Equine Spermatogenesis: Meiotic Chromosome Behavior and Recombination [PDF]

Studying the spermatogenesis of horse is beneficial for the horse industry by identifying the causes of chromosomal abnormalities, which cause embryonic loss, congenital abnormalities and infertility. Little is known about the spermatogenesis in horse.

Nitrogen‐Starved Wheat: A Multi‐Omics Perspective From Epigenome Regulation to Grain Quality

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This review establishes epigenetic regulation, specifically H3K27ac and H3K27me3 dynamics at nitrogen transporter, assimilation, and storage protein loci, as a principal determinant of cultivar‐specific nitrogen use efficiency in hexaploid wheat, independent of DNA sequence variation, and identifies the rhizosphere microbiome as an integral but ...

Molecular insights and translational opportunities to enhance heat tolerance in rice

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, Volume 14, Issue 6, Page 1579-1589, September 2026.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Variants in ZZS Complex‐Associated Genes TEX11 and M1AP Are Responsible for Male Infertility and Nonobstructive Azoospermia

Andrology, Volume 14, Issue 6, Page 1847-1858, September 2026.
ABSTRACT Background Nonobstructive azoospermia (NOA) is the most severe form of male infertility, with genetic factors contributing to approximately 30% of cases. However, only a small fraction of all NOA cases can be explained by the current genetic findings.
