Genetic Characterisation of the upp Gene in Bifidobacterium bifidum PRL2010
Microbial Biotechnology, Volume 18, Issue 7, July 2025.In this study, we examined the highly conserved upp gene in bifidobacteria, which encodes uracil phosphoribosyltransferase and plays a role in the pyrimidine salvage pathway. Specifically, we explore its evolutionary trajectory in bifidobacteria, shedding light on its role in microbial competition in the human gut.

Mitochondrial Genome Engineering: The Revolution May Not Be CRISPR-Ized. [PDF]
, 2018 In recent years mitochondrial DNA (mtDNA) has transitioned to greater prominence across diverse areas of biology and medicine. The recognition of mitochondria as a major biochemical hub, contributions of mitochondrial dysfunction to various diseases, and

Plant Biotechnology Journal, Volume 23, Issue 7, Page 2852-2870, July 2025.Summary Pomegranate is an important perennial fruit tree distributed worldwide. Reference genomes with gaps and limit gene identification controlling important agronomic traits hinder its functional genomics and genetic improvements. Here, we reported a telomere‐to‐telomere (T2T) gap‐free genome assembly of the distinctive cultivar ‘Moshiliu’.

The 5S ribosomal RNA gene in Pythium species: two different genomic locations.
Molecular biology and evolution, 1992 The 5S ribosomal RNA (rRNA) genes in eukaryotes may occur either interspersed with the other rRNA genes in the ribosomal DNA (rDNA) repeat, or in separate tandem arrays, or dispersed throughout the genome.

Reconstitution of the complete pathway of ITS2 processing at the pre-ribosome
, 2017 Removal of internal transcribed spacer 2 (ITS2) from pre-ribosomal RNA is essential to make functional ribosomes. This complicated processing reaction begins with a single endonucleolytic cleavage followed by exonucleolytic trimming at both new cleavage ...
