Hybrid Origin of × (Poaceae) as Revealed by Analysis of the Internal Transcribed Spacer ITS1 and L Sequences.

× is a presumed hybrid of and . This article investigates the hybrid origin and genome composition of this species. These plants are sterile, do not undergo pollination, and do not produce seeds; occasionally, underdeveloped stamens containing abortive pollen grains form in individual spikelets.

Genetic Diversity of the Species of the Genus P.Beauv. (Poaceae) Based on the Analysis of the ITS Region: Polymorphism Proves Distant Hybridization.

The species of the genus are difficult for identification, and the genus is difficult for taxonomic treatment. The regions of 35S rRNA genes were studied for the species of the genus of different geographical origin with a method of sequencing by Sanger (ITS1-5.8S rRNA gene-ITS2, 14 species) and with a method of a locus-specific next-generation sequencing (NGS) on the Illumina platform (ITS1-5.

Genome Variability in Artificial Allopolyploid Hybrids of L. and Balansa ex Coss. et Durieu Based on Marker Sequences of Satellite DNA and the ITS1-5.8S rDNA Region.

Artificial hybrids between cultivated species and wild that possess genes for resistance to biotic and abiotic stresses can be important for oat breeding. For the first time, a comprehensive study of genomes of artificial fertile hybrids × and their parental species was carried out based on the chromosome FISH mapping of satellite DNA sequences (satDNAs) and also analysis of intragenomic polymorphism in the 18S-ITS1-5.8S rDNA region, using NGS data.

Hybridization in the Subtribe Alopecurinae Dumort. (Poaceae) According to Molecular Phylogenetic Analysis: Different Ploidy Level Tells Different Origin of the Groups.

We performed next-generation sequencing of the 18S rDNA-ITS1-5.8S rDNA region along with traditional Sanger sequencing of L, K, F, and ITS1-5.8S rDNA-ITS2 to clarify the hybridization pattern in the subtribe Alopecurinae and in the genus in particular.

The application of Vavilov's approaches to the phylogeny and evolution of cultivated species of the genus Avena L.

The central problem that Vavilov was investigating was the overall concept of global plant genetic resources. The theoretical basis of this concept consisted of the law of homologous series in variation, research on the problem of species as a system, botanical and geographical bases of plant breeding, and the key theory of the centers of origin of cultivated plants. The VIR global collection of plant genetic resources collected by Vavilov and his associates from all over the world reflects the fullness of botanical, morphological and genetic diversity, and can be used for historical, evolutionary, phylogenetic and applied breeding research aimed at unlocking the potential of all the collection material.

Origin of the Rare Hybrid Genus × Tzvelev () According to Molecular Phylogenetic Data.

In our article, we analyzed new data on the origin of the hybrid genus ×. According to the morphological criteria × is a hybrid between s. l.

New Insights into the Genomic Structure of L.: Comparison of the Divergence of A-Genome and One C-Genome Oat Species.

We used next-generation sequencing analysis of the 3′-part of 18S rDNA, ITS1, and a 5′-part of the 5.8S rDNA region to understand genetic variation among seven diploid A-genome Avena species. We used 4−49 accessions per species that represented the As genome (A.

Intragenomic Polymorphism of the ITS 1 Region of 35S rRNA Gene in the Group of Grasses with Two-Chromosome Species: Different Genome Composition in Closely Related Zingeria Species.

Zingeria (Poaceae) is a small genus that includes Z. biebersteiniana, a diploid species with the lowest chromosome number known in plants (2n = 4) as well as hexaploid Z. kochii and tetraploid Z.
