected and in the wild C. reticulatum two pairs were detected. The karyotypic relationship between the cultivated C. arietinum and its wild progenitor C. reticulatum is discussed.
