Variations in 5S rDNAs in diploid and tetraploid offspring of red crucian carp × common carp

open access: yesBMC Genetics, 2017
Background The allotetraploid hybrid fish (4nAT) that was created in a previous study through an intergeneric cross between red crucian carp (Carassius auratus red var., ♀) and common carp (Cyprinus carpio L., ♂) provided an excellent platform to ...

Cytogenetic markers using single-sequence probes reveal chromosomal locations of tandemly repetitive genes in scleractinian coral Acropora pruinosa

open access: yesScientific Reports, 2021
The short and similar sized chromosomes of Acropora pose a challenge for karyotyping. Conventional methods, such as staining of heterochromatic regions, provide unclear banding patterns that hamper identification of such chromosomes.

Highly heterozygous Citrus changshan‐huyou Y. B. Chang originated from ancient hybridization between mandarin and pummelo and displayed distinct tissue‐specific allelic imbalance

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

Molecular structure of 5S rDNA of Mandragora autumnalis Bertol.

open access: yesVisnik ukrains'kogo tovaristva genetikiv i selekcioneriv, 2020
Aim. The region encoding 5S rRNA (5S rDNA) is present in the genome of all eukaryotic organisms. The 5S rDNA represents a universal model for studying the molecular evolution of the tandemly arranged repeated sequences. However, in the family Solanaceae, the molecular organization of 5S rDNA has been investigated only for few genera. In this regard, we

Gallic Acid‐Responsive microRNAs Reprogram Lignification During Drought Acclimation Process in Spearmint

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 4263-4281, June 2026.
ABSTRACT Mentha spicata L. (spearmint) is a high‐value aromatic and medicinal species, whose productivity is strongly affected by water deficit. Nevertheless, the molecular mechanisms underlying drought acclimation in this mint remain largely unexplored. Thus, here, we investigated the microRNA‐mediated regulatory processes triggered in M.

Ribosomal DNA localization on Lathyrus species chromosomes by FISH

open access: yesJournal of Genetic Engineering and Biotechnology, 2020
Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3219-3243, May 2026.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

FISH-mapping of the 5S rDNA locus in chili peppers (Capsicum-Solanaceae) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2016
ABSTRACT We present here the physical mapping of the 5S rDNA locus in six wild and five cultivated taxa of Capsicum by means of a genus-specific FISH probe. In all taxa, a single 5S locus per haploid genome that persistently mapped onto the short arm of a unique metacentric chromosome pair at intercalar position, was found.

Karyotyping of Brassica amphidiploids using 5S and 25S rDNA as chromosome markers [PDF]

open access: yesHereditas, 2002
Species of Brassica have small, morphologically similar chromosomes, which makes karyotyping difficult using conventional cytogenetic methods. Molecular cytogenetic methods, like fluorescence in situ hybridisation (FISH) have the potential to improve karyotyping through the use of chromosome- or genome-specific markers. Simultaneous application of more

Haplotype‐Resolved Genome Assembly and Population Genomics Reveal Evolutionary History and Agronomic Traits of Mulberry

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2105-2122, April 2026.
ABSTRACT Mulberry is a representative economic tree species valued for both poverty alleviation and medicinal use. To advance the understanding of mulberry genomics and demography, we assembled high‐quality haploid genomes of two widely cultivated mulberry varieties NS14 and QS1, and analysed 376 accessions from 12 countries, including 39 ancient trees
