Suomen Maataloustieteellisen Seuran TiedoteMy backcross pollinations of 53 spontaneum barleys recurrently with cv. ‘Adorra’ resulted in a maternally inherited, partial spike fertility case assigned “58”. Abnormal kernels, embryos and pollen, triploidy, miniature and streaked plants were among other symptoms. The 58-element greatly enhanced expression of the P-43 multi-ovary mutant in cv. ‘Paavo’

Type II and IV toxin-antitoxin systems coordinately stabilize the integrative and conjugative element of the ICESa2603 family conferring multiple drug resistance in Streptococcus suis. [PDF]
PLoS PathogensIntegrative and conjugative elements (ICEs) play a vital role in bacterial evolution by carrying essential genes that confer adaptive functions to the host.

EccDNA Analysis Provides Novel Insights Into the Molecular Mechanism of Firmness of Fish Fillet [PDF]
Food Science &Nutrition, Volume 13, Issue 5, May 2025.We provide a new and basic eccDNA database for the molecular regulation of muscle firmness in grass carp. The eccDNA abundance in crisp grass carp was significantly higher than that in ordinary grass carp. EccDNAs likely play important roles in the muscle‐hardening of crisp grass carp.

Inheritance of Extrachromosomal Ribosomal DNA During the Asexual Life Cycle of Dictyostelium discoideum: Examination by Use of DNA Polymorphisms [PDF]
Molecular and Cellular Biology, 1985 Wild-type isolates of Dictyostelium discoideum exhibited differences in the size of restriction fragments of the extrachromosomal 88-kilobase ribosomal DNA (rDNA) palindrome. Polymorphisms in rDNA also were found among strains derived solely from the NC4 wild-type isolate.

Transcriptional immune suppression and up-regulation of double-stranded DNA damage and repair repertoires in ecDNA-containing tumors [PDF]
eLifeExtrachromosomal DNA is a common cause of oncogene amplification in cancer. The non-chromosomal inheritance of ecDNA enables tumors to rapidly evolve, contributing to treatment resistance and poor outcome for patients.

Borg extrachromosomal elements of methane-oxidizing archaea have conserved and expressed genetic repertoires [PDF]
Nature CommunicationsBorgs are huge extrachromosomal elements (ECE) of anaerobic methane-consuming “Candidatus Methanoperedens” archaea. Here, we used nanopore sequencing to validate published complete genomes curated from short reads and to reconstruct new genomes.

Cas9‐Rep fusion tethers donor DNA in vivo and boosts the efficiency of HDR‐mediated genome editing [PDF]
Plant Biotechnology Journal, Volume 23, Issue 6, Page 2006-2017, June 2025.Summary Genome editing based on the homology‐directed repair (HDR) pathway enables scar‐free and precise genetic manipulations. However, the low frequency of HDR hinders its application in plant genome editing. In this study, we engineered the fusion of Cas9 and a viral replication protein (Rep) as a molecular bridge to tether donor DNA in vivo, which ...
