Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

open access: yesAndrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Early Discrimination of Maternal Haploid and Diploid Maize (Zea mays L.) Seedlings Using Morphological Traits and Random Forest Classifier

open access: yesPlant Breeding, EarlyView.
ABSTRACT Doubled haploid (DH) technology has been widely adopted in maize (Zea mays L.) breeding programs due to its ability to reduce breeding cycle time and optimize costs. Early ploidy identification is essential for maximizing the efficiency of DH production, particularly prior to chromosome doubling.

Viable Triploid Honey Bees (Apis mellifera capensis) Are Reliably Produced in the Progeny of CO2 Narcotised Queens

open access: yesG3: Genes, Genomes, Genetics, 2018
The haplodiploid system of sex determination of Hymenoptera acts as an exaptation for species to evolve novel forms of asexual reproduction including thelytoky (clonal offspring of the mother). During normal reproduction in Hymenoptera, three of the four

First Insight Into Multiple Paternity in the Potato Cyst Nematode Globodera pallida Facing Masculinizing Plant Resistance

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This study demonstrated multiple paternity in the potato cyst nematode Globodera pallida: all females were polyandrous. Moreover, the female mating rate with different males appeared to remain stable, i.e., an average of seven fathering males, throughout the adaptation process to a masculinizing potato resistance.

Current advances in haploid stem cells

open access: yesProtein & Cell, 2019
Diploidy is the typical genomic mode in all mammals. Haploid stem cells are artificial cell lines experimentally derived in vitro in the form of different types of stem cells, which combine the characteristics of haploidy with a broad developmental ...

Copy Number Analysis in Congenital Nevi: Concordance and Diagnostic Limitations of aCGH, sWGS, and Methylation Sequencing

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
Distinguishing proliferative nodules from melanoma in congenital melanocytic nevi remains challenging. While aCGH, sWGS, and methylation sequencing show high concordance for broad CNAs, higher‐resolution methods detect additional focal alterations that can lead to discordant classifications.

Molecular and immunohistochemical characteristics of complete hydatidiform moles

open access: yesBalkan Journal of Medical Genetics, 2017
Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic ...

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]

open access: yesPLoS Genetics, 2016
Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Parthenocarpy and Self-Incompatibility in Mandarins

open access: yesAgronomy, 2021
Citrus reproductive biology is complex. One of its characteristic features is parthenocarpy that enables seedless fruit production. Citrus parthenocarpy and self-incompatibility knowledge is only partial and sometimes discrepant.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,
