“…Frontiers in Genetics frontiersin.org corroborate the view of independent events behind X 1 X 2 Y and XY 1 Y 2 origin in Harttia (Deon et al, 2022a;. We also show that chromosome 9 of H. carvalhoi, which has been fused to X chromosome in H. intermontana, is not involved in any other known sex chromosome system in Harttia, however, its propensity to fuse with other chromosomes has been recorded in H. dissidens.…”

“…In the present study, we mapped two WCP probes prepared from H. carvalhoi chromosomes, where the chromosomes X and 9 were involved in rearrangements leading to emergence of the XY 1 Y 2 sex chromosome system which is present in three Harttia species (Deon et al, 2022a). Both probes painted mostly entire chromosomes, thus pointing to preserved synteny blocks.…”

“…While H. carvalhoi and Harttia sp. 1 entirely share the identity of XY 1 Y 2 chromosomes, the same system in H. intermontana involves linkage group corresponding to chromosome 9 in H. carvalhoi, which implies two independent X-autosome fusions behind the origin of known Harttia XY 1 Y 2 sex chromosomes (Deon et al, 2022a).…”

“…1 (Centofante et al, 2006;Deon et al, 2020). Studies using whole chromosome painting (WCP) probes have recently demonstrated that both the XY and X 1 X 2 Y sex chromosome systems are homologous, while the XY 1 Y 2 system is formed by different linkage groups and thus has evolved independently (Deon et al, 2022a;. Intriguingly, the three XY 1 Y 2 -bearing species share the ancestral sex chromosomes but differ by autosomal additions.…”

The remarkable fish biodiversity encompasses also great sex chromosome variability. Harttia catfish belong to Neotropical models for karyotype and sex chromosome research. Some species possess one of the three male-heterogametic sex chromosome systems, XY, X1X2Y or XY1Y2, while other members of the genus have yet uncharacterized modes of sex determination. Particularly the XY1Y2 multiple sex chromosome system shows a relatively low incidence among vertebrates, and it has not been yet thoroughly investigated. Previous research suggested two independent X-autosome fusions in Harttia which led to the emergence of XY1Y2 sex chromosome system in three of its species. In this study, we investigated evolutionary trajectories of synteny blocks involved in this XY1Y2 system by probing six Harttia species with whole chromosome painting (WCP) probes derived from the X (HCA-X) and the chromosome 9 (HCA-9) of H. carvalhoi. We found that both painting probes hybridize to two distinct chromosome pairs in Amazonian species, whereas the HCA-9 probe paints three chromosome pairs in H. guianensis, endemic to Guyanese drainages. These findings demonstrate distinct evolutionary fates of mapped synteny blocks and thereby elevated karyotype dynamics in Harttia among the three evolutionary clades.

“…The lengths of the 5S rDNA sequence ranged from 48 bp (Turner et al 2005) to 854 bp (Liu et al 2017) because of its high copies and variations when searching for “5S rDNA” in the database Nucleotide of National Center for Biotechnology Information. Furthermore, the lengths of 5S rDNA as a FISH probe in the PubMed database from NCBI varied considerably: 41 bp (Luo et al 2017, Islam-Faridi et al 2020), 94 bp (Sergeeva et al 2017), 117 bp (Lukjanová et al 2023), 120 bp (Taketa et al 2001, Symonová et al 2017, Deon et al 2022, de Moraes et al 2023), 124 bp (Waminal et al 2018), 131 bp (Sergeeva et al 2017), 222 bp (Glugoski et al 2018), 285 bp (Röser et al 2001), 300 bp (Araya-Jaime et al 2022), 302 bp (Zhang et al2016), 303 bp (Mahelka et al 2013), 320 bp (Khensuwan et al 2023), 324 bp (Kamisugi et al 1994), 326 bp (Robledo and Seijo 2008), 329 bp (Röser et al 2001), 347 bp, ∼400 bp (Pedrosa et al 2002), 410 bp (Kovács et al 2023), 456 bp (Röser et al 2001), 468 bp, 473 bp, 477 bp, 496 bp (Martins et al 2000), 497 bp (Alexandrov et al 2022), 498 bp (Martins et al 2000), 500 bp (de Barros et al 2023), 556 bp (Gottlob-McHugh et al 1990), 596 bp (Joshi et al 2023), 702 bp (Glugoski et al 2018), 871 bp (Amarasinghe and Carlson 1988), and 1193 bp (Glugoski et al 2020).…”

5S rDNA is essential component of all cell types. A survey was conducted to study the 5S rDNA site number, position, and origin of signal pattern diversity in 64 plants using fluorescencein situhybridization. The species used for this experiment were chosen due to the discovery of karyotype rearrangement, and for species checked in which 5S rDNA has not yet been explored. The chromosome number was 14160, while the chromosome length was 0.636.88 m, with 37 plants (58%) had small chromosome (<3 m). The chromosome numbers of three species and 5S rDNA loci of 19 species have been reported for the first time. 5S rDNA was varied and abundant in signal site number (218), position (e.g., interstitial, distal, and proximal position, occasionally, outside chromosome), and even as intense (e.g., strong, weak, and slight). Our results exposed modifiability in the number and location of 5S rDNA in 33 plants and demonstrated an extensive stable number and location of 5S rDNA in 31 plants. The potential origin of signal pattern diversity was probably caused by chromosome rearrangement (e.g., deletion, duplication, inversion, translocation), polyploidization, self-incompatibility, and chromosome satellites. These data characterized the variability of 5S rDNA within the karyotypes of the 64 plants that exhibited massive chromosomal rearrangements and provided anchor points for genetic physical maps. These data prove the utility of the 5S rDNA oligonucleotide as a chromosome marker in identifying plant chromosomes. This method provides a basis for developing similar applications for cytogenetic analysis in other species.
