The potato cyst nematode Globodera pallida overcomes major potato resistance through selection on standing variation at a single locus

New Phytologist, Volume 249, Issue 6, Page 3039-3059, March 2026.
Summary Globodera pallida poses a major threat to potato production, with management strategies primarily relying on genetic resistance. However, increasing virulence in field populations across Western Europe raises major concerns for G. pallida control.

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

Integrative Bioinformatics and Machine Learning Identify Novel Diagnostic Biomarkers and Molecular Mechanisms in Sjögren’s Syndrome

International Journal of Genomics, Volume 2026, Issue 1, 2026.
Background Sjögren’s syndrome (SS) is a chronic autoimmune disorder characterized by significant diagnostic challenges due to nonspecific symptoms and a lack of reliable biomarkers, often resulting in delayed diagnosis and suboptimal patient management.

Histone mRNA is subject to 3’ uridylation and re-adenylation in Aspergillus nidulans [PDF]

, 2021
The role of post‐transcriptional RNA modification is of growing interest. One example is the addition of non‐templated uridine residues to the 3′ end of transcripts.

Exploring the Potential Mechanism of Umbilical Cord Mesenchymal Stem Cell Therapy for Chronic Atrophic Gastritis Based on Multi‐Omics Technology

Stem Cells International, Volume 2026, Issue 1, 2026.
Background Chronic atrophic gastritis (CAG), a prevalent gastrointestinal disorder, is characterized by gastric mucosal atrophy and increased cancer risk. Mesenchymal stem cells (MSCs) exhibit immunomodulatory, anti‐inflammatory, and tissue‐regenerative properties; however, their therapeutic potential for CAG remains underexplored.

PPL2 translesion polymerase is essential for the completion of chromosomal DNA replication in the african trypanosome [PDF]

, 2013
Faithful copying of the genome is essential for life. In eukaryotes, a single archaeo-eukaryotic primase (AEP), DNA primase, is required for the initiation and progression of DNA replication.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

FEBS Open Bio, Volume 15, Issue 12, Page 2001-2020, December 2025.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

Nuclear Surveillance and Degradation of Hypomodified Initiator tRNA\u3csup\u3eMet\u3c/sup\u3e in \u3cem\u3eS. cerevisiae\u3c/em\u3e [PDF]

, 2004
The tRNA m1A58 methyltransferase is composed of two subunits encoded by the essential genes TRM6 and TRM61 (formerly GCD10 and GCD14). The trm6-504 mutation results in a defective m1A methyltransferase (Mtase) and a temperature-sensitive growth phenotype
