The extent of intra-individual and intra-species heterogeneity in the nuclear rDNA internal transcribed spacer (ITS) was investigated among the 'Asiatic Vigna' species (subgenus Ceratotropis). High intra- and inter-individual ITS polymorphism was observed among Vigna radiata accessions, where multiple ITS length variants ranging from approximately 700 to approximately 770 bp were detected on PCR amplification. Subsequent analysis revealed that the variants are 'heteroduplex ITS fragments…

Molecular evolution of 5S rDNA region in Vigna subgenus Ceratotropis and its phylogenetic implications

The comparative analysis showed that 5S IGS sequences have better phylogenetic utility than chloroplast DNA sequences, such as atpB-rbcL and is comparable to ITS1 and ITS2 in this respect.

Phylogenetic analysis of subgenus vigna species using nuclear ribosomal RNA ITS: evidence of hybridization among Vigna unguiculata subspecies.

The results demonstrate differential evolution of ITS sequence among wild and cultivated forms of V. unguiculata and suggest that the rDNA units with the type-I ITS may have introgressed as a result of hybridization.

Molecular characterization of intergenic spacer region of 5S ribosomal RNA genes in subgenus Vigna: extensive hybridization among V. unguiculata subspecies

The results presented indicate that intraspecies hybridization might have resulted in the ‘horizontal transfer’ of 5S types among the V. unguiculata subspecies, while their maintenance could be due to a slow molecular drive.

Molecular cytogenetic characterisation and phylogenetic analysis of the seven cultivated Vigna species (Fabaceae).

F fluorochrome banding and cGISH are efficient tools for the phylogenetic analysis of Vigna species and Molecular phylogenetic trees showed that V. umbellata were the closest relatives, and V.Âsubterranea and V aconitifolia were relatively closely related.


The results indicate that NI 1637 is a hybrid between ssp.

Genetic Relationships among Aegilops L. and Triticum L. Species based on the Internal Transcribed Spacer Sequences of nrDNA (ITS)

The phylogenetic relationships among species were reconstructed using Unweighted Pair Group Mean Arithmetic average (UPGMA) and Neighbor-Joining (NJ) methods and the polymorphism in nucleotide sequences among 19 Aegilops L. and Triticum L. species was investigated.

Assessment of Genetic Diversity in Trigonella foenum-graecum Based on Nuclear Ribosomal DNA, Internal Transcribed Spacer and RAPD Analysis

Analysis of molecular variance indicated that a greater proportion of total genetic variation exists within population rather than among populations, and higher values of Nei’s gene diversity and Shannon Information Index and genetic distance analysis validate higher genetic diversity among Indian fenugreek varieties.

Comparative molecular cytogenetic characterization of five wild Vigna species (Fabaceae)

The combined data demonstrate that distinct genome differentiation has occurred among the five species during evolution and the phylogenetic relationships between the five wild species and related cultivated species of Vigna are discussed.

DNA Barcodes for the Assessment of Phylogenetic Relationships Based on CpDNA and NrDNA Regions in Vigna Species

The nuclear ribosomal internal transcribed spacer 2 (ITS2) region was the most useful as a single barcode and the four-barcode combinations that included ITS2 provided the best discriminatory power, and it is suggested that the ITS2 barcoding region should be used as a starting point to identify Vigna species.



Marked Intragenomic Heterogeneity and Geographical Differentiation of nrDNA ITS in Larixpotaninii (Pinaceae)

Nuclear ribosomal DNA (nrDNA) of gymnosperms, especially Pinaceae, is characterized by slow concerted evolution and exhibits substantial ITS-region length variation (975–3663 bp), in sharp contrast

Molecular Phylogeny of Genus Vigna Subgenus Ceratotropis Based on rDNA ITS and atpB-rbcL Intergenic Spacer of cpDNA Sequences

Data presented supports the view that section Angulares is the most recently diversified section in the subgenus Vigna, as inferred by short terminal branch lengths among the species of this section.

Molecular evolution and phylogenetic implications of internal transcribed spacer sequences of nuclear ribosomal DNA in the Phaseolus-Vigna complex.

The ITS sequences were shown to be useful for identifying wild progenitors of V. mungo, V. umbellata, and V. unguiculata and for clarifying taxonomy-related problems in many previously controversial cases, and this study affirms that V. angularis are the diploid progenitor of the only tetraploid species known in the genus.

Molecular evolution of the internal transcribed spacers (ITS1 and ITS2) and phylogenetic relationships among species of the family Cucurbitaceae.

Phylogenetic relationships of different members of the family Cucurbitaceae were estimated from sequences of the internal transcribed spacer (ITS1 and ITS2) regions of the nuclear ribosomal RNA

Intraspecific variation in the internal transcribed spacer region of rDNA in black gram (Vigna mungo (L.) Hepper)

There was no size variation in the ITS region of the diverse cultivars and other Vigna species studied, and no intraspecific variation was observed among widely distributed Indian cultivars of V. mungo var silvestris and the cultivated varieties studied.

Extensive Ribosomal DNA Genic Variation in the Columnar Cactus Lophocereus

Surprisingly, extensive paralogy was found not only in the ITS regions but also in the 5.8S coding regions in senita both within and between operons, suggesting that the second rDNA operon originated prior to the divergence of Lophocereus.

Documentation of reticulate evolution in peonies (Paeonia) using internal transcribed spacer sequences of nuclear ribosomal DNA: implications for biogeography and concerted evolution.

Reconstruction of reticulate evolution with sequence data provides gene records for distributional histories of some of the parental species and demonstrates that the sequence data could be highly informative and accurate for detecting hybridization.

Recent origin and phylogenetic utility of divergent ITS putative pseudogenes: a case study from Naucleeae (Rubiaceae).

These studies clearly show that ITS polymorphism may not necessarily mislead phylogenetic inference and, therefore, divergent putative pseudogenes can be useful for phylogenetic analyses, especially when no sequences of their functional counterparts are available.

Nuclear ribosomal DNA (nrDNA) concerted evolution in natural and artificial hybrids of Armeria (Plumbaginaceae)

These findings are relevant to interpreting phylogeographic patterns involving gene flow and are also consistent with the hypothesis of a hybrid origin of A. villosa ssp.

Inter simple sequence repeat analysis of genetic relationships in the genus Vigna

The utility of inter simple sequence repeat (ISSR) DNA polymorphisms to distinguish taxa within the genus Vignawas investigated and was not able to clearly differentiate subgeneric divisions within Vigna.
