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

American 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.

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

Ecology 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 ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, Volume 26, Issue 7, Page 42-56, July 2026.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

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

Andrology, 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.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, Volume 104, Issue 7, Page 447-456, July 2026.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

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

Journal 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.

Meiotic analysis of two putative polyploid species of Verbenaceae from Brazil

, 2015
The natural occurrence of hybrids and polyploids hinders the precise identification of some taxa in Verbenaceae (Lamiales). Since meiotic studies are useful for understanding the chromosomal behavior of plant species, we have examined the meiotic stages ...

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

Plant 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.
