ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, Volume 68, Issue 11, Page 4052-4070, November 2026.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Chromosome Evolution in Amniote Vertebrates: A Comprehensive Atlas of Karyotypic Diversity From Ancestral States to Rapid Turnover

Molecular Ecology, Volume 35, Issue 21, November 2026.
ABSTRACT The evolution of the amniote genome is characterized by a striking dichotomy between extreme karyotypic stasis and rapid structural innovation. To identify the mechanisms governing this variation, we provide a comprehensive synthesis of chromosome number and karyotype data across non‐avian reptiles, birds and mammals, integrating a century of ...

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

Plant Biotechnology Journal, Volume 24, Issue 11, Page 5719-5728, November 2026.
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Clinical Impact of HLA‐DPB1 Permissiveness Models on Acute GVHD and Survival After Unrelated Allogeneic HCT: A Single‐Centre Brazilian Cohort

HLA, Volume 108, Issue 5, November 2026.
ABSTRACT HLA‐DPB1 mismatches are frequent in unrelated allogeneic haematopoietic stem cell transplantation (allo‐HCT), even among donor–recipient pairs matched at conventional HLA loci. Models including T‐cell epitope (TCE), expression and Predicted Indirectly Recognisable HLA Epitopes (PIRCHE) have been proposed to assess HLA‐DPB1 permissiveness.
