Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

The Novel ACTC1 p.Gly50Ser Variant Is Associated With Arrhythmia and Secondary Features of HCM Without Hypertrophy

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 7, Page 1742-1748, July 2026.
ABSTRACT The key diagnostic criterion for hypertrophic cardiomyopathy is the presence of otherwise unexplained hypertrophy. Current definitions of HCM rely on specific thresholds to establish a diagnosis, while guideline directed risk stratification algorithms take its magnitude into consideration.

Cytoembryological evaluation, meiotic behavior and pollen viability of Paspalum notatum tetraploidized plants

open access: yesCrop Breeding and Applied Biotechnology, 2016
This study evaluated the mode of reproduction, the meiotic behavior and the pollen viability of three tetraploid plants (2n=4x=40) originated from somatic chromosome duplication of Paspalum notatum plants. The plant WKS 3 changed the mode of reproduction

Current quantitative methodologies for pre-implantation genetic testing frequently misclassify meiotic aneuploidies as mosaic [PDF]

open access: yes
Objective To study the biological origin of chromosomal abnormalities in embryos reported as mosaic following next-generation sequencing (NGS)-based preimplantation genetic testing for aneuploidy (PGT-A) and to assess the accuracy of current NGS-based ...

Cytogenetic Analysis of Altitude‐Associated Chromosome Variations in Campeiostachys nutans From Western Sichuan Plateau Using Multicolor GISH and ND‐FISH Approaches

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
The genomic and chromosomal organization of C. nutans was investigated using GISH and ND‐FISH with four oligonucleotide probes. The results showed that repetitive sequence distribution exhibited genome‐specific patterns: the H genome demonstrated high structural stability with low polymorphism, while the St genome showed moderate variation, and the Y ...

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

open access: yesAndrology, Volume 14, Issue 5, Page 1240-1248, July 2026.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 7, Page 2316-2330, July 2026.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

Analysis of the role of the X/Y homologous gene family Xmr/Sly in murine spermiogenesis [PDF]

open access: yes, 2009
Spermatogenesis is a complex, continuous developmental process that involves the formation of highly differentiated haploid sperm from diploid spermatogonial stem cells.

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice

open access: yesPlant Biotechnology Journal, Volume 24, Issue 7, Page 4689-4703, July 2026.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.
