چکیده

Double-target fluorescent in situ hybridization (FISH) was used to determine the genomic distribution of ribosomal RNA genes in five Lupinus species: L. cosentinii (2n=32), L. pilosus (2n=42), L. angustifolius (2n=40), L. luteus (2n=52) and L. mutabilis (2n=48). 18S-25S rDNA and 5S rDNA were used as probes. Some interspecific variation was observed in the number and size of the 18S-25S rDNA loci. All the studied species had one chromosome pair carrying 5S rDNA.

Physical mapping of 5S and 18S-25S rDNA and repetitive DNA sequences in Aegilops umbellulata.

An accurate physical map of the location of the 5S and the 18S-5.8S-25S rRNA genes and a repetitive DNA sequence has been produced on Aegilops umbellulata Zhuk., (2n = 2x = 14) chromosomes by in situ hybridization. Chromosome morphology together with the hybridization pattern of pSc119.2, a DNA sequence from rye, allowed identification and discrimination of different chromosomes; pSc119.2 hybri...

In situ hybridization of 18S-5.8S-25S rDNA probes labeled with biotin or rhodamine and 5S rDNA probes labeled with digoxigenin was used to locate rDNA sites on root-tip metaphase chromosomes of Citrus sinensis L. (2n = 2x = 18), Poncirus trifoliata L. Raf. (2n = 2x = 18), and Citrus x Poncirus hybrids (2n = 2x = 18). Counterstaining with the fluorochromes chromomycin A3 and DAPI uniquely identi...

Hypostomus is a diverse group with unclear aspects regarding its biology, including the mechanisms that led to chromosome diversification within the group. Fluorescence in situ hybridization (FISH) with 5S and 18S rDNA probes was performed on ten Hypostomini species. Hypostomus faveolus, H. cochliodon, H. albopunctatus, H. aff. paulinus, and H. topavae had only one chromosome pair with 18S rDNA...

Agave Linnaeus, 1753 is endemic of America and is considered one of the most important crops in Mexico due to its key role in the country's economy. Cytogenetic analysis was carried out in Agave tequilana Weber, 1902 'Azul', Agave cupreata Trelease et Berger, 1915 and Agave angustifolia Haworth, 1812. The analysis showed that in all species the diploid chromosome number was 2n = 60, with bimoda...

Detection of Ribosomal Dna Sites in Chickpea (cicer Arietinum L.) and Mungbean (vigna Radiata (l.) Wiltzek) by Fluorescence in Situ Hybridization

Fluorescence in situ hybridization (FISH) technique was used to detect rDNA sites in chickpea and mungbean. In chickpea, the rDNA sites were detected on three pairs of chromosomes. Among these three pairs of chromosomes, one pair exhibited both 25S rDNA and 5S rDNA sites, while in case of other two pairs of chromosomes the 25S rDNA and 5S rDNA sites were located separately on separate pair of c...
