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.

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.

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.
