Jaggi K, Krak K, Storchova H, Mandak B, Marcheschi A, Belyayev A, et al.
Plant Genome . 2025 Feb; 18(1):e70010. PMID: 40018873
The genus Chenopodium L. is characterized by its wide geographic distribution and ecological adaptability. Species such as quinoa (Chenopodium quinoa Willd.) have served as domesticated staple crops for centuries. Wild...

Belyayev A, de la Pena B, Corrales S, Low S, Frejova B, Sejfova Z, et al.
Mob DNA . 2024 Nov; 15(1):26. PMID: 39548580
Background: The centromere is one of the key regions of the eukaryotic chromosome. While maintaining its function, centromeric DNA may differ among closely related species. Here, we explored the composition...

Belyayev A, Kalendar R, Josefiova J, Pastova L, Habibi F, Mahelka V, et al.
BMC Genomics . 2023 Sep; 24(1):572. PMID: 37752451
Background: Telomeres are the nucleoprotein complexes that physically cap the ends of eukaryotic chromosomes. Most plants possess Arabidopsis-type telomere sequences (TSs). In addition to terminal TSs, more diverse interstitial TSs...

Chumova Z, Belyayev A, Mandakova T, Zeisek V, Hodkova E, Semberova K, et al.
Front Plant Sci . 2022 Oct; 13:982852. PMID: 36247607
Non-coding repetitive DNA (repeatome) is an active part of the nuclear genome, involved in its structure, evolution and function. It is dominated by transposable elements (TEs) and satellite DNA and...

Belyayev A, Josefiova J, Jandova M, Kalendar R, Mahelka V, Mandak B, et al.
Mob DNA . 2022 Apr; 13(1):8. PMID: 35379321
Background: CACTA transposable elements (TEs) comprise one of the most abundant superfamilies of Class 2 (cut-and-paste) transposons. Over recent decades, CACTA elements were widely identified in species from the plant,...

Belyayev A, Jandova M, Josefiova J, Kalendar R, Mahelka V, Mandak B, et al.
PLoS One . 2020 Oct; 15(10):e0241206. PMID: 33108401
Satellite DNA (satDNA) is one of the major fractions of the eukaryotic nuclear genome. Highly variable satDNA is involved in various genome functions, and a clear link between satellites and...

Belyayev A, Josefiova J, Jandova M, Mahelka V, Krak K, Mandak B
Mob DNA . 2020 Jul; 11:20. PMID: 32607133
Extensive and complex links exist between transposable elements (TEs) and satellite DNA (satDNA), which are the two largest fractions of eukaryotic genome. These relationships have a crucial effect on genome...

Kalendar R, Raskina O, Belyayev A, Schulman A
Int J Mol Sci . 2020 Apr; 21(8). PMID: 32331257
Retrotransposable elements are widely distributed and diverse in eukaryotes. Their copy number increases through reverse-transcription-mediated propagation, while they can be lost through recombinational processes, generating genomic rearrangements. We previously identified...

Chrtek J, Mraz P, Belyayev A, Pastova L, Mrazova V, Caklova P, et al.
Am J Bot . 2020 Jan; 107(1):66-90. PMID: 31903548
Premise: The origin of allopolyploids is believed to shape their evolutionary potential, ecology, and geographical ranges. Morphologically distinct apomictic types sharing the same parental species belong to the most challenging...

Pastova L, Belyayev A, Mahelka V
BMC Plant Biol . 2019 Jun; 19(1):230. PMID: 31151385
Background: Interspecific hybridisation resulting in polyploidy is one of the major driving forces in plant evolution. Here, we present data from the molecular cytogenetic analysis of three cytotypes of Elytrigia...
